30Q40BS.3 76.2 mm Dia. 50:50 (R:T) UVFS Broadband Dielectric Plate Beamsplitter; t=12.5mm 1290-1580nm

The 30Q40BS.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 of the thin BS variety, featuring a circular base shape with a diameter of 76.2mm and a thickness of 12.5mm, making it suitable for a wide range of optical applications.

The 30Q40BS.3 boasts a 50:50 reflection to transmission ratio, providing a balanced split of the incident light. The front surface of the beam splitter is coated with new bs.3, while the back surface is coated with new nc.3, both of which contribute to its broadband dielectric properties. These coatings ensure high damage threshold and low absorption, making the beam splitter an excellent choice for applications that require high power and precision.

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 ensures a consistent and predictable performance, making the 30Q40BS.3 an ideal component for applications that require precise light control and manipulation.
