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.

Friction Drive
━━━━

No Backlash
Precision Positioning

Regarding the evolution of the motor drive, our 2nd generation filter wheels used a gear drive while this 3rd generation filter wheel uses a friction drive that with zero backlash. It also positions and stops with high precision.

Four Models
━━━━

Small, Medium
Large, Extra-Large

There are four versions of the 3rd generation QHYCFW3 filter wheel: QHYCFW3XL (extra-large size), QHYCFW3L (large size), QHYCFW3M (medium size), and QHYCFW3S (small size). Both the QHYCFW3M and QHYCFW3S are also available in a standard version (-SR) and thin version (-US). For details, please see the specifications page.

Hybrid Stepper Motor
━━━━

Super Thin
Enclosed Motor

QHYCCD selected a high quality ultra-thin hybrid stepper motor for the 3rd generation filter wheel design. Compared to the PM stepper motor used in many filter wheels, the hybrid stepper motor has higher precision, smaller step angle, and is more expensive. The motor is enclosed to prevent dust from entering the motor, thus improving reliability and motor life. The direction of filter rotation can be reversed: The filter carousel can be rotated clockwise or counterclockwise to complete the rotation quickly which is very convenient.

Two Control Modes
