◆ Features
This is a dichroic beamsplitter, specifically designed for the separation and combination of different wavelengths in laser systems. Through its special multi-layer dielectric coating design, it achieves efficient transmission of specific wavelengths and efficient reflection of other wavelengths, and is widely used in optical systems that require multi-wavelength operation.
It features high transmittance and reflectance, with both the average transmittance and average reflectance reaching over 90% within the specified wavelength band range.
Excellent spectral performance and high optical precision.

Optical Path Design: Incident light must be directed onto the coated surface at the specified angle.
Mechanical Mounting: Must be installed using specially designed mounts that precisely control the angle.
Cleaning Protocol: Avoid organic solvents. Use dry, clean compressed air or nitrogen gas for gentle blowing.
Coating Maintenance: Avoid mechanical contact or friction on the coated surface.
Packaging and Storage: Each filter should be individually packaged to prevent abrasion and stored in a dry, clean environment.
