• 0 – 100% intensity control 
• For use with lights built with an ICS 2 after 3/1/2012 
• NOT COMPATIBLE with LLI37, BLI38, LLI67, and BLI68 “IC” Lights

• 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 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.

• Eliminating all but a narrow band of light (+/- 40nm) centered on the specified wavelength, band pass filters are used to enhance colors, or to stop unwanted ambient light from reaching the camera. 
• Filtering can replace existing shrouds, simplifying the physical set up of an inspection site. 
• Ai offers 660nm and 635nm band pass filters to fit a number of different lens sizes.

• The RL2316 is characterized as a Compact Aimed Bright Field ring light. 
• Precisely aimed LEDs provide a level of lighting control not found in traditional illuminators. 
• A range of standoffs and fields of view may be specified at the time of order. 
• The ring light is available in a wide range of wavelengths from UV to IR. 
• Diffuser and polarizer options are also available. 
• With its compact form factor, the RL2316 is ideal for the inspection of smaller, non-specular objects and where space for the illuminator is limited.

• Our Standard Intensity Linear Backlights provide rugged construction for demanding environments. 
• Standard intensity illumination with low power input requirements. 
• Multiple wavelengths available with very consistent illumination over the entire active area. 
• Available in 1” (25mm) increments with lengths up to 80.5” (2044mm).

• 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.
