Why scope lens with coating
Jan 20, 2018

Coating is to prevent the reflected light from light on the harm caused by a technical treatment. Fine coating is often used chemical treatment, so plated film is not easy to wipe off, the coating also appears to be natural and gentle. According to the process of coating in the optical sight is divided into single-layer coating and multilayer coating (MC). Optical aiming mirror coating with a single layer of blue film is the most common, but also a few share the use of multi-layer coating. Multi-layer coating can better reduce the various wavelengths of light on the lens reflectivity, in order to improve the overall sight of the color reproduction. The simplest way to distinguish is: single-layer coated lenses reflect a single color in daylight. The multi-coated lenses in different positions under the angle showing a variety of colors of soft reflective.

Because of the direct light, so if a good mirror objective multilayer coating has done very good, then there is no need to multilayer coating on the eyepiece, the general all coated mirror eyepiece has also been coated, the general eyepiece coating is a single film. Please be sure to be able to distinguish between multi-layer coating and single-layer coating coating nature, so as not to be deceived
