These light shields are an 11 inch (279 mm) long piece of bellows tubing with a female-flange on one end and a male-flange on the other. They fold and extend from 3 to 11 inches (76 to 279 mm). You can easily remove a flange, cut the tube to a shorter length and re-assemble the flange. We use these tubes to enclose the beam from a light source to a monochromator; these are not intended to absorb high power radiation. We offer two types: the 77356 has standard set screw type compatible with The Oriel Flanging System. The 71305 has our convenient Quick Connect flanges.
