The present invention relates to a device for an application of directed actinic radiation to a subject, said device comprising: an exposition tunnel being capable of surrounding said subject to be exposed to said actinic radiation and being formed of one semi-cylinder barrel-shape first surface made of a material substantially permeable to said actinic radiation, and of at least one second surface made of said material substantially permeable to said actinic radiation and capable of complementing the first surface in forming said exposition tunnel; the surfaces of said exposition tunnel separating an inner space where said subject is exposed to said actinic radiation, from outer spaces where a plurality of radiation sources capable of emitting actinic radiation through said surfaces are mounted; said first and second parts of the chassis of the device being configured to complement each other in forming the outer shape of the device; said device further comprising at least one further outer space separated from said inner space and located at either one or both of the longitudinal ends of the exposition tunnel, said at least one further outer space housing a plurality of additional radiation sources configured to emit radiation, wherein at least one of the radiation sources and the additional radiation sources comprise at least one reflector or a plurality of reflectors. An improved device distinguishes in that at least one of the radiation sources and the additional radiation sources comprise LEDs or a plurality of LEDs, and that the at least one reflector or the plurality of reflectors collimate the radiation emitted by said at least one of the radiation sources and the additional radiation sources.

A light based system for treating an eye includes a mask that is configured for positioning on the eye and a light source that is configured to deliver therapeutic light. The mask has an inner surface that is positionable against the eye and an outer surface that is opposite the inner surface. The mask is optically opaque to prevent transmission of light through the mask and the mask includes at least one transparent opening that allows transmission of light through the mask to target tissue of the eye posterior the transparent opening. The light source is positioned relative to the mask so that the delivered therapeutic light irradiates at least a portion of the mask and the transparent opening. Therapeutic light traverses through the transparent opening to the target tissue positioned posterior the transparent opening.

A photo-treatment device includes a non-opaque treatment substrate and a radiation-collector beside the substrate. The substrate is sized for a person at which radiation is to be emitted from above the substrate. The substrate has a front surface for receiving the person thereon and a back surface. The radiation-collector captures excess radiation peripheral to the substrate and redirects the excess radiation to the back surface of the substrate.

A micro-electrode array (1) comprising a flexible substrate (2) and a multiplicity of electrodes (3) for electrically measuring neural activity is described. The electrodes (3) are arranged on the substrate (2), project from the plane of the substrate (2) and have a core (4). A plurality of measurement lines (9) that are electrically insulated from one another are arranged around the core (4). Adjacent to the end surface (7) of the core (4), at the end of the electrodes (3) there are a plurality of electrode surfaces (8) arranged in a manner distributed spatially around the end surface (7), said electrode surfaces in each case being electrically conductively connected to an associated measurement line (9). The micro-electrode array (1) is passivated with a polymer-containing material, such as e.g. polyimide, such that only the electrodes (3) electrically contact neural tissue with their electrode surfaces (8, E1, E2).

The pre-determined time function comprises a plurality of packets, each packet of the plurality of packets being followed by a packet interval, and each packet including a pulse alternation between a pulse of the first light and a pulse of the second light.

A laser device for cancer treatment is provided comprising a handheld cylinder for partial insertion into a body cavity and a plurality of cone mirror reflectors in the cylinder, each reflector with a hollow central profile. The system further comprises a plurality of ring lenses in the cylinder and a subminiature (SMA) connector inside a first end of the cylinder that receives laser light from a fiber cable, the laser light then passing through the reflectors and the lenses and exiting the cylinder via a housing tip at a second end of the cylinder in a 360-degree arc. The cone mirror reflectors are alternatively solid with truncated apexes. The cylinder is made of one of borosilicate glass and polyamide resin.

A laser device for skin treatment includes: a laser generating unit including a diode laser for generating a pulse capable of being varied to a pulse width of 100 picoseconds (ps) to 2000 ps by a dedicated driver having a rising time of 100 ps or less and a pulse width adjustment unit for adjusting a width of the pulse generated by the diode laser, the laser generating unit configured to generate a single or a plurality of pulses; and a laser amplifying unit including a pumping lamp and a single or a plurality of amplification mediums having a rod structure for absorbing light energy from the pumping lamp, wherein, in the laser amplifying unit, a pulse supplied from the laser generating unit passes through at least one of the single or a plurality of amplification mediums a plurality of times inward from the outside and is gradually amplified.

An apparatus for inhibiting melatonin synthesis in a horse comprises a blinker having an internal surface of which at least a part is diffusing. A source of light is positioned for direction into the horse's eye by the diffusing-surface. The light source and diffusing surface are configured such that the light directed into the horse's eye is blue.
