Revision 1.1 2 2.1 GENERAL INFORMATION INTRODUCTION The Gentec-EO THZ-D Series is made up of two high performance, thermal power probes…THZ12D a thermopile and THZ9D a Pyroelectric. Each unit is built for durability, compactness and ease of operation. The THZ12D-3S-VP includes an optical absorber that exhibits nearly flat spectral absorption from 10.6 µm to 600 µm. The THZ9D-20mS-BL includes a black coating for broadband response from 10.6 µm to 3000 µm.
Revision 1.1 2.2 THZ-D Series “SMART INTERFACE” CONNECTOR The DB-15 male “Smart Interface” connector contains an EEPROM (Erasable Electrical Programmable Read-Only Memory) programmed with the calibration sensitivity and other data related to the specific THZ-D wattmeter in use. Faster set-ups are obtained because the monitor automatically adjusts to the characteristics of the wattmeter, when the “Smart Interface” is connected to the monitor. The DB-15 “Smart Interface” connector pin-out is (see Fig.

Revision 1.1 3 OPERATING INSTRUCTIONS 3.1 Used with a compatible monitor 3.1.1 THZ9D Or Figure 2.1: THZ9D with monitor Refer to the user manual of each monitor for further information. THZ-D Series Instruction Manual Gentec Electro-Optics Inc.
Revision 1.1 3.1.2 THZ12D Or Figure 2.2: THZ12D with monitor Refer to the user manual of each monitor for further information. 3.1.3 General Instructions 1- Place the detector on its optical stand (Must use a delrin post). 2- Connect the detector to a compatible Gentec-EO laser power monitor (see Fig. 2-1). (Refer to specifications) NOTE: The parameters programmed in the DB-15 “Smart Interface” are for a 1 M load impedance. THZ-D Series Instruction Manual Gentec Electro-Optics Inc.
Revision 1.1 3- Remove the detector's protective cover, when applicable. 4- The THZ9D requires the use of an Optical Chopper running at 10 Hz. Place the optical chopper (SDC-500 or equivalent) into the laser beam path between the laser and the THZ9D. Make sure that the laser beam is fully contained within the 9 mm detector aperture. CAUTION: Be careful not to exceed the maximum levels and densities in: energy, peak power and average power as stated in the specifications pages. NOTE: 3.
Revision 1.1 3.3 THZ9D used with an oscilloscope: Figure 2.3: THZ9D with oscilloscope 3.3.1 General Instructions Please note that the noise equivalent power will depend on the acquisition system. 1- Install the wattmeter on its optical stand 2- Connect the wattmeter to the APM-D (not compatible with a T-RAD Analog) and switch it on. (Battery or power supply needed) 3- Connect the APM-D to the oscilloscope. NOTE: The required load impedance is 1 M and ≤ 30 pF.
Revision 1.1 Gaussian beam stopped at 1/e2) applied to a diameter equal to 80% of the detector aperture. The use of a divergent lens, a Lambertian diffuser such as opal glass, or any other method of beam spreading, is recommended for this purpose. Please take note that all of the laser light must be directed within the detector aperture and that the transmission loss through the optical component must be known.

Revision 1.1 4 DAMAGE TO THE OPTICAL ABSORBER MATERIALS At any time, the beam’s incident area should not be less than 10% of the detector’s aperture. Please check with Gentec-EO to make measurements with such small beams. Damage is usually caused by exceeding the manufacturer is specified maximum tolerances: - Average Power Density - Peak Power Density - Single Pulse Energy Density Refer to the THZ-D Series wattmeter specifications pages.

Revision 1.1 6 6.1 APPENDIX A Recycling and separation procedure for WEEE directive 2002/96/EC. This section is used by the recycling center when the detector reaches its end of life. Breaking the calibration seal or opening the detector will void the detector warranty. The complete detector contains 1 Detector with wires or DB-15. 1 CD (instruction manual, software and drivers) 1 calibration certificate 6.2 Separation: Paper: certificates Wires: Cable Detector.
Revision 1.1 7 Appendix B: THZ detectors calibration Now for the first time, Gentec-EO has developed a rigorous calibration method and new thermal THz detector that allow absolute power and energy measurement based on a validated reference curve from 10 µm to 440 µm (30 THz to 0.70 THz). The purpose of this application note is to explain the new method of calibration and validation for Gentec-EO THz detectors and to characterize its new spectrally flat THz Thermal Probe.
Revision 1.1 Pyroelectric THz probes cannot be considered as a reference detector for this portion of the Terahertz spectrum, but can be used for relative measurements over the entire THz spectrum (30 THz to 0.1 THz).
Revision 1.1 THE NEW CALIBRATION METHOD 1. Gentec-EO calibrates its THZ12D-3S-VP detector using a stable 10.6 μm laser and a NIST Gold Standard Power Detector. 2. A validation of the detector is made to ensure its good working condition and that its behaviour conforms to the specifications at this wavelength and to other detectors of this type according to the reference absorption curve. 3.
