Advanced Illumination - DF241 Small Low Angle Dark Field
- 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 comparable optical characteristics to our previous RL1360.
