-
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.

-
The IC Inline Controller (ICS 2.0) provides steady and optimal current to lights from a small package when larger, more versatile discrete controllers are not necessary.
-
The IC provides continuous-on and DC gating on/off control as well as 0-10 volt analog dimming.
-
All ICS models employ reverse input polarity protection.

-
Part of the MicroBrite™ family of high performance, compact machine vision lights.
-
Provides diffuse illumination at a low angle to cast shadows used to identify surface defects, embossed text, etc.
-
This ring light is more diffuse and less directional than the DF196.
-
Can be used to produce a bright field effect when the outer diameter is smaller than the working distance.
-
Available in 4 sizes with an intensity of 47klux (working distance of 64mm with DF198-180).
-
The LL158 Series produces an oblique (30°) line of illumination for line scan applications in a passively cooled design.
-
When oriented across a moving web or conveyor line, unlike standard line lights, this linear light’s unique geometry highlights engraved or raised lines that run parallel to the material travel.
-
Provides an intensity level of 53kLux (working distance of 75mm).
-
Pre-engineered for expandability in 6” (152mm) increments up to 90” (2.28m).
-
Available intensity control provides illuminance adjustability for every 6″ increment via a 0 – 10v input.
-
The RL3536 is characterized as an Aimed Dark Field ring light.
-
Precisely aimed LEDs provide a specific and repeatable light pattern on the imaging plane.
-
Provides up to 8.4kLux at a working distance of 3” (76mm).
-
The light is available in a wide range of wavelengths from UV to IR.
-
Diffuser and polarizer options are also available.
-

LL163 derivatives include LL2912 (3”), LL3024 (6”) and LL3148 (12”) (which represent legacy part numbers)
-
The SL223 is characterized as a MicroBrite™ Spot/Coaxial Light and is designed primarily to replace fiber optic light sources in coaxial lensing applications.
-
Optional couplers are available for use with Dolan-Jenner, Fostec, and Moritex fiber bundles.
-
The SL223 is also designed for general lighting purposes where a very intense, miniaturized light source is required. General purpose spot lights may be used to create both dark field and bright field affects, depending on how they are deployed during the inspection.
-
The spot light is designed to provide 8.1kLux at a working distance of 4” (100mm) and is available in a very wide range of wavelengths from UV to IR.
