IRVINE, Calif., Dec. 31, 2012 — Newport Corp. has introduced the 918D-ST series wand photodiode sensors. The design features a thin-profile wand detector in a sturdy metal housing with integrated calibration data storage and an automatic OD3 attenuator on/off position sensor.
They feature built-in temperature sensing electronics to compensate for temperature variation. The 918D-ST-IR wand operates from 780 to 1800 nm, the 918D-ST-SL from 400 to 1100 nm, and the 918D-ST-UV from 200 to 1100 nm.
A large-area 10 × 10-mm silicon, UV-enhanced silicon or germanium photodetector combines with the ergonomic case design, making the wand photodiodes suitable for applications in laser and other optical power measurements where access or space is limited. When used with select advanced power meters from Newport, the 918D-ST series detectors allow the user to change position of the attenuator without having to reconfigure the power meter, and they produce more accurate measurements by auto-adjusting the responsivity of the photodiode.
The wand detectors are shipping now with a NIST-traced calibration report that details individual detector responsivity, measured with and without attenuator.
