19-310 12.7 mm Dia. 50:50 (R:T) Nitrocellulose Pellicle Beamsplitter; t=0.002mm 632.8nm

This product is a 12.7 mm diameter, thin beam splitter offered by Edmund Optics. It features a nitrocellulose pellicle construction with a thickness of 0.002 mm, designed for use at a wavelength of 632.8 nm. The beam splitter is a 50:50 (R:T) type, meaning it reflects 50% of the incident light and transmits the remaining 50%.

The front surface of the beam splitter is coated with EDM BS 50R-50T, a coating specifically designed to ensure the desired 50:50 reflection-transmission ratio. The beam splitter's geometry is that of a thin lens, and it has physical data that includes a reflection of 0.5 on the beam splitter and a transmission of 0.5.

According to the vendor's information, this beam splitter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. The beam splitter's thin design and nitrocellulose pellicle construction make it an ideal choice for applications where space is limited and high-quality beam splitting is required.
