SFFH Quick-Release Filter Holder

• Quick-release design, suitable for applications requiring frequent replacement of rectangular filters.
• Built-in rubber pads in both arms to avoid damage to optical components from overpressure.
• For rectangular filters up to 4mm thick.
• M4 countersunk hole for rod mounting.

The SFFH quick-release filter holder is ideal for applications needing frequent filter changes. It adopts a dual-arm locking structure.

Technical Description

• The SFFH quick-release filter holder is suitable for applications requiring frequent filter replacement. It features a dual-arm locking structure, with each support arm equipped with an M2 screw-driven locking device. The clamping force is manually adjusted using a 1.5mm hex key to control the fixation of optical components.

• The inner side of the locking arm is equipped with high-elasticity rubber gaskets, which firmly clamp while effectively preventing filter damage. It is compatible with square or rectangular filters up to 4mm thick and ≥40mm wide. It provides a larger clear aperture, reducing obstruction to the light beam path, and is particularly suitable for large-angle incidence or large-field-of-view optical systems.

• A single M4 counterbore is reserved in the middle of the holder’s bottom, allowing installation on a Ø1/2 inch rod. This facilitates flexible integration into various optical platforms or bracket systems, supporting multi-angle and modular combined use.
