Product Family Description

  • 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.
