CM-3500d Spectrophotometer (spectral type, top port)


Made in Japan



A multi-function Spectrophotometer for virtually any Application

A Multi-Function Top-Port Spectrophotometer suitable for virtually any application.

The Konica Minolta CM-3500d Spectrophotometer is a highly accurate d/8??geometry, top-port instrument designed for a broad range of color measurement applications. Control is performed via computer software SpectraMagic NX to provide simple, efficient colour control from the research laboratory to the factory floor.

The CM-3500d offers both reflectance and transmittance measurements. Changeable measuring aperture mask with 3, 8 and 30mm diameter and a special mask for a Petri Dish offer maximum flexibility for all kind of samples.

The top-port design allows specimens to be simply placed on top of the unit, making it easy to measure the reflectance of not only solids but also granular, powders, pastes or even opaque liquids.

Transparent liquids or solids can be measured in the transmission chamber.


Product Overview

Reflective Color Measurement

  • SCI/SCE Switching
    When SCI is selected, measurements will be unaffected by the specimen surface condition, and this is ideal for the control of color compounding ratios and CCM. Alternatively, SCE can be selected to obtain test measurements for conditions approximating visual examination by eliminating specularly reflected light. r
  • Measurement Diameter. Switching Measurement diameters of 30mm, 8mm, and 3mm (optional) can be selected according to the specimen being measured. r
  • Powder and paste measurement. An optional Petri Dish Set allows powder and paste specimens to be measured.

Transparent Color Measurement

Measurement of transparent colors is supported by diffuse illumination/0??iewing angle (d/0) geometry. Wide-ranging support is provided for measurement of glass filters and other sheet- or plate-type specimens, in addition to liquid items for food products, cosmetics, etc.

Principal Applications

Medicine and foodstuff industries, etc.
