SDH-I - High-Aperture Compact Spectrometers
High-Aperture Compact Spectrometers
Zoom in
Printable version
High resolution – up to 0.06 nm
High throughput – F/Number of 4.4
Multiple choice of methods for input of analyzed radiation to the spectrometer

High-aperture compact spectrometers of the SDH-series are available in two versions: SDH-I model containing one fixed diffraction grating and SDH-IV model with a 4-position manually switchable diffraction gratings turret.

All the spectrometers are equipped with an eight-position filter turret for cutting higher spectrum orders (manual switching), a quartz two-lens condenser f=16mm and optical fiber with the SMA-905 adapter, thus providing users with a possibility of selecting the most convenient method of delivering analyzed radiation to the spectrometer.
The below specifications of the SDH-IV spectrometer contain recommended variants of diffraction gratings/multi-channel detectors combination for the most popular spectral ranges.
