These linear polarizers have 25% transmittance for unpolarized light. Two crossed sheets have an average transmission of 0.04%. The sheets are neutral gray in color. It can be used as a variable attenuator.
In this model, a linear film polarizer is sandwiched between two polished BK7 glass discs and mounted on a black anodized aluminium threaded mount. The mounts are made with standard threads so that it can be mounted to any Opto-mechanical mount which has a similar thread.
