The 10Q20HBS.11P is a high-energy Nd:YAG laser beamsplitter, specifically designed for use with 266nm wavelengths. This beamsplitter is a product of MKS/Newport, a renowned vendor in the optical industry, and is currently in stock with valid weblinks provided for further information.
This beamsplitter is of the Thin BS subtype, featuring a circular base shape with a diameter of 25.4mm. The physical data of this beamsplitter indicates a 50:50 (R:T) split, meaning it reflects and transmits 50% of the incident light each. The beamsplitter's thickness is 6.1mm, and it is made from UVFS material, identified as "uvfs mal- 1965" in the item data.
The coating on the front of the beamsplitter is "new hbs.11p", which is specifically designed for use with the 266nm wavelength. The beamsplitter's shape is that of a Thin Lens, and its geometry is such that it will effectively split incoming laser beams at this specific wavelength.
