1 PH SERIES PHOTO DETECTORS
1.1 INTRODUCTION
The Gentec-EO Photo Detector family includes nine photo detectors sensors..
The PH100-Si, PH100Si-HA detectors use a silicon photodiode.
The PH100-SiUV, PH10B-Si, PE10B-Si, PE3B-Si detectors also use a silicon photodiode but have
enhanced sensitivity at shorter wavelengths.
The PH20-Ge, PH5B-Ge, PE5B-Ge detectors use a germanium photodiode.
The PE3B-In detectors use a InGaAs photodiode.
All detector heads are 27.4mm thick by 38.1 mm in diameter.
Table I. Measuring ranges of Gentec-EO PH photo detectors
Configuration PH100-Si series PH100-SiUV series PH20 series
Detector alone 0.3 nW to 30 mW 0.3 nW to 4 mW 2 nW to 30 mW
With OD-0.3 attenuator
With OD-1 attenuator
-
3 nW to 300 mW
0.6 nW to 8 mW
3 nW to 38 mW
-
20 nW to 300 mW
With OD-2 Attenuator 30 nW to 750 mW 30 nW to 30 mW 200 nW to 500 mW
Note: quoted maximum ranges are average power at the 1064 nm wavelength for PH100-Si and PH20-Ge, 532 nm for PH100-
SiUV, and 850 nm for PH100-SiUV with OD-2
quoted minimum ranges are average power at the 980nm for PH100-Si, 850 nm for PH-100-SiUV and 1550 nm for PH20-
Ge (Minimum ranges = 30 X NEP)
Table II. Measuring ranges of Gentec-EO PH-B and PE-B photo detectors
PH10B-Si → 1.5nW to 200µW PE10B-Si → 1.5 pJ to 0.15µJ
PH5B-Ge → 1.2nW to 40µW PE5B-Ge →
PE3B-Si →
PE3B-In →
500 fJ to 3.0nJ
8 fJ to 30pJ
15 fJ to 300pJ
Note PH : quoted minimum and maximum ranges are average power at the 633nm for PH10-Si and 1310nm for PH5B-Ge
(Minimum ranges = 30 X NEP). The M-Link was used for those ranges.
Note PH : quoted minimum and maximum ranges are average power at the 633nm for PE10/3B-Si and 1310nm for PE3/5B-Ge/In
(Minimum ranges = NEE). The M-Link was used for those ranges.
The PH and PE series are supplied with a 180 cm long flexible cable terminated with a DB-15
"intelligent" male connector, for use with Gentec-EO Monitors.
NOTE: To eliminate possible damage, do not carry the detector using the connector cable.
The PH and PE photo detectors may also be supplied with a stand.
