CM-3700A Plus spectrophotometer

For a long time, Konica Minolta's star productsCM-3700A Plus spectrophotometerIt has been widely used and highly praised as a reference standard instrument for object color measurement by many companies around the world.

As an iterative upgrade of the CM-3700A, the CM-3700A Plus not only inherits the high precision and reliability of its predecessor, but also relies on Konica Minolta's optical technology to further improve measurement accuracy. It can be widely used in multiple industries that require color measurement and management, including automotive, electrical equipment, smartphones, cosmetics, coatings, plastics, building materials, and textiles, including quality control, production, and research and development, providing strong support for the manufacturing industry to achieve more accurate color measurement.

Compared to the previous product CM-3700A, the new CM-3700A Plus significantly improves the inter instrument difference, ensuring more accurate color measurement. For materials containing fluorescent whitening agents, such as paper and pulp, by adjusting the UV cut-off filter, the instrument can perform more accurate measurement work.

Focus on stability

The optical system is made of stainless steel material, which has a low coefficient of thermal expansion, significantly improving the durability and long-term stability of the instrument.

Relying on independently developed sulfuric acid Barium coating ensures measurement reliability

Konica Minolta utilizes * technology and independently develops coating methods by using sulfuric acid Barium effectively stabilizes the diffuse illumination and reflection characteristics inside the integrating sphere, ensuring the reliability of measurement results.

High repeatability accuracy in measuring black and dark samples

CM-3700A Plus spectrophotometerCan evaluate samples with low reflectivity with higher accuracy. Compared to its predecessor, the measurement repeatability of the black sample has been significantly improved.

Small repeatability and inter device differences, with better data compatibility

In practical measurements, black is often a color that is extremely difficult to achieve high-precision measurement, while the CM-3700A Plus has significantly improved the repeatability accuracy of black measurement. The reason is that the instrument to instrument difference between CM-3700A Plus instruments is small, and the Δ E * ab value is 0.08 or below, which can ensure more reliable and accurate color management between multiple devices in different factories in the supply chain. In addition, the CM-3700A Plus is also compatible with the data of the previous generation model CM-3700A and can continue to use the previously accumulated measurement data.

Higher measurement efficiency and * color management

Compared to its predecessor, the CM-3700A Plus can measure both SCI and SCE simultaneously, reducing measurement time by almost half and achieving higher measurement efficiency. In addition, the CM-3700A Plus is equipped with an environmental temperature and humidity meter and a sample thermometer, which can check and record the temperature and humidity of the measurement environment and the surface temperature of the sample while performing color measurements.

Improve operability and convenience

The CM-3700A Plus is equipped with an electronic viewfinder, a new feature that allows users to easily locate objects under test on their computer monitor. The image can be saved together with the measurement data and the measurement position can be checked on the image. In addition, the CM-3700A Plus is equipped with a wider transmission cavity for easy placement and retrieval of test samples, and provides accessory storage space for a more user-friendly design.

Instrument performance with high reliability

Wavelength Analysis and Adjustment (WAA) is a part of regular calibration services and a new technology from Konica Minolta that ensures the stability and reliability of the instrument before the next calibration.

Color management software SpectraMagic NX2 (optional accessory)

SpectraMagic NX2 is a color management software that provides users with customizable screen displays and a wide range of features for operating and transmitting data between spectrophotometers and computers, as well as conducting in-depth analysis. This software allows users to display a list of data and generate color differences and spectra, enabling effective color management decisions based on various values and indicators.
