Filters with Optical Isotropic Wavelength

Abstract

In the present work it is presented the construction of Band-Pass-Mode Filter and Band –Elimination-Mode Filter used for decreasing the track of the excitation lines 536.7nm and 632.8nm, respectively, for Ar+ and He-Ne lasers. Experimental research of CuGaхAl1-xS2 solid compounds in totality with Galan-Thompson polarization prisms has been carried out in order to construct the devices.
