An endoscope device is provided, including: a first light source section, a second light source section, an imaging section, and a light cut filter. The first light source section is configured to project illumination light to an object. The second light source section is configured to project treatment light to the object. The imaging section is configured to capture an image of the object using reflected light from the object. The light cut filter is arranged between the object and the imaging section and has a transmittance greater than zero and less than a transmittance upper threshold for the treatment light, where the transmittance upper threshold is predetermined based on a rule of avoiding image overexposure.

Endoscope device

An embodiment of a sheath flow device may include: a reflecting plane, aspheric reflecting surface, and a conduit for passage of cells disposed in a central hollow. A focal point of the aspheric reflecting surface is positioned in a location where cells settle. A collimated beam generated by an external light source incident on a first reflective side of the reflecting plane, is reflected to reach a first reflective surface of the aspheric reflecting surface, and reflected before being focused on the focal point, after which the light proceeds to reach a second reflective surface of the aspheric reflecting surface to be reflected to reach a second reflective side of the reflecting plane to emerge after being reflected thereby. The first and second reflective sides and the first and second reflective surfaces may be centrosymmetric. The sheath flow device improves the alignment accuracy of beam commissioning during the application process.
