Large Low Angle Dark Field

DF242

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 provide comparable optical characteristics to our previous RL1660.

Full Description

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 provide comparable optical characteristics to our previous RL1660.

Change Notice

PCN No: 166

Date Issued: May 5, 2023
Notice Type: Product Change
Product Type: 660nm Wavelength on traditional 5mm Lights Discontinuation

Change Notification Summary

Advanced illumination (Ai) will be ending the manufacture of the 660nm color option on our classic aimed lights due to the LEDs being discontinued from the manufacturer. We expect to have six months of inventory to fulfill orders, after that we suggest purchasing the same light but with the 625nm wavelength.

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