DL1001B is a 10.1” LCD 405nm backlight module developed for 3D LCD printing with well collimated 405nm UV LEDs array. The designed collimation angle (HWHM) of DL1001B is ±8 degrees, and the minimal irradiance after Mono-LCD is over 4mw/cm2. With good irradiance uniformity, DL1001B can well meet the needs of 3D printing for industrial applications.
