DF242 Series
Large Low-Angle Dark Field Light
The DF242 is a Large Low Angle Dark Field ring light. engineered as a replacement for the previous Dark Field Series RL1660. Precisely aimed LEDs provide a very low angle of incidence, radial illumination pattern. A scratch on a sheet of glass is an example of a defect that can be detected with a low-angle dark field illuminator.
With a light intensity of 24 kLux at a working distance of 1” , the DF242 is perfect for imaging applications limited to a moderate field of view. A 35mm field of view is standard, with options of fields of view of 45 mm and 70 mm.
