S100 is a basic wide-range spectrometer that is hard to manage without in any scientific lab, at the educational process, and even in field conditions.

Use of original concave diffraction grating makes the S100 a unique device which allows concurrently get high-resolution of 1 nm within extremely wide spectral range – from 190 to 1100 nm.

Spectrometer S100 is extremely easy and convenient in use: it is calibrated by the manufacturer, does not contain any movable elements, is controlled and powered from the computer via Full-Speed USB interface. Analyzed light is input either through a quartz optical fiber or directly hit the input slit. Upon your request the S100 may be supplied with a filter separating high spectrum orders.

1) max. exposure time is the time when the dark signal reaches 10% of the dynamic range at +250С ambient.
2) antiblooming is a sensor feature eliminating charge overflow from exposed pixels to surrounding pixels.
3) the S8378-512Q linear image sensor provides possibility of control over sensitivity mode: high (HS) or low (LS).

Linear image sensors TCD 1304AP and TCD 1205D of Toshiba installed in the S100-3648 and S100-2048 feature high sensitivity; large quantity of relatively narrow sensor pixels ensures high resolution and precise wavelength detection. However, when recording wide-band spectra with the S100-3648 and S100-2048, spectrum modulation is observed (see below an incandescent lamp spectrum acquired with the S100-3648), thus limiting to some extent their application in spectrometry. The software allows the user to enter correction of recorded signal intensity in a selected spectral range. The manufacturer does not perform the intensity correction.

Linear image sensor S8378-1024 installed in the S100-1024 provides excellent linearity, wide dynamic range and complete absence of spectrum modulation (see an incandescent lamp spectrum recorded with the S100-1024). However, it is characterized by relatively lower sensitivity and due to a wider pixel slightly loses in sense of resolution to devices based on Toshiba arrays.
