SDH - Kompaktes Spektrometer mit hoher Apertur

SDH
 

Die Spektrometer der SDH-Serie zeichnen sich durch hohe Apertur und Effizienz aus. Sie sind ausgestattet mit einem Gitter oder mit 4-Gitter-Wechsler, einem Ordnungsfilter und Faserkopplung. Diverse Detektoren (Si und InGaAs) für Wellenlängen von 200-1700nm (optional bis 2,5µm) und Auflösungen bis 0,06nm stehen zur Auswahl. Steuerung und Versorgung erfolgt über USB, umfangreiche Software ist im Lieferumfang enthalten.

Features

  • 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

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)

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 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.
