BSW23R 25 x 36 mm 50:50 (R:T) IR Fused Silica Plate BS; Coating: 0.9-2.6 µm; t=1 mm

The BSW23R is a high-quality beam splitter (BS) offered by Thorlabs, designed with a rectangular base shape and thin lens characteristics. This component is specifically engineered for the infrared (IR) spectrum, with a wavelength of 633 nm, making it suitable for a wide range of applications in this region of the electromagnetic spectrum.

The BS23R boasts a robust construction, with a width of 36 mm and a height of 25 mm, ensuring efficient beam splitting. The thickness of the beam splitter is 1 mm, contributing to its overall durability and stability. The beam splitter's coating, identified as 'tho 50 uv bs 9002600', is designed for the wavelength range of 0.9-2.6 µm, further enhancing its performance in the IR spectrum.

This beam splitter offers a 50:50 (R:T) split ratio, meaning it reflects 50% of the incident light and transmits the remaining 50%. This characteristic makes it an ideal choice for applications requiring equal distribution of light. The physical data provided indicates that the reflection and transmission coefficients are both 0.5, further confirming its 50:50 split ratio.

The BS23R is available for purchase directly from Thorlabs, and the link provided in the item data indicates that it is currently in stock, ensuring quick delivery for your optical project needs.
