Pellicle Beamsplitters
• Extra thin construction
• Elimination of second surface (ghost) reflections
• Elimination of refraction displacement errors
These Pellicle Beamsplitters are ideally suited to laser sampling. Their versatile mounting and light weight construction make them an effective high-quality window, or high-resolution mirror.
The pellicle itself is a delicate, elastic membrane of nitrocellulose mounted on an optically flat aluminum alloy frame. The pellicle is stretched taut over the lapped edges of the frames, ensuring surface flatness. The pellicle thickness is 2 µm and exhibits a thickness uniformity less than 2 wavelengths per 25 mm.
The major advantage of pellicle beamsplitters is elimination of second surface reflections. This is because the membrane is so thin that reflections from the front and back surfaces are essentially superimposed.
