Optec - Bessell specification B filter for photometry
Commonly refered to as Bessell UBVRI filters, these filters are primarily intended for photometric measurements of stellar objects using a standard color system. They are 5mm thick, 50mm in diameter and have hard AR broad band coatings on both sides.
The Optec IFW Intelligent filter wheel (#17360) is the ideal compliment for holding these filters.
Optec can supply a full range of filters for the IFW wheel. Filters are easily and safely mounted in the new IFW filter wheel by use of delrin plastic holding tabs and spacers. Filters from 1 to 5 mm in thickness can be accommodated with use of delrin ring spacers. Because the flexible tab and not the head of the screw holds the filter in place, it is impossible for the filter to be damaged by excess over tightening. An ample supple of tabs and spacers are supplied with each filter wheel.
Filter wheels for both 50mm diameter and 2-inch diameter are available. For special purposes, an 8 position wheel configured for 1-inch filters is offered.
