A prism array light redistribution apparatus for an eye imaging system including light transmitting fibers, light receiving fibers, and a micro prism array optically coupled to bridge the light transmitting fibers and the light receiving fibers, configured to receive light having a bell-shaped angular distribution from the light transmitting fibers and refract light emitted by the light transmitting fibers to enter the light receiving fibers

A laser-based fiber-coupled wide-spectrum light system is provided. The system includes a laser device and one or more phosphor members configured and arranged to provide wide-spectrum emissions. One or more fibers are configured and arranged to receive the wide-spectrum emissions.

A fluorescent optical system and a fluorescent image inspection system are provided. The fluorescent optical system includes a platform, at least one light source device, and at least one first filter. The platform is configured for placement of a sample to be inspected. The at least one light source device is configured to illuminate the sample to be inspected, so that the sample to be inspected is stimulated to generate a fluorescent light. The at least one first filter is correspondingly arranged in an optical path of the at least one light source device, so that an excitation light passes through the at least one first filter. An incident angle is formed between the excitation light and the platform, and the incident angle is less than 90 degrees.

A light source unit includes: a first light emission point from which a first beam is emitted; a second light emission point from which a second beam is emitted and which is disposed apart from the first light emission point in a second direction perpendicular to a first direction; a deflection element that deflects the first and/or second beam; and a first condensing optical element that focuses, on a light collection surface, the first and second beams. The first beam at the first light emission point overlaps the second beam at the second light emission point in a third direction, and on the light collection surface, the first and second beams overlap each other in the second direction and are separate from each other in the third direction.

A construction component forms at least a part of a structure that faces a target space. The construction component has a first function, a second function, and a third function. The first function is a function of emitting illumination light toward the target space. The second function is a function of allowing incident light to enter the construction component. The incident light is emitted from a light source disposed out of a projection area, viewed from the target space, of the construction component and is incident on the construction component via a light transmission member. The third function is a function of converting the incident light into the illumination light.

A light-emitting system includes an optical fiber, a first light source unit, a second light source unit, and a light-guiding member. The optical fiber includes a wavelength-converting portion containing a wavelength-converting element. The wavelength-converting element may be excited by excitation light to produce a spontaneous emission of light having a longer wavelength than the excitation light and may also be excited by an amplified spontaneous emission of light. The first light source unit makes the excitation light incident on the optical fiber. The second light source unit makes seed light, causing the wavelength-converting element that has been excited by either the excitation light or the amplified spontaneous emission of light to produce a stimulated emission of light, incident on the optical fiber. The light-guiding member guides the light coming from the optical fiber and lets the light emerge therefrom.

In a lighting system an optical fiber includes a light incident portion, a light emerging portion, and a wavelength-converting portion. The wavelength-converting portion is provided between the light incident portion and the light emerging portion. The wavelength-converting portion contains a wavelength-converting element which is excited by excitation light and amplifies a spontaneous emission of light, having a longer wavelength than the excitation light, with an amplified spontaneous emission of light. A first light source unit makes the excitation light incident on the light incident portion. A second light source unit makes seed light, which causes the wavelength-converting element excited by the excitation light and the amplified spontaneous emission of light to produce a stimulated emission of light, incident on the light incident portion. A lighting unit, into an external space, light emerging from the light emerging portion of the optical fiber.

A photoconversion device includes a holder, a wavelength converter, and an optical element. The holder holds an output portion that outputs excitation light. The wavelength converter includes an incident surface section including a protruding surface to receive the excitation light from the output portion and emits fluorescence in response to the excitation light incident on the incident surface section. The optical element includes a focal point surrounded by the incident surface to direct the fluorescence emitted by the wavelength converter in a predetermined direction.

A high power uniform light beam is generated on an oblique plane by one or more diode lasers and 2 or more light pipes. The light pipes may be trapezoidal so that the illuminated area is substantially square. The light pipes may be elliptical so that the illuminated area is substantially circular.

A laser beam delivery apparatus for a microscope comprises first and second optical diffusers that are configured to move in a periodic manner with a respective different frequency. Each optical diffuser may comprise a spinning disk. The laser light is spatially randomized by the first spinning diffuser and its spatial pattern is further randomized by the second diffuser. The second diffuser prevents any spatial pattern from repeating after one revolution of the first diffuser, which prevents beating patterns from forming when the light is imaged through a spinning confocal disk and increases the uniformity in other cases.
