CLZ Optical Co., Ltd. can provide achromatic lenses coated in the 420-680nm band, with Ravg<0.35% @ 420-680nm @ 0° AOI. Achromatic lenses coated in the 420-680nm band are mainly used to minimize reflections, increase transmissions, and improve optical performance. Achromatic lenses, are made of two concave and convex lenses with different refractive indices and different dispersion rates, which can reduce or eliminate chromatic aberration to a larger extent. 

In this band, coated lenses can significantly reduce the reflection of light on the surface of the lens through specific coating techniques, such as transmittance enhancement film (reflection reduction film), thus increasing the transmittance of light. This coating technology is widely used in a variety of optical devices, such as camera lenses, telescope lenses, etc., to improve imaging quality and performance.

CLZ provides a variety of sizes and other coating options to meet customer needs for different bands and applications.
