The BSX18 is a high-quality Beam Splitter from Thorlabs, designed with a circular geometry and a diameter of 2 inches (50.8 mm). It features a thickness of 8 mm, making it a robust and durable option for various optical applications. This Beam Splitter is of the Thin BS type, which means it has a low profile and is less likely to introduce optical aberrations.

The BSX18 is designed to operate at a wavelength of 633 nm, making it suitable for applications that use red light. It comes with a specific coating on the front side, identified as "tho 9010uvbs12001600". This coating is a crucial part of the Beam Splitter's functionality, as it controls the reflection and transmission of light. In this case, the BSX18 has a reflection rate of 0.9 and a transmission rate of 0.1, following the 90:10 ratio (R:T).

The material of the BSX18 is UVFS, identified as "uvfs mal- 1965" in the item data. This material is known for its excellent optical properties, making it a popular choice for Beam Splitters and other optical components.

The BSX18 is currently in stock and available for purchase through the Thorlabs website, as indicated by the "weblink status" in the item data. For more detailed information, you can refer to the vendor's official product page at https://www.thorlabs.com/thorproduct.cfm?partnumber=BSX18.
