This is a 25 x 40 mm rectangular beamsplitter, specifically the BHE4007 model from Knight Optical. It is designed to split incoming light beams into two separate beams with a 50:50 (R:T) ratio, meaning it reflects 50% of the incident light and transmits the remaining 50%. The beamsplitter is made of white float glass, a type of soda lime glass known for its clarity and durability.
The beamsplitter has a thickness of 3mm, providing stability and resistance to optical distortion. It is coated with kni bi1 on the front and kni ai1 on the back, which are proprietary coatings from Knight Optical. These coatings enhance the beamsplitter's performance in the 530-1070nm wavelength range.
The BHE4007 beamsplitter is designed in the shape of a thin lens, which helps to minimize optical aberrations and distortions. According to the provided data, the beamsplitter's physical data indicates a 0.5 reflection and 0.5 transmission rate, aligning with its 50:50 (R:T) design.
This beamsplitter is currently in stock and available for purchase on the Knight Optical website. For more information, please refer to the provided weblink.
