Pericle Beam Splitter
Beam splitter without ghosting 【Features】 ○ Since it is a beam splitter with a thin film of 5μm or 2μm, reflections from the back surface do not create ghosts. ○ In addition to standard round and rectangular frames, custom frames can also be made. ● For more details, please contact us or download the catalog.
A membrane thickness of only 2μm! A pellicle beamsplitter that is free from ghost images and resistant to mechanical shocks and temperature fluctuations.
The pellicle beam splitter is bonded to an aluminum alloy frame (finished in black anodizing) with an extremely thin nitrocellulose film. Due to the very thin film, ghost images caused by unwanted back reflections from the rear side of the film are not observed. Mounting tap holes are provided at the 12 o'clock and 6 o'clock positions of the frame. While it is resistant to mechanical shocks and temperature fluctuations, care must be taken to avoid dust and spray. Do not touch the film under any circumstances (if cleaning is necessary, limit it to blowing away debris with weak compressed air). ■ The optical path lengths of incident light and reflected light are essentially the same ■ Ghost images from the rear side are essentially nonexistent ■ Chromatic aberration is practically negligible for converging/diverging beams ■ Pellicle thickness of 0.002mm *The catalog from Edmund Optics Japan can be downloaded from the link below.
