The present invention provides a transmitted light detection type measurement apparatus for skin fluorescence, which is configured to perform light irradiation and light detection on a reference sample and a measurement target. The apparatus includes a first light source, a second light source, a first optical detector and a second optical detector, a light source switching controller, and an operator.

Transmitted light detection type measurement apparatus for skin autofluorescence

The present invention relates to a filter switching device for a fluorescence endoscopic television camera system, and more particularly, to a filter switching device for a fluorescence endoscopic television camera system, which selectively transmits light to a detector sensor of a television camera according to the white light condition or the fluorescence condition to diagnose patients using a fluorescence endoscope. The present invention provides a filter switching device for a fluorescence endoscopic television camera system, which is configured to conveniently switch filters according to the rotational movement of the camera head, by inducing a change of magnetic forces according to the rotation of the camera head by magnetic substances disposed therein while maintaining a sealed structure inside the camera head connecting between a fluorescence endoscope and a television camera and thus allowing the frame of the camera head mounted with two types of filter to move upward and downward.

The present invention provides a composite light source apparatus for phototherapy of skin disease, in which a light beam having the wavelength and optical power suitable for light-beam treatment is provided to a region to be treated (also called a 'to-be-treated region') through a light guide by using a composite light source so as to improve efficiency of phototherapy of skin diseases of the body including acne, malignant tumors and the like. According to the composite light source apparatus, uniform optical power can be provided through a combination of a plurality of light sources, the optical power can be provided through selection of light of a wavelength range that a user wants, and light from the light sources can be utilized to the maximum with increased light intensity.

Composite light source apparatus for phototherapy

A system is provided for photodynamic diagnosis and therapy of skin diseases. In particular, a camera head is provided to irradiate a white light, a fluorescent excitation light and a therapeutic light for the photodynamic therapy from the inside of a case onto the skin region being in contact with a view hole. Additionally, a digital color TV camera collects the light from the skin region and outputs a generated image signal. In particular, an image processing and analysis system receives the image signals from the camera head to process, analyze and store the same, displays a color image by the white light, a fluorescent image by the excitation light and the therapeutic light for the photodynamic therapy, obtained by the digital color TV camera, and a synthesized image thereof, and controls the general operations of the camera and the light source system.

Apparatus and method for photodynamic diagnosis and therapy of skin diseases and light source system thereof

Disclosed herein is an apparatus for and method of measuring bio-chips, which can implement an illumination method of a novel type that illuminates a bio sample (which may be also referred to as a 'bio specimen') through a side face of a substrate using a diffusion plate to form an evanescent field by the illumination light over the entire surface of a substrate so as to uniformly secure brightness of the illuminated light over a wide area of a substrate, thereby more efficiently measuring fluorescence information of a bio-chip over a wide field of view.

Apparatus for and method of measuring bio-chips using uniform total internal reflection illumination

Disclosed herein is a light source device for fluorescence diagnosis and photodynamic therapy comprising: a plurality of light source means having a wavelength range different from each other and providing selected light; a light path coupling means coupling light emitted from the light source means to the incident direction of a light guide; a filtering means selectively transmitting the emitted light based on the wavelength; and a switching device that is directed to an opening/closing means, established at a long distance to be controlled by a remote control device and selecting the kinds of light sources of the light source means to change the modes of the light. Accordingly, the device simplifies the configuration by excluding elements causing errors in the process of fluorescence diagnosis in the diagnostic region. Moreover, the light source device for fluorescence diagnosis and photodynamic therapy couples the light emitted from a combined light source to provide a sufficient light strength in the visible light region, thus improving the illumination quality to increase the accuracy of the diagnosis and further improving the therapeutic efficiency.

Light source for fluorescence diagnosis and photodynamic therapy

The present invention provides an apparatus for white light observation and fluorescence diagnosis of skin diseases. More particularly, the present invention provides an apparatus for photodynamic diagnosis in which a plurality of excitation light emitting diodes (LEDs) is provided in an image pick-up head, the excitation LEDs being arranged to illuminate the entire examination region in the form of a mosaic by setting respective illumination light axes of the excitation LEDs to illuminate preassigned individual areas of the examination region, thus uniformly illuminating the examination region in a wide field of view with excitation light. In the apparatus for photodynamic diagnosis, the respective excitation LEDs are provided at the same or different angles based on the light axis of the object lens, and thereby it is possible that the beams of the light sources composed of the LEDs illuminate the field of view of the examination region uniformly, thus improving the uniformity of illumination. Moreover, the present invention provides an apparatus for photodynamic diagnosis in which warm white LEDs and cold white LEDs as white light sources are appropriately arranged so as to deliver natural colors and thereby to reproduce natural color images.
