This VISIBLE SPECTROPHOTOMETER(MINI SPEC) is a NUV-VIS NIR SPECTROPHOTOMETER with Czerny Turner monochromator, two cell sample holder ergonomically engineered into an instrument of convenient size and contemporary style. This instrument is incorporated with simple push/pull selection of sample holder, circular filter disk and push button selection of output to facilitate quicker calibration and measurement turn-out.


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 manual slewing 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 the Percentage Transmittance / Absorbance / Concentration of this medium is displayed on the readout of the instrument, as selected.
