摘要:
The camera module disclosed in the embodiment of the invention includes a lens barrel having a through hole therein; and first, second and third lenses coupled to the through hole of the lens barrel and aligned with an optical axis from an object side to a sensor side. The materials of the first and second lenses are different, a refractive index of the second lens is lower than a refractive index of the first lens, the second lens includes a flange portion extending from the optical axis toward an inner surface of the lens barrel, and a length of a first contact surface in which the flange portion of the second lens contacts the inner surface of the lens barrel is 20% to 50% of a thickness of the flange portion. An object-side third surface and a sensor-side fourth surface of the second lens have different radii of curvature on the optical axis, and a center of the first contact surface where the flange portion of the second lens contacts the inner surface of the lens barrel may be located closer to a side having a greater radius of curvature among the third surface and the fourth surface based on a center of the thickness of the flange portion.

A light-emitting apparatus (100A-G) is disclosed. The light-emitting apparatus (100A-G) includes a light source unit (110A-B) for emitting a first excitation light beam (L11), a beam shape conversion unit (130A-B) for reflecting the first excitation light beam (L11) and outputting the reflected first excitation light beam (L11) as a second excitation light beam (L21), and a driving unit (182) for driving the light source unit (110A-B), wherein the beam shape conversion unit (130A-B) includes a plurality of reflective surfaces (131-135, 137) having different reflection patterns, and the reflective surfaces (131-135, 137) are arranged in a direction that intersects the direction in which the first excitation light beam (L11) is incident.

An optical system according to an embodiment includes first to third lenses disposed along an optical axis from an object side to a sensor side direction, wherein the first lens has a meniscus shape convex toward the object side, and satisfies 1.7 ≤ nt_1 ≤ 2.3 and TTL ≤ 6mm. (nt_1 is the refractive index of the first lens with respect to the light of the t-line wavelength band, and TTL is the distance on the optical axis from the object-side surface of the first lens to the upper surface of the image sensor.)
