With a 150 x 100 mm emitting area, LS-BKL-1542 sits in the lower half of the 14 sizes of this backlight series: a smaller emitting area than most of the series, for smaller parts and tighter spaces (for fields of view up to about 150 x 100 mm).
LS-BKL-1542: luminous size 150 x 100 mm, overall H 20 mm, power R 11 W.
Parallel backlight with high-density LEDs distributed across the bottom; special optical material and a simple structure eliminate shadows, for high-precision dimension measurement.
