This OptoSigma product, the PDBS30-25.4C1.5, is a beam splitter with a diameter of 25.4 mm and a thickness of 1.5 mm. It is designed for use in the UVFS material range, specifically for wavelengths between 250 and 2200 nm. The beamsplitter is of the polka dot plate type, which is a specific design of thin beam splitters.
The beamsplitter has a 30:70 (R:T) ratio, meaning that it reflects 30% of the incident light and transmits 70%. This ratio is crucial in determining the functionality of the beamsplitter in various optical systems. The coating on the front surface of the beamsplitter is 'opt pdbs30', which contributes to its specific reflectance and transmittance characteristics.
The beamsplitter is shaped as a thin lens, which is a type of lens with a small thickness compared to its diameter. This shape allows for minimal distortion and loss of light due to refraction. The beamsplitter is currently in stock and available for purchase, as indicated by its 'Valid - in stock' web link status.
