Manufacturer's part number :


Manufacturer Altechna


Description :

Mid-IR waveplates are zero order half waveplates and quarter waveplates from cadmium thiogallate (CdGa2S4) with clear aperture from 10mm up to 18mm for the range 2,8 - 9,0microns. Dielectric AR coatings for the mid-IR range are also available in order to enhance the performance of the waveplates. Characteristic plates thickness is 0,5 - 0,9 mm.
