Solar LS - Model S90-IR -Compact High-Sensitivity Spectrometer

he high-aperture optical scheme of the S90-IR has no moving parts. The S90-IR case is monolithic and ensures long-time stability of parameters.

The S90-IR spectrometer is easy and convenient to use: it is calibrated by the manufacturer, is controlled and powered from the PC via Full-Speed USB interface. Light input with the use of quartz optical fiber provides flexibility of instrumentation arrangement. The spectrometer has the entrance slit of fixed width and may be used without optical fiber.

Upon Your request, the S90-IR spectrometer can be equipped with high-order separating compound filter designed for operation with broadband spectra.

The S90-IR spectrometer can be supplied with VUV or FWF optical fibers with various lengths.

The S90-IR spectrometer has a wide range of options and accessories that allow efficient collection of light from the sample located at a finite distance and in infinity:

• Condenser PS-2  is designed for collecting light from a sample located at 40 mm distance within a wide spectral range and its effective transmission into an optical fiber or onto an entrance slit of a spectral device.
• Condenser PS-3 is designed for collecting light from a sample located at 29 mm distance within a wide aperture angle and its further transmission into an optical fiber or onto an entrance slit of a spectral device.
• Adapter FA-1 – achromatic adapter for focusing parallel beam to a fiber with 3D-alignment.
• Adapter FA-2 – achromatic adapter for focusing parallel beam to a fiber with an axial alignment.
• Cassegrain objectives allow collecting light from objects located at a distance of 3.5m to infinity.
• Diffuse attenuator FA-3 is designed to attenuate the laser beam while delivering it to a fiber.
• The S90-IR spectrometer can be supplied with a cuvette holder FA-10 and with fiber-optics immersion probes DipProbes with a set of interchangeable tips for liquid handling.
