OSE-CLDM

The principle of the cold mirror is reflecting the visible range light and leave the UV range light to transmit.
Dichroic filter transmit only visible light and reject ultraviolet and infrared light.
Filters are designed to divide sharply the wavelength color by transmitting the short wavelength and cutting off the long wavelength.
Filters are designed to divide sharply the wavelength color by transmitting the short wavelength and cutting off the long wavelength.
It is available to cut the excitation laser beam and extracted with high transmittance Raman shifted light on the longer wavelength side with a sharp rise.
Divides sharply the color of wavelength by reflecting the short wavelength and transmitting the long wavelength.

DOT-Variable-Filters

Powerful continuously tunable filters from Delta Optical Thin Film for spectroscopy, characterized by high transmission and high edge steepness.
