Spectrometer SL40-2 Series is a small-size two-channel spectrum analyzer. The SL40-2 Specrtometer comprises two spectrographs (channels) which are arranged in one common housing, and an embedded linear detector. Each of the spectrographs is designed around the original optical schematic (configuration) with aspheric and achromatic objective lenses. The spectrographs offer a focal length of 40 mm and F/4,9. Diffraction gratings with different numbers of lines can be used in any of the two channels of the Spectrometer to allow adjustment both of the spectral range to be detected and the obtained spectral resolution.
The focal plane with spectra produced by each spectrograph coincides with the plane of photosensitive elements of the embedded linear detector. The length of the focal plane of each spectrograph is half the detector (array) length. The linear detector ensures simultaneous detection of spectra from both the spectrographs.
One two-channel optical fiber (one input, two outputs), two single-channel optical fibers or condensers can be used for delivery of light to the SL40-2 Specrtometer.
With use of a two-channel optical fiber the light beam is divided into two equivalent parts (channels) to enter the input port of each spectrograph. The light of the same light source is detected in the two channels of the Spectrometer.
The use of two single-channel optical fibers allows the light from two different light sources to be simultaneously delivered to the Spectrometer and be detected.
The SL40-2 is a compact, small-size, reliable and easy to operate spectrum analyzer. To run the SL40-2 Specrtometer, you just need to couple it to the USB-port of a PC and start Control Program “PSI-Line”.
“PSI-Line” Software is a powerful tool to carry out different type-analyses of the obtained spectra. Power supply to the SL40-2 Specrtometer is provided through the USB port of a PC.
