M72 x 0.75 Mounted Linear Glass Polarizing Filter

Product Details Stackable, Rotating Mount for Easy Integration into Imaging Systems Eliminate Hot Spots and Reduce Glare 95% Polarization Efficiency Also Available Unmounted Mounted Linear Glass Polarizing Filters feature a rotatable threaded mount available in a wide range of standard thread sizes. Linear polarizing filters will transmit a single axis of polarization and can be used to reduce glare and hot spots in imaging systems. Two polarizing filters can be stacked to achieve a variable density effect. Thickness includes a 2mm male thread. Mounted Linear Glass Polarizing Filters have 95% polarization efficiency. The filters are also available unmounted .
