BQP4033 40 mm Dia. 50:50 (R:T) N-BK7 Precision Plate Beamsplitter; t=6mm 530-1070nm
The BQP4033 is a 40 mm diameter, 6mm thick Beam Splitter from Knight Optical, designed for use in the near-infrared spectrum, specifically between 530-1070nm. This precision plate beamsplitter is part of Knight Optical's 'Precision Range' and offers a 50:50 (R:T) split, ensuring equal reflection and transmission of light.
The beamsplitter is made from N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material makes the BQP4033 suitable for various applications requiring high-performance optical components.
The front surface of the beamsplitter is coated with KNI Bi1, a broadband anti-reflection coating that reduces surface reflections and improves transmission. The back surface, on the other hand, is coated with KNI AI1, a highly reflective coating that enhances the reflection capabilities of the beamsplitter.
The BQP4033 features a thin lens shape, which is beneficial for applications where space is a constraint. Despite its thinness, it maintains a high level of durability and precision, making it an ideal choice for various optical systems.
