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 can further condition the light output. The RL121 delivers 27kLux at a working distance of 50mm.
