✦ Synopsis
Turner. Optical elements of binoculars, microscopes and many other optical products are now coated with anti-reflection films, some as thin as fourmillionths of an inch. The thickness of the film determines its reflecting quality.
The company has prepared, for free distribution, a descriptive brochure on how to get the most out of them giving the characteristics of the new films and brief suggestions.
