We make some of the best Optical and Laser Test Instruments and Sensors in the Industry. Measure Power... pW to W. Measure Pulse Energy... fJ to J. Measure a single pulse or up to 130,000 pps. Performance per dollar can't be beat!

mach 5 100kHz Digital Joulemeter
The world's first and only 130kHz Digital Joulemeter. Capture every pulse from your DPSS or Fiber Laser in real time. Store up to 4 Million pulses at max rep rate. Display them in a strip chart or histogram. Send them over the full speed USB to your PC for further analysis. 5 Joulemeter probes cover the range from 0.19 to 6.0 µm and pJ to mJ.

delta Digital Joulemeter or Digital Power Meter Multi-channel
Our small compact delta Probes provide a tremendous number of options in your Laser Lab. Use them one at a time to measure power or energy, or use multiple probes limited only by the number of USB connections available on your PC. USB power and control make the products easy to use in mulit-channel optical experiments or production test sets. Stand alone LabView Software included.

SXI-D Single or Dual Channel Joulemeter/Ratiometer
To get started using our SXJ-D Joulemeter probes all you need is a USB cable, our Applications Software and your computer. Download our software, plug in the USB and begin pulse energy measurements single or dual channel. Need to normalize the data you're taking? Use our free Dual Channel Software to divide the Signal by the Reference channel. Don't look any further for the best Joulemeter / Ratiometer on the market.

Large area, 25 mm Analog or Digital Joulemeter Probes
These new large area Pyroelectric Joulemeter probes are part ot the delta product line and can be used in the analog mode with delta-APM for high rep rate energy measurements or digital mode at up to 1500 pps with our delta-DPM. Measure lasers with large beams or divergent sources using the large area detector.

High Sensitivity, Digital Optical Power Meters
The delta Power probes come in three models; Silicon, Germanium and InGaAs. Measure from pW to mW across the spectrum from DUV to Near IR. USB power and communication make for easy plug and play set up. Add ND filters or our DIGS-1 Integrating sphere to measure up to 2 Watts.

Trad Broadband Radiometer for Far IR, Extreme IR and THz
Introducing Trad the most sensitive, stable Pyroelectric Radiometer on the market. It features unique DSP Lock In Software that maximize performance and convenience. Measure from 0.1 to 3000 µm (yes THz radiation) and 50 nW to 50 mW. It easy ... pick a range, set the filter tau, hit the zero key ... and then make the measurement.
