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 350 to 960nm. 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 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. 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. Results are obtained as spreadsheet.
Heavy duty aluminum 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 application. The basic system and accessories are designed in modular fashion. More and more accessories can be added as the applications expand. |
