Oriel 7072 Photodiode Detection System Controller 110V Newport Optical Lab

Oriel 7072 Photodiode Detection System Controller 110V Newport Optical Lab

The Oriel Corporation Model 7072 is a benchtop photodiode detection system controller designed to interface with photodiode detectors for precise photocurrent measurement in optical research and laboratory settings. It conditions and amplifies the low-level current output from a connected photodiode, displaying the measured signal on both a front-panel LED digital readout and an analog meter for quick reference. The unit was manufactured in April 1984 at Oriel Corporation's facility in Stamford, Connecticut.

Applications

The Oriel 7072 is part of Oriel Corporation's line of optical detection instruments, designed for use with silicon photodiodes, UV-enhanced photodiodes, and other current-output detectors on optical bench setups. Controllers of this type are used to measure light intensity, laser power, and spectral response in research and industrial optical systems — reading the tiny photocurrent generated by a detector and scaling it to a usable voltage output or display reading via the selectable multiplier range. Typical applications include monochromator output measurement, laser beam characterization, UV/visible/NIR irradiance monitoring, and photometric calibration work. The ambient suppress function allows the user to null out background illumination, isolating only the signal of interest. Oriel Corporation was a major U.S. manufacturer of optical instruments and components; the brand is now part of Newport Corporation. Equipment of this generation remains in active use in university and industrial optics labs maintaining legacy Oriel optical bench systems.
