北京波威科技有限公司代理的美国CVI厂家的TFPK低散步偏振片,也称TFPK-Low-Dispersion Polarizers。此分束镜的偏振带宽为100nm at 800nm,有效透光率为96% at 800nm。
产品技术参数描述:
Specifications
Angle of Incidence
72°±2°
Bandwidth
See curve for 800-nm performance.
Extinction Ratio
T p 2/T s 2 > 15:1 where T P and T S are
per-surface transmissions
Reflection Efficiency
R s > 75% each surface. s-polarization reflectivities
of 85% and 95% are available at some sacrifice of p-polarization transmission. Working angle of incidence
will increase.
Transmission Efficiency
T p > 98% for each surface. Slight tilting is required to
find angle of minimum loss.
