An endoscope includes: an aperture portion having an opening to which light from an observation target site is incident; a filter unit that has a plurality of filters and selectively transmits light based on any one of the filters; a color separation prism that is formed by a plurality of separation prisms which separate light, which has transmitted through the filter unit, into beams of light having different color components from each other; a plurality of image sensors that are provided so as to respectively correspond to the separation prisms and capture an image based on the beams of light; a signal output unit that outputs image signals captured by the image sensors respectively; and a filter disposing unit that disposes any one of the plurality of filters so that the light is incident to the disposed one of the plurality of filters.

Endoscope and endoscope system

Disclosed is an endoscope including: a four-color separation prism configured to separate light from an object into three primary colors of light and infrared light; four image sensors configured to convert optical images of the separated three primary colors of light and an optical image of the separated infrared light into electrical signals; and an output device configured to output the converted electrical signals.

Endoscope and endoscopic system

A medical camera includes a camera head having a first a first color separation prism, a second color separation prism, a third color separation prism, and a fourth color separation prism. The four color separation prisms respectively separate light incident from an affected area into a blue, red and green color components, and an infrared (IR) component. A light emission surface of the first color separation prism is disposed opposite to a light emission surface of the second color separation prism. A light emission surface of the third color separation prism is disposed across an incident ray which is incident vertically to an object side incident surface of the first color separation prism.

Medical camera

A four color separation prism includes a first color separation prism, a second color separation prism, a third color separation prism, and a fourth color separation prism, which respectively separate light incident from an affected area into a blue, red and green color components, and an infrared (IR) component. The first color separation prism, the second color separation prism, the third color separation prism, and the fourth color separation prism are sequentially disposed from an object side when receiving the light incident from the affected area.

Four color separation prism

A four color separation endoscope prism includes a four color separation prism having a first color separation prism, a second color separation prism, a third color separation prism, and a fourth color separation prism which respectively separate light incident from an affected area into a blue, red and green color components, and an infrared (IR) component. The first color separation prism, the second color separation prism, the third color separation prism, and the fourth color separation prism are sequentially disposed from an object side when receiving the light incident from the affected area.

An endoscope includes a four color separation prism having a first color separation prism, a second color separation prism, a third color separation prism, and a fourth color separation prism which respectively separate light incident from an affected area into a blue, red and green color components, and an IR component, first, second, third and fourth color image sensors, and a signal output. The first color separation prism, the second color separation prism, the third color separation prism, and the fourth color separation prism are sequentially disposed from an object side when receiving the light incident from the affected area. The first color image sensor is disposed opposite to the second color image sensor and the third color image sensor across an incident ray which is incident vertically to an object side incident surface of the first color separation prism.
