Warsash Scientific offer a near-IR addition to the Delta Radiometer/Joulemeter series from Spectrum Detector.
The Delta NIR Joulemeter provides near-IR spectral response from 0.9-1.7um, while also offering numerous performance advantages unique to the Delta Series of joulemeters and radiometers.
Compact, flexible and economical, the Delta Series’ design is good. The user simply plugs a Delta probe into an analogue 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.
The Delta NIR Joulemeter features germanium or InGaAs detectors, 10fJ sensitivity, high voltage responsivity (10KV/J) and high rep-rate capability.
It is suited for measuring laser pulse energy from 1 to 40,000pps and measuring pulse energy of eye-safe lasers.
It is easy to tailor the Delta for a specific measurement need. A full range of smart Delta probes is plug-and-play compatible with the analogue 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 feature of the Delta 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 suitable for performing measurements in tight spaces.
