Total-internal-reflection sample lighting installation

Japanese Patent JP6062980

B2

A total internal reflection sample illuminating device, which is capable of generating an evanescent wave easily only through inputting laser light without skill in the art, and which is easy to handle in performing fluorescence observation, non-invasive Raman imaging, or the like, includes: a device substrate (4), which is formed of a material having a refractive index at the same level as that of a slide glass (2) having a sample placed thereon, and which has a top surface on which the slide glass is placed; a light source holder (6) configured to allow laser light emitted by a laser light source (3) to enter the top surface of the device substrate (4) at a predetermined angle; an incident reflecting surface (7) configured to reflect the laser light that has entered the device substrate (4) such that the laser light enters the slide glass (2) and undergoes multiple total internal reflections in the slide glass (2); and an exit reflecting surface (8) configured to reflect the laser light that has entered the device substrate (4) from the slide glass (2) in a direction parallel to the top surface of the device substrate (4).
