Drop-in Spring Clamp Optical Filter Mounts

Overview

Our spring-loaded optical filter mounts do not require tools to secure or change your optical filter, and they can be stacked to provide a wide variety of filtering options. The mounts hold individual filters firmly in place, accommodate round or square filters, and offer a wide variety of post mounting options. The FH-1S and FH-2S use a three-sided, spring-loaded, v-groove clamp that allows quick and easy interchange of the optical filter by simply squeezing the lower portion of the spring-loaded Delrin arm.

Easy Filter Exchange

Our FH-1S and FH-2S Optical Filter Holders use a three-sided, spring-loaded, v-groove clamp to still allow for quick and easy interchange of the optical filter. Simply squeeze on the lower portion of the spring-loaded Delrin arm and insert the filter, and when the arm is released, the filter will be held firmly in place.

Post Mounting Options

The FH-1S, FH-2S and 9861 Filter Holders incorporate an 8-32 (M4) counterbored hole in the center of the base, allowing for easy post mounting with a variety of posts and pedestals.

Hold Round or Square Optical Filters

The FH-1S mount holds 1.0 in. diameter optical filters, while the FH-2S and M-PPF50 mounts hold 2.0 in. square optical filters. The 9861 mount can hold either square or round filters, as well as assorted filter pieces.

Stack Multiple Optical Filters

The 9861 double filter holder allows you to stack two filters of any shape with ease. The FH-1S and FH-2S filter mounts feature two sets of threaded and clearance holes on the face of their base for use in stacking.
