Prism
The core uses of a prism include turning light at a specific angle, while also achieving light deviation and image orientation adjustment. The way it interacts with light is entirely determined by its own design. When light is incident on a prism, there are mainly two action paths: one is that the light first reflects on a single or multiple surfaces of the prism and then exits; the other is that the light is directly refracted while passing through the prism substrate. From examples, the action of a right-angle prism belongs to the former. When light is incident, it first reflects on one of its surfaces, ultimately achieving a 90° turn of the light. A wedge prism belongs to the latter; because the thickness of its substrate varies, the light deviates due to refraction when passing through. Prisms include the following types: dispersive prisms, reflective prisms, roof prisms, etc.
