Our DIA™ AZUR coating reduces eye strain and fatigue caused by digital screens and ultimately helps maintain your visual health. This coating is specifically designed for screen users and protects your eyes from harmful blue light & UV rays.

This advanced anti-reflective coating is included with your sunglasses order and protects against distracting reflections. It protects against UV rays being reflected into the eyes by blocking UV light reflected off the rear lens surfaces and enhances your visual comfort & protection for great sunglasses quality.

A thin achromat can be corrected for third-order spherical aberration, coma, and axial chromatic aberration. The combination consists of a positive and a negative element. To eliminate axial chromatic aberration, a simple relation between powers and Abbe numbers of the two elements must be met. This relation is

These choices are a sound starting point that lead quickly to good solutions in terms of optimization with the computer after adding thicknesses and spacings.

The radii as a factor of an achromat’s focal length are listed in the table below for two objectives: one for the MWIR and one for the LWIR region. For the MWIR lens, silicon and germanium have been the materials chosen, and the combination Amtir-1/zinc sulfide was selected for the LWIR objective. Amtir is an acronym for amorphous material transmitting infrared radiation. The composition of Amtir-1 is 33% Ge, 12% As, and 55% Se.
