McPherson - Windowless, Back Illuminated CCD Sensors
We do not have a wafer fab or foundry for making CCD sensors at McPherson. We buy these cameras. A CCD array detector can speed up data acquisition of spectra – collecting a whole spectrum in the time scanning acquires one point. Direct detection CCD sensitivity is better in the soft x-ray, extreme and vacuum ultraviolet (response graph below). CCDs enable rapid data collection, imaging spectroscopy and more. For now, because pixels are relatively large, monochromator exit slits with single channel detectors provide better spectral resolution and faster data acquisition.
Many companies integrate the same sensors fabricated by companies like e2v in England. We have good experience with different suppliers. Trusted suppliers include Andor-Technology (now Oxford Instruments) and Princeton-Instruments. Princeton`s 64-bit LightField software now controls McPherson’s deep UV and soft X-ray spectrometers and Princeton Instruments soft x-ray cameras too. Integration couldn`t be easier. Other companies like Raptor Photonics and greateyes and even Hamamtsu have items on offer for deep ultraviolet wavelengths.
Our scintillator coatings and microchannel plate intensifier can make any CCD a viable sensor of short wavelength light. Here are a few different ways array detectors can fit to your spectrometer.
- Wide range 1 to 1000 nanometers
- TE Cooled for low noise and stability
- Spectroscopy & Imaging formats available
