RL3940: Classic Low Power Dark Field Ring Light

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.

 

FULL DESCRIPTION

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.
