Radiometer
Electro-Optical Products

The R-752 universal radiometer has the ability to measure both continuous and pulsed radiation with one detector. It's unique pyroelectric detector/power head design measures CW power from 20 microwatts to 100 watts, in 1/30th of a second, from UV to Far IR. It can withstand power densities exceeding 2.5 KW/cm2. For energy measurements, it provides a dynamic range of 50nJ to 1 Joule and digital event averaging up to 1000 events throughout the entire spectrum. It integrates, digitizes, computes and displays the energy of individual pulses at rates exceeding 120 pps. Also, it can sum up the energies of up to 1000 events to a level of 1 KJ. A large 32 segment analog bar graph and built-in audio tone facilitates accurate laser tuning from across the lab, while the large digital display provides easy reading of the radiation levels. It operates on AC or batteries. It also features auto-ranging, auto-triggering and NVRAM storage of wavelength calibration factors.

The following probes are available:
1) The U-444, for UV applications, and the S-444, for 1064nm operation, silicon probes are ideal for measurements of extremely low level pulsed radiation
2) The P-444 pyroelectric probe is used for both power and energy measurements, it measures radiation from the UV to the Far IR
