Precision Broadband Polka-dot Beamsplitters 250nm – 2000nm. Made in the USA, Available Today
01 Jun 2020
Optometrics’ broadband polka-dot beamsplitters are produced using photolithography to apply a precise and repeating pattern of tiny reflective ‘dots’ on a transmissive substrate. An optical beam is split by reflection and transmission based on the aspect ratio of the area covered by the reflective dots to the area of the uncoated transmissive substrate. These polka-dot beamsplitters are minimally sensitive to angle of incidence, making them well-suited for use in many advanced optical systems.
Standard Inventory Options:
o Diameters at 12.7mm, 25.4mm, 38mm, and 50.8mm
o Squares at 25.4mm, 38mm, and 50.8mm
Have a specialized need? We can produce polka-dot beamsplitters on alternate substrates that extend operating ranges, tailor the reflection to transmission ratio, assemble into mounts, as well as size and shape the substrate to your requirements. Send us your specs for a custom quote.
