Optec 50mm Dichroic Red-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. 

  • This Optec Dichroic Red-IR Filter was designed for Tri-color imaging.
  • It measures 50mm in diameter, is 2mm thick and has no cell.
  • The Optec Dichroic Red-IR Filter is intended for factory-installation into Optec 5-position Filter Wheel if chosen at time of filter wheel purchase
  • Product Series

    Optec can supply a full range of filters for the IFW wheel. Filters are easily and safely mounted in the new IFW filter wheel by use of delrin plastic holding tabs and spacers. Filters from 1 to 5 mm in thickness can be accommodated with use of delrin ring spacers. Because the flexible tab and not the head of the screw holds the filter in place, it is impossible for the filter to be damaged by excess over tightening. An ample supple of tabs and spacers are supplied with each filter wheel.

    Filter wheels for both 50mm diameter and 2-inch diameter are available. For special purposes, an 8 position wheel configured for 1-inch filters is offered.
