High precision newly launched desktop spectrophotometer CM-3700A Plus

Konica Minolta releases flagship spectrophotometer CM-3700A Plus，Assist the manufacturing industry in providing accurate color measurement solutions

（2024On December 20th, Shanghai, Konica Minolta Co., Ltd. (hereinafter referred to as "Konica Minolta") announced that the company will launch its flagship spectrophotometer CM-3700A Plus (hereinafter referred to as "CM-3700A Plus").

For a long time, Konica Minolta's star product CM-3700A 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 with the previous generation model, the CM-3700A Plus is equipped with an easy to locate camera viewfinder and new features that can synchronously measure sample color and temperature, achieving stricter color management. Given that the CM-3700A Plus will be used as a reference standard instrument for color management, its design ensures high compatibility with previous models and uses highly durable components to consistently output reliable measurement values, thereby helping to improve product quality.

high-precision measurement

In practical measurements, black is often a color that is extremely difficult to achieve high-precision measurement, and the CM-3700A Plus has significantly improved the repeatability accuracy of black measurement * 1. The reason for this is that the difference in measurement values between CM-3700A Plus instruments is small (i.e., the instrument to instrument difference is small), and the Δ E * ab value is 0.08 or below * 2. Therefore, when using multiple instruments or instruments in multiple locations throughout the supply chain, the CM-3700A Plus has more advantages. 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. By using a stainless steel protective shell for the core spectroscopic device, the CM-3700A Plus not only reduces the impact of temperature changes on equipment accuracy, but also delays the aging of components used for a long time.

Improve operability and convenience

The CM-3700A Plus is equipped with an electronic viewfinder, a new feature that allows users to easily locate 3 test objects 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.

Highly reliable features and software

(1) Higher measurement efficiency and color management

Compared to its predecessor, the CM-3700A Plus can simultaneously measure SCI and SCE * 4, 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 * 5 while performing color measurements.

(2) Anxin Service

The CM-3700A Plus is manufactured in Japan and strictly follows a unified quality control system. It is worth mentioning that it is also equipped with WAA (Wavelength Analysis and Adjustment) function to compensate for the wavelength shift of measurement values caused by external factors, including impacts and environmental temperature changes during use. Combined with annual calibration and maintenance, it can provide a guarantee of high precision.

(3) Using SpectraMagic NX2 color data software for color data management

SpectraMagic NX2 * 6 color data software can achieve color management and data classification through various color indices and charts, and communicate with business partners using color values. In addition, with a Ver. 1.4 or higher premium license, users can also utilize the newly added daily check application feature to monitor the status of the instrument.

In the future, Konica Minolta will continue to provide professional and high value-added measuring instruments and solutions, constantly break through innovation, iterate its own products, empower industry users with innovative digital technology, and actively create new commercial value!

About Konica Minolta Metrology Division

Konica Minolta's metrology business is based on the optical technology developed in its front camera business, and has continuously improved since then, providing various products and solutions in the fields of light source color measurement and object color measurement. The products and solutions provided by Konica Minolta help ensure the quality of customers' production sites and improve productivity, with many products being used as de facto standard color measuring instruments.

Konica Minolta actively invests to enhance its competitiveness. In 2012, the company acquired Instrument Systems GmbH (Germany), a company that develops high-precision optical measurement instruments and has outstanding performance in high-performance measurement of display screens and LED lighting equipment. In 2015, the company acquired Radiant Vision Systems, LLC (USA), which specializes in high-resolution 2D measurement instruments for display screens, image processing software, and automatic appearance inspection systems. In 2019, the company acquired EINES SYSTEMS, S.L.U. (Spain) in the field of automotive visual inspection. In 2020, the company acquired Specim, Spectral Imaging Ltd. (Finland), a leading company in the field of hyperspectral imaging (HSI * 7).

In the industrial business field, including metrology, Konica Minolta combines development, manufacturing, and customer service, leveraging core technologies to establish strong relationships with customers and create value together. The company has identified "display screens," "mobile," and "semiconductor manufacturing" as key areas of focus for the future, and has made strategic investments in strengthening businesses such as sensing, high-performance materials, inkjet (IJ) components, and optical components (industrial applications) to promote business development that is more closely related to customers' manufacturing value chains.

*1: Repeatability refers to the measurement error when the same sample is measured multiple times under the same conditions. It is an indicator of measuring accuracy. The lower the value, the higher the reliability of the measured value.
*2: The average of the measured values of 12 BCRA Series II color blocks.
*3: If you need to connect to a computer, you need to purchase SpectraMagic NX2 Ver. 1.5 software separately.
*4: SCI: Abbreviation for Specular Component Included. In this measurement method, specular reflection light is included in diffuse reflection light. Regardless of the surface condition, the color of the material can be evaluated. SCE: Abbreviation for Specular Component Excluded (excluding specular reflection). In this measurement method, only diffuse reflection light is measured. The evaluated color is closer to the color observed visually.
*5: The sample temperature can only be measured during reflection measurement.
*6: SpectraMagic NX2 is a separately sold software.
*7: HSI is a method of identifying substances in a certain area using a camera with a narrow bandwidth in the visible to mid infrared wavelength range. It is expected to be used in fields such as recycling, material/resource identification, food analysis, environmental safety, and product surface condition analysis.
