I am looking for an optical piece that can act as a mirror when the angle of incidence is close to normal (90 degrees) but acts as a see-through glass when the angle of incidence is less than 60 degrees?
Alternatively it can be a filter placed in front of a mirror that passes a lot of light at an angle of incidence close to normal but blocks light at an angle of incidence less than 60 degrees.
Is there such a thing?
