What is the advantage of selecting optical glass?
” The lenses of optical glass mirrors are made from the same material that’s used to manufacture high quality telescope and camera lenses. The lens is precision-ground and hand-lapped, providing an undistorted reflection of unequaled clarity. “How is the magnification effect achieved?” In their standard (non-optical) mirrors, the manufacturer uses very thin 3 mm convex-shaped (balloon-shaped) glass in their 3x and 5x models, which distorts and magnifies the image as needed depending upon the curve of the glass. In their optical mirrors, the manufacturer’s 3x and 7x lenses are crafted with even thicker glass (10mm or 12mm, depending upon the diameter of the mirror and its magnification power), which is machined to obtain a plain convex lens in order to obtain the best reflected image possible with no distortion. “What’s the difference between the ‘finish’ and the ‘casing color’?” “Finish” refers to the color of the trim and pedestal while the “casing color” is the finish of the mirror h
