The RL1660 is characterized as a Large Low Angle Dark Field ring light.

Precisely aimed LEDs provide a very low angle of incidence, radial illumination pattern.

The RL1660 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 2.5kLux at a working distance of 1” (25mm), the RL1660 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.

Change Notification Summary

In an effort to improve our products, Advanced illumination (Ai) will replace the existing dark field rign light designs (RL1360 and RL1660) with the DF241 and DF242. Customers may still buy the old designs up to June 30th of 2019. After that time, only the new DF241 and DF242 will be available. The new dark field ring lights are expected to be released in the 3rd quarter of 2018. These new designs utilize the same LED geometry but with more industrial look. The mounting hole positions will be moving to facilitate this design change.

Please contact your Ai Sales Representative if you have any questions.
