4" LED Ring Light 880nm with Barrel Mount

Product Family Description

• 4" Working Distance
• Provides 1.7" Coverage
• Variable Intensity and Strobed Options

Advanced Illumination Standard Working Distance LED Ring Lights are designed to be mounted on the front of many standard imaging lenses using our Ring Light Filter Thread Adapters. Mounting brackets are included for easy system integration. LED intensity can be varied using the in line potentiometer.

Note: Required 24V power supply #66-855. Manual Intensity Adjustment #86-887 and #89-555 are optional and sold separately (not compatible with 85mm diameter models) – these are potentiometers and may not provide the appropriate level of intensity control for low current LED lights.

The strobed models' flash duration is dependent on a trigger signal or potentiometer setting. The duration of the strobe can be adjusted from 30 - 300μs via a knob located in the back of the unit. Trigger input signal is CMOS/TTL compatible. The maximum trigger frequency is 30Hz.
