Improvement for Compatibility
Our new version of the QHYCFW3 Color Filter Wheel has been improved for compatibility. The original product can only be used to fix 1.25-inch mounted filters, while the updated version can be fixed with 31mm unmounted filters through the new-added screw holes.
Our 2nd generation filter wheels used a gear drive while this 3rd generation filter wheel uses a friction drive with zero backlash. It also positions and stops with high precision.
Medium size. The QHYCFW3M supports supports a carousel holding five 2-inch mounted or 50mm unmounted filters or a carousel holding seven 36mm unmounted filters. The thin version of this filter wheel is 17.5mm thick and the standard version is 21.5mm thick.
