Interchangeable detector probes and instruments now provide near-IR spectral response from 0.9 to 1.7 um

Lake Oswego, OR — Spectrum Detector, Inc., a leading manufacturer of standard and custom detectors, electronics and instruments for measuring optical power and energy, recently announced a near-IR addition to its revolutionary deltΔ Joulemeter Series. The deltΔ NIR Joulemeter provides near-IR spectral response from 0.9 to 1.7 um, while also offering numerous performance advantages unique to the deltΔ Series of joulemeters and radiometers.

Compact, flexible and economical, the deltΔ Series' design is unlike any other on the market: the user simply plugs a deltΔ probe into an analog power module (APM) to mate with oscilloscopes and lock-in amplifiers, or plugs the probe into a digital USB-based electronic module (DPM) to create a complete PC based energy meter. Powerful LabView software controls range, wavelength, trigger level, graphic displays and much more. Measurement performance rivals that of advanced readout-based meters; the deltΔ NIR Joulemeter features germanium or InGaAs detectors, 10 fJ sensitivity, high voltage responsivity (10KV/J) and high rep-rate capability. It is ideally suited for measuring laser pulse energy from 1 to 40,000 pps, and measuring pulse energy of eye-safe lasers.

It's easy to tailor the deltΔ for a specific measurement need. A full range of smart deltΔ probes is plug-and-play compatible with the analog and digital power modules. Probes include Si, Ge and InGaAs photodiodes or pyroelectric detectors, covering the spectrum from DUV to FAR IR and even the THz region. Each probe includes an EEPROM that identifies the type of sensor, its voltage response and wavelength correction factors for the digital electronics. In addition, an SM1 threaded front bezel makes it easy to add filters, apertures, lenses, optical holders and more.

Design flexibility is another hallmark of the deltΔ Series. The low-profile probes and compact power modules are optimal for on-board applications such as laser diagnostics or control. OEM versions include bare-board configurations complete with shielded cables that plug directly into the principal system's processing board. The low-profile probes are also ideal for performing measurements in tight spaces.

"The deltΔ Series gives users the choice of multiple joulemeters and radiometers for less than the price of a single readout-based system," said Don Dooley, president of Spectrum Detector. "Flexible and affordable, the deltΔ Series is the perfect fit: it fits the performance requirements, the physical requirements, the budget requirements, even future requirements."
