QHYCFW3S 7-position, 1.25" Filter Wheel
Please Note : Image shows two separate versions of the QHYCFW3 filter wheel. If you purchase this item, you will receive only the 7 position wheel.
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.
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.
