Our Edge Grip™ filter wheels offer a unique clear edge design minimizing the wheel size. Its Edge Grip™ clamping mechanism firmly secures the filter without the use of tools.



Obstruction Free Optical Filter Mounting

Icon-Obstruction

Our patent-pending Edge Grip™ mounting mechanism clamps only the lower part the optical filter leaving the edges of the filter unobstucted. This enables an eight position 1.0 inch filter wheel to fit in the envelope of a six position wheel.

Add and Remove Optical Filters With Ease

Filter

Our Edge Grip™ mounting mechanism uses a thumbscrew to secure the optical filter. No tools are required. Up to 4 mm thick optical filters can be secured in the filter wheel.

Wheels for 1 inch round or 2 inch square filters

The FWH1S is a unique indexed four-position, clear edge filter wheel for holding 2.0 inch square optical filters.
