Large Low Angle Dark Field

The DF242 is characterized as a Large Low Angle Dark Field ring light.  Precisely aimed LEDs provide a very low angle of incidence, radial illumination pattern.  A scratch on a sheet of glass is a good example of a defect that can be detected easily with a low-angle dark field illuminator.  With a light intensity of 24kLux at a working distance of 1” (25mm), the DF242 is perfect for imaging problems with medium sized fields of view.  A 35mm field of view is standard with optional fields of view of 45 and 70mm.  Available in a range of wavelengths from UV to IR.

*Engineered to provide comparable optical characteristics to our previous RL1660.
