Simply place the lens or mirror in the holder and adjust the three arms to hold it. A set screw in each adjustable arm ensures that the mirror or lens will remain in place. The holder snaps into the Basic Optics Track and is designed to position all mirrors and lenses at the same height as the rest of the Basic Optics System components.

How It Works

The holder has three sliding arms that can be adjusted for different-sized lenses. Each arm is marked with a range of diameters corresponding to the diameter of the lens to be held, from 20 mm to 75 mm. Line up the appropriate diameter marks on the two lower arms with triangular marks on the ring. Rest the edge of the lens in the lower two arms then slide the top arm down. A set screw in each adjustable arm ensures the lens or mirror will remain in place.
