Cardiac surgeon wearing surgical loupes Surgeons in many specialties commonly use loupes when doing surgery on delicate structures. The loupes used by surgeons are mounted in the lenses of glasses and are custom made for the individual surgeon, taking into account their corrected vision, interpupillary distance and desired focal distance. Multiple magnification powers are available. They are most commonly used in otolaryngology, neurosurgery, plastic surgery, cardiac surgery, orthopedic surgery, and vascular surgery.

A pair of loupes with an Ultralight Optics light mounted Loupe lights are used in conjunction with loupes. They are mainly used in the fields of medicine, dentistry and jewelry. Because loupes magnify a small field of vision, the amount of light that is focused into through the loupe is less than what is seen by just the naked eye. The dimness experienced is negligible for a nonprofessional user, but for professionals who require accuracy and precision and work in a confined area like dentistry, a loupe light provides illumination that will dramatically increase the level of detail he/she can see through loupes.

As dental professionals use both hands in performing dental procedures, dental loupes are binocular and usually take the form of a pair of glasses. Some dental loupes are flip-type, which take the form of two small cylinders, one in front of each lens of the glasses. Other types are inset within the lens of the glasses. A typical magnification for use in dentistry is 2.5×, but dental loupes can be anywhere in the range from 2× to 8×.

Loupes are used in a number of industries, notably the jewelry trade, watchmaking, photography, printing, dentistry, education and ophthalmology. Loupes are also used in academia and life sciences, such as geology and biology. Amateur naturalists may also find a hand lens or a loupe a useful tool when looking at or identifying species. They are also used in numismatics and stamp collecting.

Foldable printers, or linen testers Offset and flexographic printing see frequent use of loupes in order to carefully analyze how ink lies on paper. Strippers use loupes in order to register film separations to one another. Pressmen use them to check registration of colors, estimate dot-gain, and diagnose issues with roller pressure and chemistry based on the shape of individual dots and rosettes.

Dental loupes aid dentists, hygienists, and dental therapists to devise accurate diagnoses of oral conditions and enhance surgical precision when completing treatment. Additionally, loupes can improve dentists' posture which can decrease occupational strain. Dental caries, also known as cavities, are most accurately identified by visual and tactile examination of a clean, dry tooth. Magnification enables dentists to improve their ability to differentiate between a stain and a cavity.

Periodontists and hygienists must visualize plaque and calculus to remove it. Magnification can assist dentists and hygienists with identification and removal of plaque and calculus in addition to improving visualization for periodontal surgery. A pair of dental loupes featuring in- lens magnification. There is a loupe light mounted on the bridge of the loupes and side shields (not shown) on the temples to protect a dentist's eyes from splatter.

Loupes are an essential tool in both numismatics, the study of currency, and the related practice of coin collection. Coin collectors frequently employ loupes for better evaluation of the quality of their coins, since identifying surface wear is vital when attempting to classify the grade of a coin. Uncirculated coins (coins without wear) can command a substantial premium over coins with slight wear. This wear cannot always be seen with the naked eye.

Newer technologies are available (e.g. cone-beam CT scanning) that allow more efficient, scientific measurements to be taken of the dimensions of the root canal, however, the use of CT scanning in endodontics has to be justified. Many dentists use dental loupes to perform root canal therapy, and the consensus is that procedures performed using loupes or other forms of magnification (e.g. a surgical microscope) are more likely to succeed than those performed without them.

A simple microscope uses a lens or set of lenses to enlarge an object through angular magnification alone, giving the viewer an erect enlarged virtual image. The use of a single convex lens or groups of lenses are found in simple magnification devices such as the magnifying glass, loupes, and eyepieces for telescopes and microscopes.

Or a triplet may be designed with three spaced glasses, e.g. the Cooke triplet. The former has the advantage of higher optical throughput due to fewer air-glass interfaces, but the latter provides greater flexibility in aberration control, as the internal surfaces are not confined to have the same radii of curvature. achromatic triplet jewellers' loupe Jewellers' loupes typically use a triplet lens.

A loupe A loupe ( ) is a simple, small magnification device used to see small details more closely. Unlike a magnifying glass, a loupe does not have an attached handle, and its focusing lens(es) are contained in an opaque cylinder or cone or fold into an enclosing housing that protects the lenses when not in use. Loupes are also called hand lenses.
|

Stamp collectors employ loupes to improve their ability to evaluate the quality of their stamps. Identifying surface, adhesive, and perforation is vital when attempting to classify the grade of a stamp. Mint stamps (stamps without cancellations) with no wear can command a substantial premium over mint stamps with slight wear. This wear cannot always be seen with the naked eye.

Analog (film) photographers use loupes to review, edit or analyze negatives and slides on a light table. Typical magnifications for viewing slides full-frame depend on image format; 35 mm frames (24×36 mm slides to 38×38 mm superslides) are best viewed at ca. 5×, while ca. 3× is optimal for viewing medium format slides (6×4.5 cm / 6×6 cm / 6×7 cm).

Zeiss initially worked alone constructing and repairing many types of physical and chemical apparatus. Loupes cut from mirror blanks were particularly in demand. Eyeglasses, telescopes, microscopes, drawing instruments, thermometers, barometers, balances, glassblowing accessories and other apparatuses purchased from foreign suppliers were also sold in a small shop. In 1847 he began to make simple microscopes which almost immediately met with especially good commercial success.

Hoya discussed a merger with Pentax into Hoya Pentax HD Corporation during 2007. Hoya's primary goal was to strengthen its medical-related business by taking advantage of Pentax's technologies and expertise in the field of endoscopes, intraocular lenses, surgical loupes, biocompatible ceramics, etc. It was speculated that Pentax's camera business could be sold off after the merger. The merger was initially intended to be completed by October 1, 2007.

"Open surgery" is any surgical procedure, where the incision made is enough to allow the surgery to take place. With tissues and structures exposed to the air, the procedure can be performed either with the unaided vision of the surgeon or with the use of loupes or microscopes. Some examples of open surgery used, are for herniated disc commonly called a "slipped disc", and most types of cardiac surgery and neurosurgery.

The Galilean design is also used in low magnification binocular surgical and jewelers' loupes because they can be very short and produce an upright image without extra or unusual erecting optics, reducing expense and overall weight. They also have large exit pupils, making centering less critical, and the narrow field of view works well in those applications. These are typically mounted on an eyeglass frame or custom-fit onto eyeglasses.

Loupes are used by professional and amateur field biologists for help identifying species in field situations where a full-sized microscope is impractical, but the ability to observe small morphological characteristics is desired. Many floras and diagnostic keys for identifying plant or animal species recommend the use of a loupe, because taxa may be separated by minute details like the presence of hairs, shapes of hairs and glands.

The lower back is commonly affected, as well as the upper back, shoulders and neck. There are a number of recommendations for dentists that can help reduce the risk of developing musculoskeletal pain. The use of magnification or loupes and good lighting aids an improvement in posture by preventing the need to crane the neck and back for better vision. The use of a saddle seat also assists improved posture by keeping the spine in its natural 'S' curve.

Surgery can be done in case a peripheral nerve has become cut or otherwise divided. This is called peripheral nerve reconstruction. The injured nerve is identified and exposed so that normal nerve tissue can be examined above and below the level of injury, usually with magnification, using either loupes or an operating microscope. If a large segment of nerve is harmed, as can happen in a crush or stretch injury, the nerve will need to be exposed over a larger area.

The Company of the Wolf formed during 2005 to provide a vehicle for mediaeval historians and re-enactors living in and around the New England region of New South Wales. Traditionally the Company has retained close links to other groups in Australia, frequently supplying members to reinforce the displays and shows of other groups. The Company is notable for its mascot Loupes De Guerre, or "war wolves". Historically, wolves, or other fierce breeds, would be unleashed before close quarters combat to break and demoralise enemy infantry formations.

The number, size, color, relative location, orientation, and visibility of inclusions can all affect the relative clarity of a diamond. A clarity grade is assigned based on the overall appearance of the stone under ten times magnification, which is a magnification standard for loupes used in the gem world. Most inclusions present in gem-quality diamonds do not affect the diamonds' performance or structural integrity and are not visible to the naked eyes. However, large clouds can affect a diamond's ability to transmit and scatter light.

The village of Le Cambout is served by a boulangerie and a tabac. There is a church in the centre of the village and a separate, well-kept graveyard a little way off. There is a sports field to the west of the village and an area known as L’Étang de gué aux loupes which has facilities such as a lake, children's playground, camping facilities and Boules lanes. There are a number of British-owned gites in the village aimed at attracting foreign tourists to the area.

Together with proper access to the oral cavity, light is an important part of performing precision dentistry. Because a dentist's head often eclipses the overhead dental lamp, loupes may be fitted with a light source. Loupe-mounted lights used to be fed by fiber optic cables that connected to either a wall- mounted or table-top light source. Newer models feature a more convenient LED lamp within the loupe-mounted light and an electric cord coming from either the conventional wall-mounted or table-top light source or a belt clip rechargeable battery pack.

Microsurgical endodontics, the use of magnification devices such as microscopes, and dental loupes, has been widely accepted among endodontists and practitioners; its use is believed to increase accuracy and visualization in the operating field. However, a Cochrane review in 2015 found no evidence to determine whether there is a difference in the outcome of a procedure done by magnification devices or a conventional procedure done with no magnification. The American Association of Endodontists strongly encourages its members to pursue the use of an oral microscope to ensure the highest level of excellence. The use of a CBCT is also becoming the standard of care.
