LED inspection with five channels

Micro-Epsilon offers the new colorCONTROL MFA-5 for the inspection of LEDs starting at a basic version that offers five measuring channels. This simplifies the inspection of LEDs for their function, contrast and luminosity. The new MFA-5 is extremely compact and can verify up to five LEDs simultaneously. The measuring system can be extended in a modular fashion by adding extra MFA-E modules in batches of 5 channels.

The light from the target object is transmitted to the inspection system via a flexible, 2mm diameter, plastic optical fibre and is therefore evaluated dynamically using a colour sensor for colour and intensity. The colour value, which is evaluated within just a few milliseconds, is output as RGB-, HIS or CIE values and then transmitted via USB or RS232 interface at a rate of between 9,600 and 115,200 Baud to a higher level inspection or evaluation system for further processing.

In order to ensure a wide measurement range for intensity (illumination) the sensitivity of the sensor can be adjusted by using two different modes (High Sensitivity Mode and Low Sensitivity Mode). Due to the levels it is possible to recognise LED colours up to +/- 4 nm. The installation of the system colorCONTROL MFA-5 is performed via a test-software, that is included in the scope of delivery. The recognition results are displayed in detail.
