High Intensity Air Cooled Lighting

The VLX1 series air cooled LED Line Lights provide very bright, uniform lighting focused to a narrow beam, and are ideally suited to Web Inspection and Surface Inspection linescan illumination applications. The limiting factor in many Line Scan systems is the intensity of the Line Light being used. Using the high brightness VLX1 LED lighting the Line Scan acquisition can run faster therefore allowing higher production speeds and/or higher resolution images.

"All in One Design" with Remote Control

The VLX1 also gives you the ability to profile the light; along its length the LEDs are controlled in sections which you have complete control over (via an RS232 interface). If your application requires flat field correction, you can increase the light intensity at each end of the light offering you true flat field correction rather than compromising with software adjustment.

Flexible Working Distance

There are two options for the optics; short working distance optics (37mm) or long working distance (adjustable between 90-150mm) which will give you a highly homogeneous line 3mm wide at the subject. For highly reflective or specular surfaces, an additional holographic diffuser film can be added to the optics to further enhance line profile.

Lengths and Wavelengths

The VLX1 range of high intensity LED Line lights is available in a standard range of lengths and wavelengths, and is compatible with Line Scan cameras such as Basler, Dalsa and E2V. If your application requires something outside these standards, please contact Drew Lear as we also manufacture custom lights to match specific application requirements.
