The FH-2R Stackable Filter Holder offers a convenient, economical system for mounting 2.0 inch diameter circular filters. The mounting system consists of a threaded holder with a Delrin retaining ring to hold the optic firmly but gently. In addition, the FH-2R has a set of M3 threaded and clearance holes located on the upper and lower face of the holder for ease in stacking. Two M3 Screws are included with each mount. The holder incorporates 8-32 and M4 threaded mounting holes for post mounting on English and Metric SP and MSP Series Posts, as well as PS Series Pedestal Posts. The front of the holder also has two clearance holes, which can be used for face mounting or used with a threaded rod (not supplied) to form low-cost optical systems.
