20Q40BS.3 50.8 mm Dia. 50:50 (R:T) UVFS Broadband Dielectric Plate Beamsplitter; t=9.4mm 1290-1580nm

The 20Q40BS.3 is a high-quality beam splitter, specifically designed for use in the 1290-1580nm wavelength range. This component is sourced from the reputable vendor MKS/Newport, ensuring reliability and performance. The beam splitter is circular in shape, with a diameter of 50.8mm and a thickness of 9.4mm, making it suitable for a wide range of optical applications.

The 20Q40BS.3 features a 50:50 beam splitting ratio, meaning it evenly divides incoming light between its reflection and transmission paths. This is particularly useful in applications where balanced light distribution is required. The beam splitter's coating is another notable feature. The front surface is coated with new bs.3, while the back surface is coated with new nc.3. These coatings enhance the beam splitter's performance and durability.

The beam splitter's physical data includes a reflection of 0.5 on the beam splitter surface and a transmission of 0.5 on the opposite surface. This data is crucial for designing and simulating optical systems that incorporate this beam splitter. The beam splitter's geometry and material ID (uvfs mal- 1965) are also essential for accurate optical simulations.
