The CFH1 Removable Filter Holder is based upon a precision spring-loaded dovetail design, ensuring good position stability and repeatability. The SM05 (0.535"-40) threaded bore accepts Ø1/2" optics up to 0.18" (5mm) thick, fastened with our SM05RR Retaining Ring.
Extra CFH1-F filter plates are available seperately. In addition, the CFH1-B Blank Plate, also purchased seperately, can be used as a manual shutter or machined to suit your specific requirements.
