The S100 is a basic wide-range spectrometer which is hard to manage without in any scientific laboratory, for spectroscopy education at colleges and universities, and even in field conditions.

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

The S100 spectrometer is convenient and easy to use: it is calibrated by the manufacturer, does not contain any movable parts, is controlled and powered from the computer via Full-Speed USB interface.

The S100 can be triggered from your light source with standard TTL trigger pulses via connector BNC-58. The S100 is also able to produce TTL trigger pulses.

The S100 complete set contains USB control cable, direct and reverse synchronisation cables and UV optical fiber.

The spectrometer is able to operate without the optical fiber with analysed light directly steered to its input slit.

Upon your request the S100 may be supplied with an order sorting filter separating high spectrum orders.

Specific features of the S100 spectrometer depend on the type of the selected detection system.

Linear image sensors TCD 1304 and TCD 1205 of Toshiba installed in the S100-3648 and S100-2048 feature high sensitivity; large quantity of relatively narrow pixels ensures high resolution and accurate wavelength determination. However, when recording wide-band spectra with the S100-3648 and S100-2048, spectrum modulation is observed (refer to inlay SPECTRA ACQUIRED WITH THE S100), thus limiting to some extent their application in spectrometry. The software allows the user to perform calibration of the S100 spectral sensitivity in a selected spectral range. Factory calibration of the S100 spectral sensitivity is not provided.

The S8378-1024 linear image sensor installed in the S100-1024 model demonstrates excellent linearity, wide dynamic range and absence of spectrum modulation. However, it is characteriaed by lower sensitivity and due to a relatively wider pixel slightly loses in sense of resolution to the S100-3648 and S100-2048 based on Toshiba arrays.

1) Max. exposure time is the time when the dark signal reaches 10% of the dynamic range at +25°C ambient.

2) Antiblooming is a sensor feature eliminating charge overflow from exposed pixels to surrounding pixels.

3) The S8378-1024 linear image sensor provides possibility of control over sensitivity mode: high (HS) or low (LS).
