系軸測定装置。An optical system to be measured that combines a light source and a lens system, and an optical system that receives light emitted from the optical system to be measured, converts the image of that light into an electrical signal, and then converts the image of the light that is converted into an electrical signal. A television camera that obtains a video signal for the light image based on the output from a comparator that compares the luminance signal with two different thresholds, and displays the video signal from the television camera in the form of an image. a display, a position detection unit that detects the position of different brightness based on the video signal from the television camera, and a position detection unit that detects the position of the light source in the optical system to be measured relative to the optical axis of the lens system based on the position detection signal detected by the position detection unit. What is claimed is: 1. An optical system axis measuring device comprising: a calculation section that calculates a tilt angle; and a display that displays the tilt angle.
