Model SDH

 High-Aperture Multi-Purpose Spectrometer SDH
FEATURES

The SDH family of spectrometers may be supplied in two versions: the SDH-I model, incorporating one fixed diffraction grating; the SDH-IV model with a four-position turret of diffraction gratings (manual switching)

  • High resolution – up to 0.06nm
  • High aperture ratio of 4.4
  • A wide choice of detectors, including TE cooled models
  • A kit of accessories for light input into the spectrometer
SDH

DESCRIPTION

The standard delivery set contains an 8-position turret with gratings for cutting high spectrum orders (3 standard filters, manual switching), a two-lens UV silica condenser f=16mm, an optical fiber with the SMA-905 adapter, two synchronisation cables (direct and reverse), and control USB-cable. Thus, you can choose the most suitable method of delivering the analyzed radiation to your spectrometer.

The SDH spectrometers are convenient and easy to use: they are calibrated by the manufacturer, do not contain any movable parts, have rigid and thermostable design.

The spectral range and resolution (i.e. grating lines density) are chosen at the time of placing your order. For your convenience the specifications lists the average values of grating dispersion, spectral resolution and multichannel array bandpass of the CCD detector corresponding to a certain grating. Contact a SOLAR LS specialist for more precise calculation of parameters for your spectrometer.

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

OPTIONS & ACCESSORIES

The SDH spectrometer can be supplied with VUV or FWF optical fibers with various lengths.

The SDH 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 SDH 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.

Contact a SOLAR LS specialist to select the complete set of the device that meets the requirement of your instrument complex in the best way.
