Optical mirror adjustment means are disclosed for use in a projection television system having a rear projection viewing screen. The means according to the invention provide for adjusting the reflecting angles of a mirror reflecting an aerial image of a projected television image onto the screen. Pivot means provide for tilting the mirror in elevation, and screw means provide for positionally adjusting and fixing the mirror in a desired elevation angle. Screw means attached to the pivot means provide for positioning and fixing the mirror as azimuthally. The optical mirror adjustment means are such that the mirror can be adjusted to reflect the aerial image in precise coincidence onto the viewing screen.
