Electronic design and manufacturing services provider MAZeT GmbH presents a number of new JENCOLOR products for measuring tasks in the fields of colorimetry and LED light. The new products include the MTCSiCF color sensor for photometry and colorimetry, the MCDC04 sensor signal amplifier with an I²C interface and the MTCS-INT-AB3 sensor board for light applications. The JENCOLOR color sensors in conjunction with the signal ICs are suited to the temperature and long-term stabilization of LED light, colorimetry tasks in industry, medicine and cosmetics, and also analytics applications.

The JENCOLOR color sensor MTCSiCF in its space-saving QFN16 housing (4 x 4 x 0.9 mm) is the latest member of the true color sensors family with XYZ filters designed for eye-precise, absolute colorimetry and feature defined filter characteristics (standard spectral value function). The sensor allows for the precise measurement of the color of materials, liquids or light in accordance with CIE1931/DIN5033. This facilitates measuring systems that replicate human color perception and which display their results as XYZ points in the Lab (Luv) color space. The sensors are suited to all applications that require an optimum ratio between price, overall size and colorimetry precision. At the same time, the human eye is used as the quality standard for the precision of color determination and colorimetry.

For the signal input level, photometry requires a further dynamic range that can comprise several dimensions. The MCDC04 meets these requirements with its internal signal processing concept. The programmable signal conditioner IC facilitates an input signal resolution of up to 16 Bit and ensures a high synchronization of the channels across the working temperature range. The MCDC04 signal conditioner is specifically coordinated to the requirements of the tristimulus JENCOLOR color sensors. The combination of the MTCSiCF color sensor with the MCDC04 is excellently suited for many photometry and light control applications.

The MTCS-INT-AB3 evaluation kit is based on two ASSPs, which have been specially developed for tasks in LED light control, e.g. the regulation of LED light sources. The MTCSiCF true color sensor implements colorimetry in accordance with the CIE1931 standard. The MCDC04 signal conditioner IC is an analog-digital converter with electricity input, a high bandwidth and I2C output. Both components are supplemented by the power supply. With this functionality the board is suited for OEM color sensor solutions in the Luv/Lav color space. The precision of the photo colorimetry and long-term stabilization of the sensor characteristics contribute to securing the color stability of LED
