Spectrally Controlled Interferometry from Äpre
Fizeau Interferometry without Back Reflections!
Do confused interference fringes frustrate your ability to make plates and prisms? Finally there is a better way, without the hassle of painting, greasing or taping the back surface. a better way, without the hassle of painting, greasing or taping the back surface.
Äpre’s Spectrally Controlled Interferometry (SCI)-based interferometers align with laser ease and isolate like a broadband light source, electronically switching between the two modes at camera frame rates. SCI enables you to selectively see the surface of interest.
Their customer Sydor Optics says: “SCI enables the accurate measurement of flat and ultra-parallel surfaces without the interference of background fringes that are common for standard interferometric systems.”
Äpre’s SCI was awarded one of Laser Focus World’s highest awards for innovation in photonics, a Gold-Level Honoree. We are proud to be recognized by this leading industry journal for the innovation that SCI brings to optical testing.
