50mm Dichroic Green-IR Filter
Optec offers an exclusive set of parfocal wide band LRGB and narrow band H-Alpha and OIII intended for CCD astro-imaging. These filters are 2mm thick, 50mm diameter and are made to the highest standards for high transmission and minimum wavefront distortion. The unique construction with the hard dielectric layers placed on only one side of the filter substrate avoids multiple reflections between the two sides found in most filters of this type. Halos and ghost stellar images are avoided.
