AR Coating 420-680nm Double-Concave Lenses
AR Coating 420-680nm Double-Concave Lenses
CLZ Optical Co., Ltd. provides bi-concave lenses with a transmittance-enhancing coating in the 420-680nm band. These lenses have both surfaces concave inward, creating a negative focal length characteristic that enables efficient dispersion of incident light and are widely used for beam expansion, image reduction, and the design of specific optical paths. CLZ's bi-concave lenses with AR coating in the 420-680 nm wavelength band are suitable for use in the visible wavelength band. The ability to significantly reduce the reflection loss of light on the lens surface greatly enhances the transmittance of light in this band. This means more light can pass through the lens without damage in the wide range of blue-violet to red light, providing brighter, clearer visual effects and higher energy transfer efficiency for imaging systems, spectral analysis, laser applications, etc.
