The laser line dichroic filters reflects one or several laser lines and transmit other wavelengths, it would separate the laser beam from its harmonic wavelength laser light. Variety types of Dichroic Filers are available in Hangzhou Shalom EO: longpass, shortpass, bandpass, bandblocking and colour correction types over a range of wavelengths.
