Description
Non-polarizing beamsplitter plates are essential components in optical systems, particularly when dealing with high-power lasers. These plates are designed to split or recombine a beam of light without altering its polarization state. This characteristic makes them invaluable in applications where maintaining the original polarization is crucial.
The beamsplitter plates work by allowing two partial beams to travel along different optical paths, which are influenced by the incident angle and the thickness of the plates. This unique property can result in a beam shift, which can be advantageous in certain optical setups. Manufactured from high-quality BK-7 grade A optical glass, these beamsplitter plates ensure superior performance and reliability. The material choice guarantees excellent optical clarity and durability, making them suitable for demanding environments. The plates are available in a range of diameters from 10mm to 50.8mm, providing flexibility for various optical configurations. With a dimensional tolerance of ±0.2mm and a flatness of λ/4 @632.8nm per 25mm, these plates offer precision and consistency in optical performance.
The surface quality of the beamsplitter plates is maintained at a scratch and dig specification of 60/40, ensuring minimal surface imperfections that could affect the optical path. Additionally, the parallelism of 1 arc minute ensures that the beamsplitter maintains the integrity of the beam path, reducing potential deviations. The coatings applied to the surfaces are optimized for an incidence angle of 45°, with surface 1 featuring single wavelength partial reflectance and surface 2 equipped with "V" AR-coatings. These coatings enhance the efficiency and effectiveness of the beamsplitter plates in various optical applications.
