BST06 Dia:0.5in 70:30 (R:T) UVFS Plate Beamsplitter; Coating: 1.2-1.6 µm; t=3 mm

The BST06 Dia:0.5in 70:30 (R:T) UVFS Plate Beamsplitter is a high-quality optical component sourced from Thorlabs. This beamsplitter is designed with a circular geometry, featuring a diameter of 12.7 mm and a thickness of 3 mm, making it a robust and compact solution for various optical applications.

The beamsplitter is made from UVFS material, identified as MAL-1965 in the Thorlabs material database. This material is known for its excellent optical properties, making it suitable for use in a wide range of wavelengths. In this specific beamsplitter, the wavelength of operation is 633 nm.

The BST06 features a 70:30 (R:T) beam splitting ratio, meaning that approximately 70% of the incident light is reflected, while the remaining 30% is transmitted. This ratio is consistent across the specified wavelength range of 1.2-1.6 µm, providing a reliable and predictable performance.

The front surface of the beamsplitter is coated with a thin film coating, specifically the THo 7030UVBS12001600 coating. This coating enhances the beamsplitter's performance by ensuring high reflectivity and transmission within the specified wavelength range.

In terms of physical shape, the BST06 is designed as a thin lens, which contributes to its compactness and ease of integration into optical systems. The beamsplitter's thin lens shape also helps minimize optical aberrations, ensuring high-quality optical performance.
