Stylus Inspector Loupe
Gemologist quality loupe by Belomo with all metal housing and triplet glass optics for a bright, clear and close-up view of critical stylus parts especially diamond tip, cantilever tube and bushing. The Belomo loupe features an aplanatic and achromatic triple lens system (corrected for linear and color distortion). 10X and 21mm focal width for ease of use. This superlative quality loupe is made in Belarus by BELOMO, the acronym for Belarus Optiko Mechanichesckoye Obyedinenie (Belarus Optical & Mechanical Association). A joint venture with optics maker Zeiss was begun in 1995. The firm produces lenses and optical elements for microscopes and other optical equipment with ISO 9001 certification. The Belomo loupe is considered by some as one of the finest loupes available—comparable in quality and performance to such exalted names as Bausch & Lomb, Zeiss, Nikon, Kaya and Schneider.
How to use the Stylus Inspector Loupe
A loupe is designed to be used in a well-lighted location. Bring the Stylus Inspector Loupe up to your eye as close as is comfortable against your eyelashes (or near your eyegalsses) but without touching your eye. Be sure to keep both eyes open. It is natural to want to close the other eye but eventually it leads to eye strain more quickly than keeping both eyes open. Keep the gem loupe stationary. Bring the stylus in to the loupe to focus.
Slowly move the stylus back and forth until it comes into focus and maximum clarity. Because the loupe has very strong magnification, the focal range or aperture is very narrow. Slightly move the stone back and forth and turn it around to get different areas of the stylus into focus for examination.
Note: 10X is the standard for diamond and gemstone grading. We do not recommend higher than 10X magnification. It is difficult to focus. More importantly, it would require the user to bring the stylus very close to the lens and this could lead the end-user to accidentally hit and bend the cantilever.
