The investigation showed that there was no significant difference in the proportion of impurities that fell through the
concave grating (Table 1) regardless of the shape of the threshing cylinder's spaces between the rasp bars.

However, RCWA cannot be used to simulate the imaging of a
concave grating in the large free propagation region.
This 16-bit
concave grating spectrometer is USB-2 powered, shock-proof and vibration tolerant with no moving parts and includes the powerful SpectraWiz spectrometer software and development kit.
The CXR-FS system comprises a miniature fiber optically coupled, thermo electrically cooled (TEC) UV-Vis spectrometer with
concave grating, an LED-based excitation source, and a dual-read cuvette sample holder.
The BP1 can also be used to concurrently power a proprietary EPP2000C
concave grating UV-VIS spectrometer and obtain a complete UV-VIS-NIR spectrum.
The concluded TRP Advanced large FOV UV/VIS/NIR/SWIR spectrometers has identified high efficiency reflective
concave gratings working over a large band as a key technology to enable the manufacturing of instruments that encompass the performances of OLCI in terms of optical quality spatial resolution and compactness.
