高速濾光片轉盤使用高性能的伺服電機與利用稀土磁體, 通過反后座力傳輸提供一個極限扭矩，從而轉化出極限速度,讓濾光片轉盤進行旋轉。
HS-625型號：相鄰濾光片間的轉換時間可以達到23ms；最長距離180 度轉輪可放置3個濾光片的轉換時間為45ms。
HS-632型號 , HS-1025型號和HS-1032型號：相鄰濾光片間的轉換時間可以達到30ms；最長距離180 度轉輪可放置5個濾光片的轉換時間為90ms。
High-performance servo motors featuring rare earth magnets coupled with backlash-free power transfer provide ultimate torque which
translates to ultimate speed.
Adjacent filter distance is traveled in as fast as 23ms on the HS-625 model and 30ms on the HS-632, HS-1025 and HS-1032 models,
while the longest distance (180 degree wheel turn corresponding to three filter positions on the HS-625 and HS-632 and five positions
on the HS-1025 and HS-1032) is covered in 45ms on the HS-625 model and 90ms on the HS-632, HS-1025 and HS-1032 models.
Wheel Design
Weight-reduction features have been added to the wheel design for maximum speed. High accuracy and reliable operation is achieved by using custom designed components and precision machining. The filter wheel doubles as a pulley, reducing the number of parts necessary for efficient power transfer and maximizing the torque delivered by the motor.
Deep Pockets
HS filter pockets accommodate a wide selction of filters up to 9mm thick. The HS-1025 model holds up to ten filters with 25mm diameter; HS-1032 holds up to ten 32mm filters; the HS-625 holds up to six 25mm filters; the HS-632 holds up to six 32mm filters. Additional flexibility is provided by combining the 32mm wheels with optional 32mm-to-25mm adapters or other custom holders. The filters are secured in place by threaded retainers.
Filter Access
An oversized opening complemented by a threaded lid provide convenient access for filter replacement eliminating the need to disassemble the unit.
Filter Position Indicator
On the HS-1025 and HS-1032 models, the current filter selction as well as the position aligned with the filter replacement port is indicated through small openings near the wheel pivot. On the HS-625 and HS-632 models, the filter pocket index is visible when replacing the filters through the access port.
Integrated Electronics
All of the drive and control electronics facilitating the functionality of the HS models are contained in the filter wheel housing. This convenient solution eliminates the need for an external controller and the associated wiring hassles. It is still possible to operate multiple filter wheels through the same serial port by connecting them in daisy-chained mode. Simply connect a computer to the incoming port and a second wheel to the outgoing one to achieve functionality equivalent to a two-wheel system driven by a central control unit. Up to three filter wheels can be operated from the same serial port. Aside from motor drive and control circuitry, the integrated circuit board features a shutter controller allowing for a direct connection of a shutter without the need of external drive electronics.
