Beschreibung
Zusammenfassung:	A beam splitting and combining device includes a first prism, a second prism and a first optical film. The first prism includes a first surface, a second surface and a third surface. The second prism includes a fourth surface, a fifth surface and a sixth surface. The fifth surface and the second surface are attached to each other. The first optical film is formed between the second surface and the fifth surface by coating. A beam in a first range of wavelengths is configured to pass through the first surface, the second surface, the first optical film, the fifth surface and the sixth surface in order or in reverse order, or is configured to pass through the first surface and the third surface in order or in reverse order.
