IR.3 Extended NIR Photomultiplier Detector

The limit of detection in the NIR wavelength region can be extended from 900nm, with the standard detector, to 1250nm with the IR.3 detector.

Nickel tartrate is a CD standard that is used to demonstrate performance from the near-UV into the near-infrared. The figure shows the CD spectrum of nickel tartrate collected using IR.3 detector under the experimental conditions tabulated. The CD spectrum shown here is the raw (unsmoothed) spectrum.
