30Q20BS.3 76.2 mm Dia. 50:50 (R:T) UVFS Broadband Dielectric Plate Beamsplitter; t=12.5mm 1290-1580nm

The 30Q20BS.3 is a high-quality beamsplitter, specifically designed for use in the 1290-1580nm wavelength range. This beamsplitter is sourced from the reputable vendor MKS/Newport, ensuring reliability and performance. It features a circular geometry with a diameter of 76.2mm and a thickness of 12.5mm, making it suitable for a wide range of optical applications.

The beamsplitter's coating is a key feature, with a front coating of new bs.3 and a back coating of new nc.3. This specific coating allows for a 50:50 (R:T) split, meaning that the beamsplitter reflects 50% of the incident light and transmits the remaining 50%. This makes it ideal for applications where equal distribution of light is required.

The 30Q20BS.3 is a thin lens beamsplitter, which offers several advantages over traditional beamsplitters. Its thin lens design reduces the risk of optical aberrations, improving the overall quality of the beam. Additionally, its broadband dielectric coating ensures high damage threshold and low insertion loss, making it suitable for high-power applications.
