Chromasens Corona II with cooling options

Chromasens GmbH, a manufacturer of line-scan camera systems for 2D and 3D machine vision applications, has expanded the cooling options for its world-class CORONA II LED Line Scan Lighting to support passive heat sinks, compressed air, liquid cooling, and fan cooling.

As line scan machine vision speeds continue to increase, Mercer said, the illumination also needs to increase in intensity to enable continuous high-quality image acquisition. The more intense the illumination, the hotter the temperatures and the higher the potential for LED failure.

Lumen maintenance of the LED is directly correlated with the temperature of the chip. By keeping the temperature of the CORONA II low, users can achieve an LED lifetime of up to 80,000 hours without reduction of lumens over time. Higher performance of the LED's greatly reduces erroneous fault detection, while increasing the ratio of success while inspecting printed materials, food, steel, semiconductors, and reflective surfaces.

Chromasens offers three passive heat sink options for its CORONA II Dark Field, Bright Field and Tube Light systems in sizes from 10mm x 50mm to 100mm x 50mm. Although passive, the heat sinks allow up to 75% maximum permanent power at 35°C ambient temperature. Two fan coolers are available, along with a water cooling system. Active air flow, compressed air and water cooling are best for measurement applications in high temperature environments. By monitoring the temperature of the LEDs and controlling the cooling, spectral behavior issues can be avoided.
