The surface flatness of plano elements such as mirrors, prisms and windows can be verified by the use of an interferometer in conjunction with a transmission flat.
Transmission flats are used when measuring the surface flatness or transmitted wavefront of flat surfaces or optics. The Tower 4” TX Flat provides a clear aperture of 100mm, while the Tower 6” TX Flat provides a clear aperture of 153mm. The TX Flat is an assembly of a precision optical window mounted in an anodized aluminum ring that provides mounting compatibility with most bayonet style housings. The transmission flat assembly is supplied in an aluminum shipping/storage case.
