-
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.

More Product Information
-
High dispersion for reflective surfaces and shorter working distances.
-
Provides a wider and more intense illumination area than the AL126.
-
IP65 compliant washdown option is available, as are a wide spectrum of wavelengths.
-
Available with polarization and diffusion light conditioning.
-
This expandable compact bar light is pre-engineered for custom lengths in 2″ increments up to 20″
-
To simplify the mounting process, Ai offers a line of camera brackets for positioning lights under or around the camera lens.
-
Most brackets are designed to be held in place by the same screw that secures the camera.
-
Part of the MicroBrite™ family of high performance, compact machine vision lights.
-
This bar light outperforms the competition with high intensity output of 73 kLux at a working distance of 100mm.
-
Available in a broad range of wavelengths with expandable sizes in 3” (75mm) increments up to 18” (450mm).
-
Complete built-in control for continuous and strobe modes
-
Adaptive Power™, a feature of the EuroBrite™ lighting controller, utilizes an onboard thermistor to maximize light output in continuous mode
-
Adaptive Overdrive,™ another feature of the EuroBrite™ lighting controller, provides a maximal output pulse in strobe mode regardless of the exposure period
-
IP67 sealed enclosure suitable for washdown environments
-
Rugged construction that has been tested to withstand over 1000lb.
-
Industrial grade LEDs providing high-intensity illumination of 45klux (working distance of 200mm)
-
Daisy chain up to 4 for a combined length of 48”
-
Our EuroBrite™ lineup outdoes the competition in so many ways. With more features at a competitive price point, there’s no better value in machine vision lighting:

-
The RL121 is characterized as a Small High Dispersion Bright Field ring light.
-
Non-lensed LEDs disperse light at broad angles, providing “soft” lighting for applications that require short working distances.
-
The low-profile design is only .56” (14.2mm) thick, allowing it to be used in space constrained applications.
-
Optional adapter rings are available for camera lens mounting.
-
A wide variety of wavelengths are available from UV to IR. An optional polarizer and/or diffuser may be used to further condition the light output.
-
The RL121 delivers 27kLux at a working distance of 50mm.
-
The RL113 High Intensity Bright Field ring light offers a very wide array of wavelengths from UV to IR.
-
With intensities of up to 45.5kLux at 12” (300mm), the RL113 is particularly well suited to longer working distances.
-
A rugged, heavy enclosure, compliant with IP67 requirements, is well suited to demanding environments.
