BP1073/45nm bandpass filter is a combined configuration, which uses RG715(from Schott) substrate to absorb visible, and reflection other unwanted light by coating. This filter also needs to consider the transmission of 1064nm at 20 degree AOI.
The specifications refers to below:
CWL: 1073+/-4nm
FWHM: 45+/-5nm
Tpeak:>90%
Blocking:OD4 over 200-1200nm
T>80% at 1064nm at 20 degree AOI
Substrate: RG715, from Schott
Size: Dia.25.1X2.5mm
