1 PH SERIES PHOTO DETECTORS
1.1 INTRODUCTION
The Gentec-EO PH Series photo detector family includes three photo
detectors sensors (PH100-Si,
PH100-SiUV and PH20-Ge).
The PH100-Si detectors use a silicon photodiode. The PH100-SiUV detectors also use a silicon
photodiode but have enhanced sensitivity at shorter wavelengths. The PH20-Ge detectors use a
germanium photodiode. All three 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
0.6 nW to 30 mW
0.6 nW to 2.8 mW
2 nW to 30 mW
With OD-1 attenuator
6 nW to 300 mW
6 nW to 25 mW
20 nW to 300 mW
With OD-2 Attenuator
60 nW to 750 mW
60 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
Table II. Measuring ranges of Gentec-EO PH-B and PE-B photo detectors
PH10B-Si
→
50pW to 200µW
PE10B-Si
→
1.5 pJ to 0.16µJ
PH5B-Ge
→
10pW to 32µW
PE5B-Ge
→
500 fJ to 3.2nJ
Note: quoted maximum ranges are average power at the 1047 nm wavelength for Ge and In
quoted minimum ranges are average power at the 633nm for Si.
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.
Call your nearest Gentec-EO distributor to replace the sensor
or to recalibrate the head. See p. ii,
