Principle

Light from a tungsten halogen lamp is focussed on to the entrance slit of a monochromator. The incident beam of light gets tuned to the desired wavelength by the rotation of a diffraction grating & reflecting optics in Czerny Turner mount and emerges as a monochromatic light from the exit slit of the monochromator. Transmitted portion of this monochromatic light through the medium (Blank, Standard or Sample) is detected by a silicon photodiode. The detected output is processed and % Transmittance / Concentration of the medium is displayed on the readout of the instrument, as selected.

This SCANNING MINI SPEC is a NUV-VIS NIR SPECTROPHOTOMETER with Czerny Turner monochromator and ergonomically engineered into an instrument of convenient size and contemporary style. This instrument is incorporated with microprocessor control of wavelength drive, data processing can be incorporated facilitating spectral scanning.
