Disclosed is a condenser and a high-and-low-beam integrated vehicle lamp module, the condenser comprises at least one light incident portion, a light-transmitting portion, and a light emergent portion, wherein a 50L dark area light shape forming structure is formed on the light-transmitting portion; the 50L dark area light shape forming structure protrudes from a surface of the light-transmitting portion and has a slope surface; and the distance from the slope surface to the surface of the light-transmitting portion gradually increases from a position close to the light incident portion to the light emergent portion. Since the 50L dark area light shape forming structure protrudes out of the surface of the light-transmitting portion and has the slope surface, in a high-beam illumination mode, some light is emitted from the 50L dark area light shape forming structure to a 50L test point.

A lens includes a cover part and a light-shielding part. The cover part includes a lens part, a connection part extending downward from lateral sides of the lens part, and one or more flange parts each extending outward from a lower-end portion of the connection part. The lens part and the connection part define a recess having an opening facing downward. The flange parts extend outward from a periphery of the opening of the recess. The lens part, the flange parts, and the connection part are formed of a thermosetting first resin and continuous to one another. The light-shielding part covers outer lateral surface of the connection part and is formed of a thermosetting second resin having a greater light-absorptance or a greater light-reflectance than the thermosetting first resin. The flange parts have a greater thickness than the connection part.

The window material for an optical element of the present invention is formed of synthetic quartz glass that is likely to be subjected to shape processing, can be manufactured at low cost, and has a flat plate shape. Even if the window material for an optical element has a flat plate shape, for example, in a window material of a UV-LED such as a UVC-LED sealed with a surface mount package (SMD PKG), light emitted from the optical element, in particular, light having a light distribution angle can be efficiently collected when passing through the window material, and light collection equal to that of a window material having a lens shape such as a conventional convex shape can be achieved. Furthermore, light distribution without irradiation unevenness such as Lambertian reflection can also be achieved.

A lamp for a vehicle includes: a light source configured to emit light; and a reflector configured to receive and reflect the light emitted from the light source. The reflector includes a first reflection surface, and a surface of the first reflection surface has an uneven shape in which a plurality of convex regions and a plurality of concave regions are repeated. A recessed section, which is recessed downward, is formed in each of the convex regions of the uneven shape, and a protrusion section, which protrudes upward, is formed in each of the concave regions of the uneven shape.

According to some aspects, a medical imaging system is provided. The medical imaging system includes an illumination device and a medical imaging device. The illumination device includes a first light source configured to emit first light having a wavelength range. The illumination device further includes a second light source configured to emit second light having at least one predetermined wavelength band. The at least one predetermined wavelength band is within the wavelength range. The illumination device further includes a dichroic mirror configured to attenuate a portion of the wavelength range corresponding to the at least one predetermined wavelength band and to multiplex the second light with the first light such that the portion of the wavelength range of the first light is attenuated. The light multiplexed by the dichroic mirror is emitted from the illumination device along an optical axis and irradiates an observation site. The medical imaging device includes at least one sensor configured to receive light from the observation site.

Integrating rod modules are disclosed comprising a plurality of single and/or solid integrating rods that are mated together by straps. Such modules tend to comprise a greater length than the single and/or solid integrating rods and provide good illumination to a modulator that light from a light source is transmitted through the integrating rod module. The straps may comprise a material (e.g., glass) that has substantially same or similar thermal characteristics as the integrating rods. The straps may be glued to the integrating rods by a glue having a substantially different (e.g., lower) index of refraction than the integrating rods, so as not to disturb the internal reflectance of the rods. The straps may be reinforced by braces that may allow the integrating rod module to be set within a projection display system at an angle substantially different from horizontal.

Provide is a lens which outputs light, emitted by a plurality of light sources, with uniform light distribution. The lens includes a lens body having a first surface which is flat and has an incident hole formed therein, and a second surface which is convex and opposite the first surface; and a plurality of incident surfaces which are recessed from the incident hole toward the second surface, each of the plurality of incident surfaces corresponding to a light source of the plurality of light.

Optical sensors and particularly gimbaled optical sensors transmit an active signal at a given wavelength(s) and receive passive signals over a range of wavelengths and the active signal in a common aperture. The sensor includes a Tx/Rx Aperture Sharing Element (ASE) configured with an annular region that couples an active signal having a ring-shaped energy distribution to the telescope for transmission and a center region that couples the passive emissions and the returned active signal to the detector. A beam shaping element such as an Axicon lens, LCWG, Risley Prism, Unstable Optical Resonator or MEMS MMA may be used to form or trace the ring-shaped active signal onto the annular region of the ASE. A focusing optic may be used to reduce the divergence of the active signal so that it is collimated or slightly converging when transmitted such that the returned active signal approximates a spot. A filter wheel may be positioned behind the ASE to present separate passive and active images to the detector. These optical sensors may, for example, be used with guided munitions or autonomous vehicles.

An automobile headlamp comprising a light source; a photochromic lens; and a one-way mirror positioned between the light source and the photochromic lens such that when viewing the light source through the photochromic lens, the one-way mirror conceals at least a portion of the light source.
