CM-3700A Konica Minolta Spectrophotometer

 

Spectrophotometer (spectral / side port)

The d / 8 optical system (diffuse illumination 8 ° light reception) based on ISO, DIN, and JIS has a variety of measurement functions and is suitable for various applications.

Product introduction Konica Minolta flagship products:
Maintains high accuracy and excellent repeatability even at low reflectance / transmittance
"The most advanced" reference spectrophotometer for the highest level of accuracy and reliability in a color management network system.
With the CM-3700A, Konica Minolta has once again proven its position as a leader in optical technology in the field of "most advanced" instruments. The CM-3700A is designed to achieve the highest performance of accurate color control in all aspects. The manufacturing of large integrating spheres, escutcheons, and the entire optical system is constantly improving, and even exceeds the requirements of CIE, ISO, ASTM, DIN, JIS and other international standards.
Two flat holographic gratings and silicon photodiode arrays for samples, feedback channels and high-power xenon arc lamps, respectively, ensure the highest absolute accuracy and repeatability (especially dark tones).
The advantages of CM-3700A have been appreciated by world-class institutions and industry-leading companies. Another example of Konica Minolta's high-end manufacturing technology is its industry-leading instrument error.

 

Product Overview

 

Measurement of reflection color

  • Choice of SCI or SCE measurement methods
    The measurement method of SCI (including specular reflection light) can minimize the influence of the condition of the sample surface on the measurement data, which is especially suitable for color matching applications. The measurement method of SCE (Excluding Specular Reflection Light) is closer to professional visual evaluation.
  • Variable measurement area According to your needs, you can choose 3 types of measurement areas, the diameters are Ø25.4 mm, Ø8 mm, and 3 mm × 5 mm.
  • Variable UV content When measuring samples containing fluorescent materials (such as paper, pulp), you can control the 1000-level UV component in the illumination light source.

 

 

 

The main purpose

Suitable for plastic, fiber, dyeing, ceramics and other fields

Main features

*
The CM-3700A is controlled by a computer.
Can be controlled with SpetraMagic ™ NX software.
  • The lighting / receiving system conforms to the d / 8 (diffuse lighting, 8-degree reception) optical structure of CIE, ISO, ASTM, DIN and JIS, and the transmission structure of CIE, ASTM, DIN and JIS.
  • The pulsed xenon light source has high brightness, good stability, long life, and shows excellent repeatability when measuring dark and highly saturated colors.
  • The 6-inch integrating sphere has a high-tech coating and has good optical characteristics to make the lighting more uniform.
  • The dual-beam feedback system monitors and automatically compensates the energy of the light reflected by the illumination source through the sensor, which can reduce measurement errors caused by changes in brightness or spectral characteristics.
  • Beamsplitter
    Holographic gratings are more effective at distinguishing between different wavelengths of light, resulting in better repeatability when measuring dark objects.
    Silicon photodiode sensor arrays can quickly convert optical signals into electrical signals. These components are mounted on stainless steel with a low thermal expansion index to ensure long-term stability.
  • The optical structure for sample measurement and light source monitoring is mounted on an aluminum alloy block , which also improves stability.
