We offer calibrated and standard photodiode sensors. The calibrated detectors come with NIST traceable spectral responsivity values for every 10 nm over the detector's calibrated wavelength range. The Germanium detectors NIST traceable calibrated responsivity factors cover the 0.7 to 1.8 µm range. The UV Si detectors are calibrated from 200 to 1100 nm.

The flanged detectors are enclosed in aluminum housings with a 1/4-20 tapped hole in the bottom for rod mounting, and a 1.5 Inch Series female flange for direct coupling to Oriel Monochromators and lamp housings.  Shown on the right is the 71582 Silicon detector mounted directly to one of our research housings, looking transversely at the lamp, utilizing the Adapter Kit.

Oriel offers a selection of Thermoelectric (TE) cooled detectors, that allows the direct temperature control of the internal detector element.  The primary benefit of TE cooling is to stabilize the detector responsivity, especially at the extremes of the responsivity range.  The cable connects to one of our 6895X series of digital light intensity controllers (such as our ), while the cable connects to a number of our ILX branded temperature controllers (our shown on the left).
