"More is better – When using dark field illumination this is usually the case. With up to 3.5 mega Lux even smallest surface faults will be visible."

Martin Merkler, Product Manager Corona Illuminations

Dark field illumination

Chromasens developed a technology to focus LEDs by using elliptical reflectors instead of using lenses. The patented reflector technology will offer a unique quality for imaging and advantages for the customer:

  • No color aberration
  • Higher efficiency compared to lenses
  • High power at longer working distances

Four different types of focus will cover the whole range of working distances needed for machine vision applications.

60 mm “A”

95 mm “B”

190 mm “C”

Parallel “D”

Recommended working distances

50 to 70 mm

70 to 120 mm

120 to 300 mm

> 300 mm
