Abstract
An interferometric measuring device includes a reference arm having a reference surface and a measuring arm having lighting optics for deflecting measuring light onto a measuring surface of an object to be measured, and having an image recorder connected to an analyzing device. A rapid, simple measurement with a rugged design of the measuring device may be achieved by configuring the lighting optics as a light guide body insertable into a cavity in the object to be measured, having a peripheral, radially symmetrical effective reflex surface directed radially or obliquely outward, and also including at least one deflector surface deflecting the measuring light onto same.
