About this system
Semray UV4203 is a modular plug-and-play UV-LED curing system whose smart lamps comprise one or more UV-LED segments on a backplane per curing width, connected by one data and one power cable per backplane. Modules are easily swapped for different wavelengths (365/385/395/405 nm) and placed side-by-side to set curing width, with dimming from 20-100%. Peak irradiance at the emission window is 16 W/cm² (395/405 nm), >90% uniformity even at 20 mm working distance, ~15,000 h typical life with replaceable LED engines.

Plan with Simulex
Will it cure your part?
Simulate the curing dose, working distance and illuminated area for your substrate before you buy — see whether a lamp delivers enough energy across your surface.
