Warranty

First Year Warranty

The Gentec-EO power and energy detectors carry a one-year warranty (from date of shipment) against material and /or workmanship defects when used under normal operating conditions. The warranty does not cover recalibration or damages related to misuse.

Gentec-EO will repair or replace at its option any wattmeter or joulemeter which proves to be defective during the warranty period, except in the case of product misuse.

Any unauthorized alteration or repair of the product is also not covered by the warranty. The manufacturer is not liable for consequential damages of any kind. In the case of a malfunction, contact the local Gentec-EO distributor or nearest Gentec-EO office to obtain

a return authorization number. Return the material to the appropriate address below. Contacting Gentec Electro-Optics Inc. To help us answer your calls more efficiently please have the model number of the detector you are

using ready before calling Customer Support.

Lifetime Warranty

Gentec-EO will warranty any power and energy detector head for its lifetime as long as it has been returned for recalibration annually from the date of shipment. This warranty includes parts and labor for all routine repairs including normal wear under normal operating conditions.

Gentec-EO will inspect and repair the detector during the annual recalibration. Exceptions to repair at other times will be at Gentec-EO’s option.

Not included is the cost of annual recalibration or consequential damages from using the detector.

Version 2.2 iii

The only condition is that the detector head must not have been subject to unauthorized service or damaged by misuse. Misuse would include, but is not limited to, laser exposure outside Gentec-EO’s published specifications, physical damage due to improper handling, and exposure to hostile environments. Hostile environments would include, but are not limited to excessive temperature, vibration, humidity, or surface contaminants; exposure to flame, solvents or water; and connection to improper electrical voltage.

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.

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,

Contacting Gentec Electro-Optics Inc.

1.2 PHOTO DETECTOR CONNECTORS

1.2.1 DB-15 “intelligent” connector and INTEGRA connector.

The DB-15 male "intelligent" and INTEGRA connectors contains an EEPROM (Erasable Electrical Programmable Read-Only Memory) that stores information such as the model of the detector, the calibration sensitivity of the available spectral range with or without attenuator and the applicable scales for that specific PH and PE Series head. Wavelengths are not available where the sensor physical properties don’t allow it.

The Gentec-eo monitors or PC-GENTEC-EO use the data in those connectors to adjust their characteristics automatically to the power sensor being connected. No calibration procedure is required when installing the power heads, allowing for faster set-up.

NOTE : Consult Gentec-Eo for supply voltage requierements
