Abstract
Provided are devices for applying actinic radiation to a curable resin. The devices include a housing having a front face, an actinic radiation source arranged within the housing such that actinic radiation emerges from the housing through the front face, and a proximity detector. The proximity detector is functionally connected to the actinic radiation source such that the actinic radiation source is shut off unless the proximity detector detects the presence of a surface within a safe distance from the front face. Optionally, the device includes a surface temperature sensor functionally connected to the actinic radiation source such that the actinic radiation source is shut off if the surface temperature sensor senses a surface temperature exceeding a maximum safe surface temperature.
