InGaAs spectrometers

B&W Tek

B&W Tek has recently introduced its enhanced series of TE Cooled fibre-coupled InGaAs array spectrometers - the Sol series. The NIR indium gallium arsenide spectrometers were debuted at SPIE's Optics & Spectrometers conference.

These spectrometers offer extended spectral range and high spectral resolution options along with deeper TE Cooling. All four spectrometers in the series have a USB standard interface for easy integration into OEM systems.

The enhancements of the Sol series near-infrared spectrometers allow users more flexibility in configuring systems specific to their application, with an increase in detection limits of nearly a factor of 10.

The Sol 1.7's TE Cooling has been upgraded from +5°C to -10°C for lower noise and better stability. The spectrometer includes three new grating options, allowing for 18 additional configurations between 900 nm - 1700 nm, and a resolution of 0.2nm. Redesigned electronics for the Sol 1.7 allow this unit to operate with a standard 5VDC power supply, making it even more convenient for OEM integrators and end users alike.

The Sol 2.2 and Sol 2.2A have also been upgraded with three new grating options, allowing for 8 additional configurations from previous models. These new gratings allow for an extended range of 900 nm-2200 nm and higher spectral resolution, measuring less than 2.5 nm for the Sol 2.2.
