SPDMHx Series 5 Appendix
1
) The active area of the integrated Si-APD is larger than 100
m
m.
SPDMH2F and SPDMH3F are optimized for optical fibers as specified above. The pre-aligned GRIN lens fo-
cuses the light onto a spot of <70
m
m diameter in the center of the detector.
2
) Specifications are valid for modules without FC-connector.
