Polka-Dot Beamsplitter 12.7mm Sq 30R/70T -- NT47-611
from Edmund Optics Inc.

UV to MWIR Spectrum Coverage. Many Beamsplitting Ratios Available. Not Angle Sensitive. Offering a distinct advantage over standard dielectric beamsplitters, Polka-Dot Beamsplitters have a constant reflection/transmission ratio over a large spectral range. The UV grade fused silica substrate has a... [See More]

Polka Dot Beamsplitters
from Newport Corporation

Our 50/50 Polka Dot Beamsplitters are UV fused silica substrates coated with aluminum and SiO protective overcoat in a 'polka dot' pattern. Optimized for white light illumination applications, they provide two unique advantages over traditional dielectric beam splitters: they are neutral over the... [See More]

Polka-Dot Beamsplitters Series
from Shimadzu Corporation

Polka-Dot Beamsplitters comprise a glass substrate with an aluminum coating in a polka-dot pattern. Incident light is reflected from the coated areas but transmitted through the non-coated areas. This splitting mechanism achieves a light split ratio that is almost independent of the light angle of... [See More]
