Filter Holder Adapter
When inserting a thin filter into FH-25 or FH-50, the filter may not be securely held, causing looseness. By attaching the filter to the Filter Adapter (FAD), you can securely fix it onto the Filter Holder (FH-25, FH-50) without any looseness.

Filter Holder (FH)
Holders for transmissive optics that do not require optical alignment such as ND filters and color filters.
Designed to accommodate different thicknesses and make it easy to change filters.
The FH-10 utilizes two spring loaded knobs to hold the filter. This maximizes the clear aperture available while providing a secure clamping force.Filter holders can be used with both round filters and rectangular filters. (Note, the FH-10 can only be used with round filters.)
FH-25 and FH-50 are ideally suited for fine intensity adjustment and transmitted wavelength adjustment because these can hold several filters simultaneously.
