Hamamatsu Photonics has launched a new spectrometer that provides high-speed detection of multiple wavelengths at photon counting light levels. The A10766 spectrometer includes a multianode photomultiplier tube (PMT) and a polychromator like the H7260 series.
The A10766 Spectrometer
The spectrometer is available in four grating types with 300, 600, 900 and 1200 gr/mm groove densities. It has a small footprint that makes it suitable for integrating into an end user system. The A10766 is compatible with Hamamatsus’s 32 or 16 channel PMTs. Various options provided by the device dictate the resolution, blaze wavelength, spectral width and spectral range specifications.
The A10766 has a spectral response of 200 - 900 nm with a high S/N than traditional CCD array spectrometers. When a 1200 gr/mm grating and a 32-channel PMT are used, a resolution of 6.3 nm/ch can be achieved.
End users can custom design the light input optics or can easily attach an optional fiber bundle. The A10766 spectrometer can measure lower, variable light intensities by utilizing a PMT instead of a silicon image sensor. This feature is the major advantage of the A10766 spectrometer compared to other spectrometers available in the market.
