A dichroic filter is an optical element that, based on its special optical thin film structure, is able to selectively reflect or transmit light in a specific wavelength range, while absorbing or reflecting the rest of the wavelength.
Product Overview:
Dichroic filters are made based on the principle of optical thin film interference, which can separate or synthesize light according to wavelength, and the light of a specific wavelength is reflected, and the rest of the wavelength light is transmitted, with high spectral selectivity and stability.
