Advanced Illumination - RL3940 Folded Beam Dark Field
- The RL3940 is characterized as a Folded Beam Dark Field ring light.
- Precisely aimed LEDs, along with an aluminum beam folder, provide a specific and repeatable light pattern on the imaging plane.
- The light provides up to 11kLux at a working distance of .6” (15mm).
- The RL3940 is available in a wide range of wavelengths from UV to IR.
- The folded-beam configuration provides dark field illumination in a compact 3.9” (100mm) housing.
- The housing’s large inner diameter can accommodate lenses up to 55mm in diameter.
- The light can also be ordered with an optional mounting ring.
