This product houses a motorized filter wheel and provides a means for computer control of the excitation wavelength of your microscope.  It is show here connected between the lamp housing and the epi-illumination optics of a Nikon Diaphot illuminator.  With this inexpensive add-on to your microscope, and with either the PC-DAQ or RS-DAQ Controller, you can quickly change the illumination wavelength to make multiwavelength measurements without having to change or move the dichroic cube.  Either of these controllers can interface to a computer.  In addition, the RS-DAQ Controller allows you to control this filter wheel assembly using either a keypad, TTL signals or via RS-232 commands.

If you have ever used similar devices by other manufacturers, you'll appreciate the advanced design of the Model MFW-4.   You'll appreciate these key features:

• It only takes minutes to change an individual filter or a filter wheel.
• The motorized filter wheel is easily removed with one screw.
• There is no chance of accidentally misaligning the illumination system.
• You do not have to disconnect the lamp housing to change filters or the filter wheel.
• Our RS-DAQ Controller will operate two filter wheels and two shutters, in addition to collecting fluorescence data and analog data. 

To change the filter wheel in the Model MFW, 4 thumb screws are removed to open the assembly and one additional screw is removed, allowing you to lift out the motor assembly.  The filter wheel is self-aligning and there are no wires to reconnect.

Features

• The Microscope Filter Wheel Assembly features an easily removed and self-aligning filter wheel.  The filter wheel can hold four one inch diameter filters. 
• Can be controlled with either the Model PC-DAQ or Model RS-DAQ Controller.
• Available with microscope-specific mounts or with standard C-mount threads. 
• Mounts are available to connect the Filter Wheel Assembly to a light guide or fiber optic cable.  This feature allows you to place your microscope illuminator on the bench top to eliminate microscope vibration.  Contact us for details.
• Contains a computer-controlled shutter.
• Includes power supply (not shown).
