2. Beam splitter - Wikipedia

   en.wikipedia.org/wiki/Beam_splitter

   A very thin half-silvered mirror used in photography is often called a pellicle mirror. To reduce loss of light due to absorption by the reflective coating, so-called "Swiss-cheese" beam-splitter mirrors have been used. Originally, these were sheets of highly polished metal perforated with holes to obtain the desired ratio of reflection to ...

6. Elitzur–Vaidman bomb tester - Wikipedia

   en.wikipedia.org/wiki/Elitzur–Vaidman_bomb_tester

   Figure 3: Once the photon encounters the beam splitter it enters a superposition wherein it both passes through and reflects off the half-silvered mirror. A superposition in the bomb tester is created with an angled half-silvered mirror, which allows a photon to either pass through it, or be reflected off it at a 90-degree angle (see figure 3 ...

7. Reticle - Wikipedia

   en.wikipedia.org/wiki/Reticle

   Diagram of three types of reflector sights that produce collimated reticles. The top uses a collimating lens (CL) and a beam splitter (B) to create a virtual image at infinity (V) of a reticle (R). The bottom two use half silvered curved mirrors (CM) as the collimating optics with the reticle off-set or between the mirror and the observer.
