Advanced Illumination - RL121 Small High Dispersion Bright Field
- 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.
