Delta Series Radiometers/Joulemeters

These small, modular detector probes and instruments are ideal for the lab bench, production test bed or on board your laser. Select Si, Ge and InGaAs photodiodes or Pyroelectric detectors to cover the spectrum from DUV to FAR IR and even the THz region. Plug the probes into an analog power supply (APM) for use with oscilloscopes and lock-in amplifiers, or plug them into a digital USB-based electronic module (DPM) for powerful PC control. LabView software and drivers provide dual channel and single channel measurement. Measure from fJ to mJ and pW to mW.

STEP: Temperature Controlled, Ultra-Stable Pyro Radiometer

This ultra-precise radiometer employs a large area, broadband pyroelectric hybrid detector packaged with a single-stage TE Cooler to control its temperature to 0.05° C from 20 to 30° C. As a result, the voltage response of the STEP-45 probe is stable to 0.01% over the same temperature range. Further, a black absorbing coating is spectrally flat from 0.25 to 15µm. The system is an excellent IR calibration standard for broadband or spectral measurements. Measure from 10 nW to 10 mW.

JUST ADDED: STEP-45 and STEP-49

Ge And InGaAs Analog Joulemeters

Optimized for pulsed lasers in the 0.8 to 1.8 µm spectral region, the SGJ-A-5 and SIJ-A-3 near-IR analog joulemeters are a great match to Ti:Sapphire Lasers, OPOs and other "eye safe" pulsed lasers. The SGJ offers the broadest spectral response, while the SIJ has the greatest sensitivity. Measure from pJ to nJ.

Pyro TRAP Radiometers

Based on a unique Wedge TRAP configuration developed at NIST Boulder, these analog and digital solutions feature unprecedented ±1% calibration uncertainty, high spectral absorbtion (>98%) and spectral flatness from 0.25 to 15.0 µm. They include a large area black pyroelectric detector and large broadband mirror in a 15° wedge configuration. The analog SPT-AR-TRAP is ideal for use with a lock-in amplifier, while the USB-based digital SPT-DRTRAP includes full-featured LabView application software and drivers for use with your PC. They’re an excellent choice as broadband and spectral calibration standards.

Pyro TRAP Joulemeters

This family of passive, analog and digital joulemeters leverages the Wedge TRAP concept inspired by NIST Boulder – taking full advantage of the unique flat spectral response of this design. They’re ideal “in house” golden standards for calibration of all your pulsed laser joulemeters. Further, create an automated calibration station with the digital model SPT-DJ-TRAP and stand-alone LabView software and drivers. Measure from uJ to mJ and from 0.25 to 14 µm.

Optical TRAP Power Meter

We’ve enhanced our 4X passive optical TRAP with a new 5X optical TRAP design and mated it to our powerful digital electronics. The result is the optimum power meter for measurements from 0.2 to 1.0 µm in the pW to mW range. The system features incredibly low calibration uncertainty from 0.41 to 0.90 µm of less than 0.5%, and is useful from 0.2 to 1.0 µm. The model SST-D-TRAP is a USB-based digital instrument that includes full featured LabView applications software and drivers. Use it to calibrate and correlate all your optical power meters.
