Sciencetech's FB1T filter box holds one filter per filter box and can accommodate up to 3" x 3" filters. The FB1T filter box is used to stop back reflections from travelling along the path of the incident light. The FB1T filter boxes are stackable, so multiple FB1T filter boxes can be attached if using more than one filter at once is required.
The FB1T has standard mounting for slip rings that are compatible with 2" diameter lens tubes.
For mounting with 1" diameter lens tubes Sciencetech's S4-1D (100-8038) coupling adaptor is required.
No filter holders are included and filter holders are dependent on the size of the filters to be used.
Compatible filter holders are the FT-series (e.g. FT-75).
