PURPOSE: An optical device for an ultraviolet hardener is provided to minimize a light loss rate by improving an incidence probability of direct light to a lens part. CONSTITUTION: An optical device(1) comprises a main body(10), a light source(20), a total reflection lens(30), and a lens unit(40). The main body comprises an upper body in a trapezoidal shape and a lower body, which connects an end of the upper body and includes an aperture formed in one side. Multiple light sources are each installed on each surface of multiple inner surfaces of the upper body. The total reflection lens is installed in a space formed between the upper body and the lower body. The total reflection lens totally reflects incident light to perpendicularly output the light through the aperture. The lens unit is installed at one side of the main body in which the aperture is formed. |
