325nm narrow band filter
325nm narrow-band filter can separate the filter of specific wavelength band, and has high transmittance in its transmission band. The upper and lower edges of the transmission characteristic curve are very steep, slightly deviate from the transmission area, and the transmittance is almost zero at once. Multilayer dielectric film is adopted, which has almost no light absorption, high transmittance and high wavelength separation efficiency.
The 325nm narrow-band filter has two forms: with and without mirror ring. The filter with mirror ring is easy to operate and fixed to the support. The filter can be selected from a variety of wavelengths in the ultraviolet spectral region of 325nm to the infrared spectral region of 1064nm.
