• Holds Six or Twelve Filters
• Accepts 1"/25 mm or ½"/12,5 mm Diameters
• 12 Index Positions for Precise Movement
Our filter wheels offer the flexibility of using up to six (1" or 25 mm) or twelve (1/2" or 12,5 mm) different filters.
The wheel assembly can be clicked into 12 fixed positions. Retainer rings included with the filter wheels can
hold a maximum filter thickness of 4 mm. The C-Mount Adapter allows the use of C-Mount components,
including our C-Mount Lens Mounts, which can hold filters of varying size and thickness. The filter wheel
assembly has a 1/4-20 tapped hole at the base for mounting. Filter Wheel Only (#56-783 & #58-183) can be purchased
separately for switching wheels on the assembly without removing filters. Common applications include
fluorescence imaging, DNA sequencing, attenuating low power lasers, and variable filters for machine vision.

Miniature Motorized Filter Wheels are ideal for space
constrained applications that require spectral selection,
such as fluorescence microscopy, color CCD
photography, or photometry. These stepper motor
driven, optical encoder regulated filter wheels are designed
to repeatedly select absolute positions either
manually using a push button or remotely through
an RS-232 or USB 2.0 interface. Miniature Motorized
Filter Wheels feature two aperture positions, at
12:00 and 9:00, and a digital display which shows the
current filter position. The six position filter wheel
accepts 25 mm filters, while the twelve position filter
wheel accepts 12,5 mm filters. The base of the unit
features six threaded mounting holes to ease system
integration, including one ¼-20, two #8-32, one M6,
and two M4.

These Motorized Filter Wheels are ideal for a number of automated applications requiring spectral selection
or light intensity control. The RS-232 filter wheel can be controlled directly via a control box, or remotely
using an RS-232 interface. The USB filter wheel requires a PC connection for motorized operation. Both
Motorized Filter Wheels include a Windows®-based graphical user interface, filter wheel housing with integrated
stepper motor, USB or RS-232 cables, and 12VDC power supply. Note: Filter holder sold separately.
