ÄPRE Instruments designs and manufactures high-performance Fizeau interferometers for precision surface and wavefront metrology. Built around a camera-limited optical architecture and proprietary REVEAL metrology software, ÄPRE systems deliver fast, accurate, traceable measurements for both production and R&D environments.

The ÄPRE range spans three interferometer families — the S-Series for high-performance general-purpose Fizeau measurement, the Ä-Series for applications demanding extreme slope acceptance and spatial artifact reduction, and the Ä9|9MP for dedicated mid-spatial frequency (MSF) surface characterisation. All systems ship with REVEAL software included, with free lifetime upgrades.

Optional add-ons include SpectrÄ SCI (Spectrally Controlled Interferometry) for measurement of glass substrates, prisms, and domes without surface preparation, and the ÄTLas 633 tunable laser source for large-aperture and long-cavity applications. Photonic Solutions is the authorised UK and Ireland distributor for ÄPRE Instruments. Contact our team to discuss your application or arrange a demonstration.
