LINEAR IRRADIATION TYPE UV-LED UNIT
Stable output accuracy
Advance heat-dissipation technology is yet another in a long string of
UV-LED successes from Hamamatsu. This technology delivers stable ir-
radiation that suppresses heat drift to an absolute minimum by a cooling
technique that ensures both ample light intensity and long service life.
Long service life and huge cut in running costs.
A great feature of LED type UV lamps is their super long service life
compared to ordinary UV lamps. These UV lamps only need to turn
on momentarily unlike other lamps which are ON most of the time.
This smaller ON time makes a huge difference in actual service life!

Uniform UV irradiation over a wide range
Our uniquely designed optical systems are what make super-uniform UV irradiation possible over a wide range with minimal variations in light in-
tensity (these can replace UV ovens). Uniform UV irradiation supports quality control by minimizing uneven drying of printed items and warping
from adhesive hardening.
