5-position Holder for 50mm Diameter Filters

Install or Replace a Filter

The tab mounting filter wheels allow easier insertion of filters. The black delrin tabs and spacers will hold filters from 1 to 5 mm in thickness.

Spacer rings with thickness of 0.75 and 1.50 mm are stacked first in the filter wheel so that the filter’s top surface is just above the level of the tab. The tab is then inserted and held in place with the supplied Phillips pan head screws (4-40 x 3/16 long) so that there is a small amount of pressure on the filter and the delrin tab is slightly bent. Delrin is very resilient and it will not be deformed easily even if the bend is steep. Don’t tighten the three pan head screws until all the tabs are mounted and in contact with the filter. Then tighten each one slightly until the pan head screw is fully seated and the head is not above the surface of the filter wheel.

Two interchangeable filter holders are available for the Motorized Filter Wheels. The 8-position holder can accept up to eight 25mm and 1" diameter filters that are up to 5.5mm in thickness. The 5-position holder can accept up to five 50mm diameter filters that are up to 5.5mm in thickness. Each filter holder can be easily removed from the Motorized Filter Wheel without the use of tools. A hinged door is secured by a single captive thumbscrew; once opened, the filter holder can be extracted and another inserted in its place. The filter holders include an assortment of 0.75mm and 1.5mm thick spacers to accommodate different filter thicknesses. Each filter is held in place by two easily removable plastic tabs.

The filter wheel housing can be mounted using English or metric mounting plates. The English mounting plates are designed with three ¼-20 tapped holes for post mounting, and are compatible with English laboratory tables. The metric mounting plates are designed with three M6 tapped holes for post mounting, and are compatible with metric laboratory tables. C-mount or T-mount adapters are available for easy integration.

The USB-to-serial converter allows USB connection of the RS-232 filter wheel’s control box to a computer that does not have a native COM (RS-232) port.
