This spot cure series LED type has over 30 years of actual results. By taking advantage of our optical technology developed up to now, we provide solutions to problems that could not be solved with conventional LED types. We propose products tailored to your needs.

Adopts a fiber light source system
Adopting fiber allows the LED element to be incorporated in the main unit. By always maintaining the optimal LED lighting environment, the LED's inherent long life and highly stable irradiation are retained.
No heatsink needed
Because there is no LED element at the irradiating head, the heatsink required by convention LED irradiation systems has been eliminated. This spectacularly improves usability in confined spaces.
Achieves high output
The proprietary optical system design and adoption of highly efficient liquid fiber enables LED output to irradiate the work surface without waste. The output power bottleneck characteristic of conventional fiber is resolved.
Individually controllable
The irradiation pattern of each fiber can be individually controlled, along with fine settings such as on/off timing and irradiation time.

Installed light source

Does use require light blocking?

Be sure to use ONLY with light blocking. Light leaking from the irradiation aperture can cause eye injury or skin damage in a very short time. When working in the vicinity of unshielded light, be sure to wear eye protection and make sure that the skin is not exposed. Never look directly at the light.
