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.

*Engineered to have the same optical characteristics as our previous RL1660.

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 have the same optical characteristics as our previous RL1660.
