    摘要: According to an embodiment, an IPL sterilization device includes a lamp configured to output light including a visible light region to sterilize a region including a surface of an object; a capacitor configured to transmit a voltage charged to the lamp; and a controller configured to control the capacitor, wherein the controller is configured to: control the lamp to be driven in an outputable state or an unoutputable state, change the lamp to the unoutputable state when the object satisfies an object overheat condition in the outputable state, and change the lamp to the outputable state when the object unsatifies the object overheat condition after the lamp satisfies the object overheat condition and changes the lamp to the unoutputable state, wherein the outputable state is a state in which the lamp is capable of outputting light by applying a driving pulse to the lamp by the capacitor, and the unoutputable state is a state in which the lamp is not capable of outputting light because the capacitor does not output a driving voltage to the lamp.

    摘要: Disclosed is an extended depth-of-focus lens having multiple waveplates. More particularly, the extended depth-of-focus lens having multiple waveplates includes a lens having an incident surface and an opposite surface thereof; a lens waveplate made of a birefringent material, and disposed on the lens in a direction of a central axis of the lens to have phase distribution to increase the number of focal points; and a phase distortion waveplate made of a birefringent material, and disposed on the lens in a direction of a central axis of the lens to have a phase distribution to extend a depth of focus, wherein, in the waveplate layer, phases between neighboring lens waveplates, phases between phase distortion waveplates or phases between a lens waveplate and a phase distortion waveplate have opposite phase signs such that they are in a complementary relation.
