What Are the Key Functions of 1064nm Optical Filters?
The 1064nm high transmission optical filter improves laser transmission efficiency and suppresses background stray light. It serves as a key component in many systems that use 1064nm lasers. These filters help systems maximize laser energy transmission and extract clear signals from complex environments.

Shenzhen Hengda Liyuan Optoelectronics introduced advanced optical vacuum technology that apply depositing nano-materials through ion-assisted evaporation onto a multilayer hard film in a high vacuum environment which the coating layer is firm and has good tightness and small bandwidth drift. The company have been focus on optical coating for more than 17 years ,and the company offer one-stop optical filters solution including Narrow Bandpass Filters, IR cut-off Filters, Longpass Filters, Shortpass Filters, Notch Filters, ND filters, Star filters and Optical sapphire block.
Remark：Because the interference type filter varies its spectral performance at different angles, the spectral parameters usually determine its appearance color; moreover, the pictures in this link may originate from various shooting angles, so the actual color of the parts should therefore refer to the final spectral parameters required.
