The Lightning-cure LC-L3, a UV spot light source introduced by Hamamatsu Corp., features nine UV LEDs that emit at 365 or 385 nm, depending upon the model. It delivers intensity of 250 mW/cm2 at 365 nm and 325 mW/cm2 at 385 nm, and uniform light level output throughout the LEDs’ 20,000-h lifetime. On/off switching and light-level adjustment can be controlled on each LED, enabling creation of tailored irradiation profiles. Up to 16 steps can be input into a program. The light source is suitable for UV adhesive curing, UV ink drying, semiconductor and liquid crystal exposure, and high-resolution optical microscopes. The unit monitors the temperature inside the head to control and maintain light intensity at a constant level, eliminating the need for daily light-level checks.
