Edmund Optics Inc. Pellicle Beamsplitters 3" Dia 40R/40T NT39-487

No Ghost Images from Second Surface Reflections No Chromatic Aberration with Converging Beams No Change in Optical Path Length Pellicle Beamsplitters are very thin nitrocellulose membranes bonded to lapped aluminum frames that feature no ghost images from second surface reflections. To ease system integration, Pellicle Beamsplitters offer mounting holes on the underside of the frame. Pellicle Beamsplitters are not affected by mechanical shock or climate variations, but must be protected from dust and spray to avoid damage to the pellicle membrane. Note: Extra care must be taken when handling.For lasting protection, each Pellicle Beamsplitter is supplied in a functionally designed plastic container. Also available are 90° and 45° rotational mounts for all Pellicle Beamsplitters. These mounts are designed for easy integration of our Pellicle Beamsplitter into any system. Each can be mounted to a benchplate via ¼-20 screws.
