specbos 3001

specbos 3001 (download datasheet (172kB)) is an easy to use instrument for spectral transmission measurement in the VIS region. It is especially suited for test cells of up to 10 mm optical path length and for flat materials like optical filters.
The software package allows the measurement of spectral data as transmission and absorbance. Besides the display and management of spectra (hot links to Excel and ASCII files) further mathematical operations as first and second derivation are possible.
The optional software JETI specbos color allows the measurement of color coordinates of samples (e.g. L*a*b*).
