• 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.

• 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 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 RL4260 is characterized as a Medium 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, including a 3 channel RGB version. 
• Diffuser and polarizer options are also available. 
• The large inner diameter of the ring light can accommodate lenses up to 55mm in diameter. 
• The light can also be ordered with an optional mounting ring.

• The RL127 is characterized as a Large High Dispersion Bright Field ring light. 
• Non-lensed LEDs disperse light at broad angles, providing “soft” lighting for applications that require short to medium working distances. 
• The low-profile design is only .75” (19mm) thick, with an O.D. of 4.6” (117mm) and I.D. of 2.61” (66.3mm) allowing it to be used in space constrained applications. 
• The I.D. provides a standard 67mm diameter thread with a pitch of .75mm for further mounting flexibility.
