Description

Non-Polarizing Plate Beamsplitters are essential optical components designed to divide an incident monochromatic beam into reflected and transmitted components with a specified intensity ratio. These beamsplitters are meticulously engineered to maintain the polarization characteristics of the incident beam, making them ideal for applications where polarization preservation is crucial. The innovative design involves coating one side of the plate with an all-dielectric, non-polarizing, partial reflection coating, while the reverse side is treated with a high-efficiency, narrowband, anti-reflection coating.

The construction of these beamsplitters utilizes high-quality materials such as BK7, UVFS, and ZnSe, ensuring exceptional performance and reliability. The precise angle of incidence is set at 45º, which is a standard in the industry for optimal operation. The surface quality of these beamsplitters is meticulously controlled, with specifications such as a surface figure of λ/20 at 632 nm for BK7 and UVFS, and λ/40 at 10.6 µm for ZnSe, ensuring superior optical clarity and minimal distortion.

Rocky Mountain Instrument Co. is committed to delivering high-quality optical solutions, and their non-polarizing plate beamsplitters exemplify this dedication. With a focus on precision, these beamsplitters offer a diameter tolerance of +0.000", –0.010", and a thickness tolerance of ±0.010". The wedge is maintained at ≤ 3 arc minutes, and bevels range from 0.010" to 0.030" at 45º, ensuring a high degree of accuracy and consistency. The clear aperture is centrally located and covers 85% of the diameter, maximizing the usable area of the beamsplitter.

Reflectance levels are carefully controlled, with specifications ranging from 10% to 90% ± 3%, and the anti-reflection coating ensures that unpolarized reflectance is kept at R ≤ 0.5% at 45º. These precise specifications make the non-polarizing plate beamsplitters from Rocky Mountain Instrument Co. a reliable choice for those seeking to maintain the integrity of their optical systems.
