The groove frequency of the grating determines two key aspects of the spectrometer’s performance: the spectral resolution and the wavelength coverage. The higher the groove frequency the more resolution the instrument will achieve; however, the wavelength coverage will be less. Inversely, decreasing the groove frequency increases wavelength coverage at the sacrifice of spectral resolution. With over twenty-five gratings to choose from we can customize your application needs.
The blaze angle or blaze wavelength of the grating is also a key parameter in optimizing the spectrometer’s performance. The blaze angle determines the maximum efficiency the grating will have in a specific wavelength region. We have a variety of blaze angles available per groove frequency to match your application needs.

The standard Sol™ 2.2 features a TE Cooled 256 (standard) element linear InGaAs CCD array Detector with a pixel format of 256 x 1 elements @ 25μm per element and a height of 250μm with 256 effective (Active) pixels. Each pixel represents a portion of the spectrum and as the incident light strikes the individual pixels across the CCD the electronics can then translate and display their intensity using our software, BWSpec™
The quantum efficiency (QE), dynamic range (DR), and noise level of the array detector largely dictates the spectrometer sensitivity, dynamic range and signal-tonoise ratio. The spectral acquisition speed of the spectrometer is mainly determined by the detector response over a wavelength region.
Using BWSpec™, the detector mode can be switched between High Sensitivity and High Dynamic modes allowing for a greater control over the detector’s sensitivity.

The Sol™ 2.2 products are based on extended NIR array detectors with low dark current performance. The extended spectral response into the longer wave NIR allows for more precise analysis models to be built when probing into the overtone rich NIR bands. This enables for better detection limit to be achieved as well as more accurate predictions. This example describes a portable device for raw material identification applications using a Sol™ 2.2 engine and a dark field probe with extended shaft. The device is proven to be very effective in applications where the portability, stability and measurement precision are met.
