B&W Tek Sol 2.2A


Sol 2.2A

The Sol™ 2.2A NIR spectrometer is a high performance linear InGaAs array spectrometer with an available spectral range of 900-2200nm. Its 256 pixel detector provides high throughput and large dynamic range with TE Cooling down to -15oC via a built-in 3-stage cooler. The built-in autozero function automatically reduces dark current and dark non-uniformity, resulting in an increased signal-to-noise ratio. Software control allows you to choose from four types of operation modes; Maximum Dynamic, High Dynamic, High Sensitivity, and Maximum Sensitivity in order to optimize your spectrometer for your specific application.     
The Sol 2.2A NIR spectrometer features a SMA 905 fiber optic input, built-in 16-bit digitizer, and is USB 2.0 plug-and-play compatible. This spectrometer is ideal for demanding applications in process monitoring, quality control, and materials identification. Customized spectral resolution and application support are also available for OEM customers.
