ESL-200-UV LED Stroboscope

ESL-200-UV is a battery operated, UV LED stroboscope designed to inspect security print elements using UV-visible ink. The ESL-200-UV features a six 390nm UV LED array, 9 flash rate memory and rechargeable battery. The ESL-200-UV LED Stroboscope is compact and fits in a pocket.

Adjustable Flash Duration

ESL-200-UV features adjustable flash duration. For most applications standard flash duration works without adjustment. For ultra high speed applications, objects may move during the brief period of a single flash, resulting in a blurred image. By decreasing flash duration, objects have less time to move and the image appears sharper.

Optional ET-1 External Trigger Kit

The external trigger immediately synchronizes the strobe with a rotating object. The sensor is aimed at a ferrous target mounted on the drive shaft and triggers the strobe to flash each time the target passes the sensor. ET-1 is complete with sensor, cables and AC adapter. Ferrous target not-included.

What’s Included in the LED Stroboscope Kit

All stroboscopes come with a 3-Point Calibration Certificate traceable to NIST. The ESL-200-UV stroboscope is sold as a kit and made in the USA. The standard model includes the stroboscope, AC Adapter/charger and plastic carrying case.
