Features

The flagship spectrophotometer from Konica Minolta, meeting the highest expectations in absolute accuracy, short- and long-term stability and unsurpassed inter instrument agreement levels to act as reference instrument in a global colorimetric network.

Built without compromise:

Two flat holographic gratings with silicon photodiode arrays, one each for the sample and feedback channel, together with the high power xenon flash ensures highest absolute accuracy and repeatability.

Eliminates temperature drift:

The entire optical system is mounted on a stainless steel casted chassis to resist even small changes in allignment caused by changes in ambinet temperature.

Motorized gloss trap:

Measurements of samples with (Specular component included - SCI) and without ( Specular component excluded - SCE) surface conditions.

Motorised UV cut filter:

Exclude the impact of any optical brightening agents (OBA) in samples such as textiles, pulp and paper.

Transmittance Zero Calibration plate CM-A100

The Transmission Zero Calibration Plate CM-A100 is required to block the light path for zero calibration in transmittance measurement mode. The black and mat coating of the plate absorbs also stray light within the transmission chamber of the instrument.
