Partial Reflectors

Dispersive Coatings

In the Ti:Sapphire range and other bands, tightly toleranced partial reflectors are needed to split the beams or to couple out a certain proportion while keeping the GDD under control.

R 83% 1020-1040 nm /0° low GDD
[B-11074]R 83% 1020-1040 nm /0° low GDD

1020–1040 nm: R ± 0.5% vs. curve; | GDD (R) | < 20 fs² (IBS-coating)

R 99% 690-1050 nm /20° p low GDD
[B-11214]R 99% 690-1050 nm /20° p low GDD

690–1050 nm: R ± 0.25% (goal ± 0.1%) vs. curve (IBS-coating)

T 1-25% 680-1010 nm /0° low GDD
[B-11263]T 1-25% 680-1010 nm /0° low GDD

Tolerance for transmission: ± 0.2% absolute or ± 10% of target value (IBS-coating)
