Spectrophotometer

Holmarc HO-SP-3480 & HO-SP-1911 are entry level spectrophotometers suitable for education, research and industrial applications. Unlike other entry level spectrophotometers, it employs the classic Czerny - Turner monochromator design, normally available only with advanced models, which ensures low stray light. It uses 1200 lines/mm blazed holographic grating as the dispersion element providing high wavelength resolution. It also employs a sigma delta ADC of 16 bit resolution for photometric measurement, a resolution higher than most of the spectrophotometers available in this price range. A Graphics LCD screen is used to plot an absorbance v/s wavelength graph. The data can then be analyzed for peaks and valleys.
