BST12 Dia:1in 70:30 (R:T) UVFS Plate Beamsplitter; Coating: 1.2-1.6 µm; t=5 mm

The BST12 Dia:1in 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 25.4 mm and a thickness of 5 mm, making it suitable for a wide range of optical applications.

The beamsplitter is made from UVFS material, identified as MAL-1965 in the material database. It is specifically designed for use at a wavelength of 633 nm, providing a precise and reliable performance in this spectral range.

The BST12 is coated with a front coating, THo 7030UVBS12001600, which is a unique coating developed by Thorlabs. This coating is designed to provide a 70:30 (R:T) split, meaning that 70% of the incident light is reflected while 30% is transmitted. This split is crucial in many optical systems where the careful management of light is required.

The beamsplitter is shaped as a thin lens, which is a type of lens where the thickness of the lens is significantly less than the diameter of the lens. This shape provides a number of advantages, including a reduced weight and a simplified integration into optical systems.

In terms of physical data, the beamsplitter has a reflection of 0.7 and a transmission of 0.3. These values are consistent with the 70:30 (R:T) split mentioned earlier.

The beamsplitter is currently in stock and available for immediate purchase. More information about this product can be found on the Thorlabs website, including pricing and shipping details.
