ISP Optics offers high performance beamsplitter coatings,
with 50% of the incident beam transmitted and 50% reflected.
CaF2 Beamsplitter plate 50/50
One side is the coated infrared beamsplitter surface and the other side is uncoated.
R/T=50/50+/-10% at 1.5-5.0µm(SWIR-MWIR) + T>2% at 633nm @ 45+/-5 degree AOI
R/T=50/50+/-10% at 2-8µm(MWIR) + T>5% at 633nm @ 45+/-5 degree AOI
ZnSe Beamsplitter plate 50/50
One side is the coated infrared beamsplitter surface and the other side is AR coated.
R/T=50/50+/-10% at 7-14um(LWIR), 45+/-5 degree AOI.
R/T=50/50+/-15% at 5-16um, 45+/-5 degree AOI.
ISP Optics offers two types of dichroic beamsplitters that separate IR from VIS.
"Gold" dichroic beamsplitter transmits visible range (0.4-0.7 µm, Tavg>70%) and reflects infrared range (3-12 µm, Ravg>94%).
"Platinum" dichroic beamsplitter reflects visible range (0.4-0.7 µm, Ravg>85%) and transmits infrared range (3-12 µm, Tavg>85%).
