Infrared (IR) Pellicle Beamsplitters feature thin nitrocellulose beam-splitting membranes mounted in aluminum frames and are designed to have a 45R/55T beam-splitting ratio from 3 - 5µm. The thin nitrocellulose membranes eliminate second surface reflections and beam displacement while minimizing changes in the optical path length. Note: The nitrocellulose membrane of these beamsplitters is very thin and fragile. The membrane should not be touched, and cleaning should be done only with air. We recommend using an air blower as the force from compressed air may damage the membrane.
