Model : HO-SP-S100MA | HO-SP-S100SA

Scanning spectrometer is specially designed and developed for industrial and academic research laboratories in the fields of biology, chemistry, physics, environmental science and engineering. This device works in the wavelength range of 190 to 1100nm. Scanning spectrometer can rapidly scan a range of wavelengths and record light intensity at each wavelength.

This instrument uses a concave mirror to collimate the light from an input port. Input and output ports of the spectrometer are fitted with precise micrometer controlled variable slits. A plane holographic grating is used to diffract the input light that is subsequently focused by a second concave mirror.

Designed for low light
spectroscopic application

The holographic gratings used in the instrument minimize stray light for the highest sensitivity and accuracy. A stepping-motor controlled sine drive positions the grating, which is mounted on a precision rotary table. The sine drive delivers a linear relationship between stepper motor motion and wavelength of interest. It includes a mechanism to change the wavelength selected by the software and to record the resulting changes in the measured quantity as a function of the wavelength.

The software developed for the instrument has facilities for setting up and calibration in addition to scanning and manual readout. Scanning is possible for a desired wavelength range too. This feature can save time whenever full wavelength range scan is not necessary. The software saves and displays the data acquired on MS Excel sheet. This helps to plot graph with ease whenever required.

Heavy duty aluminium construction is used for high stability with respect to vibration and thermal effects. Multiple accessory options allow the user to configure the system for custom applications. The basic system and accessories are designed in modular fashion. More and more accessories can be added as the applications expand.

There are two types of single channel detectors for using with scanning spectrometers, photomultiplier tube (Model : HO-SP-S100MA) and silicon photo diode (Model : HO-SP-S100SA). For general emissionand bsorption experiments, scanning spectrometer with silicon photo diode is suitable. It can be used for spectroscopic study of LED and other optical filters. PMT detectors typically offer much higher sensitivity to low light levels than silicon photo diode and are well suitable for Raman spectrum, fluorescence, bioluminescence and chemiluminescence.
