CFH1 (Cage Plate & Filter CFH2 LCP05 CFH1-F Extra Ø1/2" CFH1-B Blank Plate Stackable Design ![]() Please Wait ![]() In addition to cage system compatibility, these mounts can be fastened to Ø1/2" posts via 8-32 (M4) tapped holes. Features
The mounts offered below are for installing a single filter in-line within a cage system. See the Filter Mount Selection Guide to the right for other cage system compatible options, such as Cage Cubes, Filter Wheels, and Sliders. The CFH1(/M) and LCFH1(/M) Removable Filter Holders are based upon a precision spring-loaded dovetail design, ensuring good position stability and repeatability. These filter holders are designed to hold Ø1/2" or Ø1" optics, respectively, using the included retaining ring. Additional plates are available to easily mount and then switch optical components. The CFH2(/M) and LCFH2(/M) Removable Filter Holders are light-tight, stackable filter blocks designed to integrate easily into our 30 mm or 60 mm cage systems or to be post mounted on a breadboard. Unlike the CFH1 and LCFH1, this light-tight design is achieved with a permanent O-ring mounted on the front face and a double-flanged top plate on the removable inner body. The LCP05(/M) 60 mm Cage Plate for Square Filters, has a Ø2" through hole (42 mm clear aperture) and is designed to hold either 2" square or 50 mm square filters up to 4 mm thick. Since the mount is equipped with two spring clips on each side, a filter can be pressed up against either side of the clear aperture. This filter holder is ideal for use with our 2" x 2" Unmounted Absorptive Neutral Density Filters or our Square Colored Glass Filters.

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" (5.0 mm) thick, fastened with our SM05RR Retaining Ring. Extra SM05-threaded filter plates (CFH1-F) are available separately. In addition, the CFH1-B Blank Plate, also purchased separately, can be used as a manual shutter or machined to suit your specific requirements. ![]()
The LCFH1(/M) Removable Filter Holder is a stackable filter block designed to integrate easily into our 60 mm cage system or to be post-mounted on a breadboard. The filter holder offers internal SM1 (1.035"-40) threading with a fixed retaining lip and an SM1RR retaining ring. It can hold Ø1" optics up to 0.29" (7.4 mm) thick. The precision, spring-loaded, dovetail design of the removable inner body ensures reproducible positioning and eliminates unwanted movements to ensure repeatability. Multiple filter holders can be continually stacked in our 60 mm cage system, provided an equivalent length of cage rods is available for support. All four of the cage rods can pass through the cage rod clearance holes on the LCFH1. Extra SM1-threaded filter plate inserts (Item # LCFH1-F) are available separately. In addition, the LCFH1-B Blank Plate Insert can also be purchased separately. The blank plate can be used as a manual shutter or can be machined to suit your specific requirements, with the aid of the center drill mark. ![]() ![]() Click to Enlarge Pushing the adjuster down on the CFH2-V quickly closes the shutter. ![]() Click to Enlarge CFH2 Schematic

The LCFH2(/M) Removable Filter Holder is a light-tight, stackable filter block designed to integrate easily into our 60 mm cage system or to be post mounted on a breadboard. Unlike the LCFH1(/M) above, this light-tight design is achieved with a permanent O-ring mounted on the front face and a double-flanged top plate on the removable inner body. The filter holder insert can accommodate Ø2" optics up to 0.30" (7.6 mm) thick and is equipped with SM2 (2.035"-40) threading on one side and a fixed retaining lip on the other.
