Spectrophotometer Calibration Filters

UNICO

Spectrophotometer calibration filters are used to calibrate wavelength accuracy, various transmittance or absorbance values as well as the stray light of the instrument. UNICO filters are mounted in the black anodized aluminum holders and have the same external dimensions as standard 10mm square cuvettes. This design assures compatibility with all instruments manufactured by UNICO as well as other major brands. UNICO glass filters are factory certified, a calibration certificate is included with each set. NIST traceable filter options are available
