Abstract: A lens according to an embodiment of the present invention may include a first depression and a second depression having predetermined patterns in a lower portion of the lens, and a phosphor layer and the lens may be collectively formed by disposing the lens after spraying a phosphor rather than separately forming the phosphor on the LED chip during a manufacture of the LED module. Accordingly, a production tolerance, and the like of an LED module may be removed to improve yield, and a manufacturing process of the LED module may be simplified. A lens may have an upper portion formed in advance in one of a hemispherical shape, an oval shape, and a batwing shape having a concave central portion, thereby implementing a customized lens according to a predetermined application.

Abstract: Disclosed herein is an apparatus for measuring sub-resonance, which is capable of simultaneously measuring the fundamental frequency characteristics and displacements of an optical pickup actuator through the use of a very simple interferometer. The sub-resonance measuring apparatus of the present invention includes a laser light source, a beam splitter, and an optical detection element. The beam splitter splits light emitted from the laser light source into two light beams. The beam splitter has a reference surface that allows a part of a first beam of the two light beams to be reflected inside of the reference surface and allows the remaining part thereof to pass through the reference surface, and a diffused surface that allows a second beam of the two light beams to be dispersed thereon.
