Features:

High-speed, high-accuracy measurements
Measurements at wavelengths from 360 to 740nm at 10nm pitch are taken in approximately 0.6 seconds. Minolta's optical technology ensures high absolute-value accuracy and repeatability, and extremely strict quality control provides higher inter-instrument agreement and reliability.
Illumination/viewing geometry- Meets ISO and DIN standards for d/8 (diffuse illumination/8º viewing angle) geometry and also conforms to CIE and ASTM standards for d/0 (diffuse illumination/0º viewing angle) geometry.
Pulsed xenon lamp light source- Provides high stability, long life, and excellent repeatability on dark and high-chroma colors.
6-inch integrating sphere-Has a powdered barium sulfate (BaSO4) coating with superior optical characteristics.
Double-beam feedback system-Monitors the light emitted by the xenon lamp and automatically compensates for changes in brightness or spectral characteristics.
Flat holographic grating-Efficiently separates the light by wavelength to provide higher repeatability for dark colors.
Silicon photodiode array sensor- Quickly converts the light separated by the grating to electrical currents.
Various measuring functions
Switchable between SCI and SCE measurements- SCI (specular component included) measurements minimize the influence of surface conditions on measured values, making it suitable for CCM applications. SCE (specular component excluded) measurements correspond closely to professional visual evaluation.
Changeable measurement areas-Select measurement areas of 3x5mm, ø8mm, or ø25.4mm according to the application.
Variable UV- The amount of UV included in the illumination can be controlled in 1000 steps for measurements of fluorescent materials.
Transmittance measurements-The spectral transmittance of liquids or of specimens in sheet or plate form can be measured using d/0 (diffuse illumination/0º viewing angle) geometry.
CM-3720d(Whiteness Model) / CM-3730d(Paper Industry Model)
UV cutoff filter switching (CM-3720d, CM-3730d) -Cuts off UV components having wavelengths of 420nm or less emitted by the light source. Useful for eliminating the effects of fluorescence when measuring fluorescent materials having excitation wavelengths below 420nm. Enables easy switching to normal measurement using illumination including ultraviolet radiation.
Low-illumination setting (CM-3720d, CM-3730d)- Reduces illumination level to one-fifth. Reduction of light quantity can eliminate triplet influences, which may occur occasionally when measuring fluorescent materials at the normal illumination level.
Opacity Jig (CM-3730d)- Enables easy switching of the background between white and black and ensures paper position does not shift during opacity measurements.

Description

Demands for higher accuracy and more analysis capabilities have been increasing, particularly from R&D professionals. In response, Konica Minolta has utilized its long experience in optics and color measurement to create the CM-3700d, a high-accuracy benchtop spectrophotometer suitable for not only research and development, but also quality control or CCM applications. The CM-3700d has performance that equals or exceeds that of most high-end benchtop spectrophotometers, with 3 measuring areas, motorized variable UV, and Specular Component Included or Excluded. The CM-3700d offers both reflectance and diffuse transmittance measurements at wavelengths from 360 to 740nm at 10nm intervals. It is compact enough to be placed next to a computer, and all functions are controlled by computer via the RS-232C interface, making the CM-3700d easy to integrate into virtually any system.
