COBRA™ Linescan Illuminator Key Features • High level of uniformity due to chip-on-board LED fabrication • Intensity adjustment and On/ Off control • 125mm, 250mm and 500mm • Available in red, IR, blue, UV, white and other wavelengths High-brightness illumination for linescan and web inspection. The COBRA Linescan Illuminator has been designed “from the chip up” for the extreme requirements of high-speed linescan and web • Backlight and frontlight configurations available Key Applications Web and linescan inspection of: • Plastic film and fluorescent line illumination, while offering all of the many advantages of LEDs — long lifetime, controllability, and increased • Flat panel displays Intense optical output is achieved by means of ProPhotonix inspection. Producing an illuminance of up to 220,000 lux, the LED-based COBRA lines are comparable to, or outperform, halogen specially designed high density chip-on-board LED array, a unique • Power Supplies innovation in thermal and optical efficiency for LED arrays. The • External Control Unit chip-on-board approach to LED module fabrication yields an essentially unbroken line of semiconductor light source, resulting in an extremely high level of uniformity. The combination of high intensity and superior uniformity results in crystal clear linescan images.

Spectral Characteristics Colour UV Blue Red IR White Maximum Irradiance and Illuminance** - COBRA Line Relative Intensity and Line Thickness vs. Working Distance Figure 1 - These graphs show illumination line thickness and intensity in the field of illumination, as a function of a working distance. The maximum intensities for each COBRA color are given in the data tables. Intensity measurements were taken using a detector with a 4 mm diameter aperture. The information presented above is for COBRAs in the frontlight * All illuminance and irradiance values are shown for the 125 mm units. The...

DC Electrical Power Requirements*** Power Supplies External Control Unit Current regulation electronics are incorporated inside the COBRA Linescan units. A convenient, cost-effective means of powering the devices is to use ProPhotonix standard 24 V COBRA power supplies. These supplies are mountable on DIN rail TS35/7.5 or 15. An external control unit (ECU) is available as an accessory for use with the COBRA Linescan Illuminators. ProPhotonix ECU offers the following convenient features: • Brightness control dial • On/off switch • LED indicators (power, connection status and thermal...
