Flagship spectrophotometer for maximum performance in colour measurement

Proof of Konica Minolta’s leadership in advanced optical technology, a true "State of the Art" instrument. In every detail and without compromise, the CM-3700A is designed for maximum performance making it an ideal choice for a reference instrument in a global colour management network. The CM-3700A allows colour measurement of solid, translucent and transparent samples in reflectance and transmittance.

The optical system is designed and manufactured without compromise, exceeding the requirements of international standards while offering superior levels of inter-instrument agreement.

The superiority of the CM-3700A in terms of absolute accuracy and long term stability, especially on very dark or high chromaticity colours, has been recognised by top ranking institutes and leading companies throughout the colour industry.

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.
