The DF241 is characterized as a Small 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 with a low-angle dark field illuminator.
With a light intensity of 24kLux at a working distance of ½” (12.5mm), the DF241 is perfect for imaging problems limited to a small field of view.
A 25mm field of view is standard with an optional field of view of 35mm.
Available in a range of wavelengths from UV to IR.
*Engineered to provide the same optical characteristics as our legacy RL1360.
