 Arzbergerstr. 10 82211 Herrsching Germany |  Hamamatsu Photonics offer ultra-compact sensors that house an InGaAs PIN photodiode and a Fabry–Pérot Interferometer (MEMS-FPI) tunable filter that can vary its transmission wavelength depending on the applied voltage. Product-specific web page |
 Lasers, Optics, Electronics. Made in Germany. ALPHALAS GmbHBertha-von-Suttner-Str. 5 37085 Göttingen Germany |  The Fabry–Pérot interferometers offered by ALPHALAS are high-resolution spectroscopic instruments having applications in spectral analysis of narrowband light sources like gas discharge lamps and lasers. These are especially useful for analyzing the spectral content of pulsed lasers, because they allow for single-shot measurements. The interferometers consist of two high-precision mirrors with a flatness better than λ/40 over 90% of the aperture, having broadband coatings and spacers of different thickness. The working aperture is either 22 mm or 48 mm, and the reflectivity finesse is > 120. The standard spectral range is 450 nm … 1100 nm, others on request. Combined with our CCD linear array, the interferometers form a versatile spectral analysis system. Product-specific web page |
 all wavelengths. TOPTICA Photonics AGLochhamer Schlag 19 82166 Gräfelfing Germany |  The FPI 100 is a confocal, scanning Fabry–Pérot interferometer with a built-in photodetector unit, designed for measuring and controlling the mode profiles of continuous wave (cw) lasers. The FPI is available with different mirror sets and photodetectors for wavelength ranges between 330 nm and 3000 nm. Product-specific web page |
 80 Colonnade Rd. North, Unit 1 Nepean, Ontario K2E 7L2 Canada |  LightMachinery manufactures the world's finest solid and air spaced etalons. Our fluid jet polishing systems allow us to routinely create surfaces that are better than λ/100 peak to valley. Solid etalons, air spaced etalons, piezo tunable etalons, Gires–Tournois etalons – LightMachinery has extensive expertise in the manufacturing and testing of all kinds of Fabry–Pérot etalons from 1 mm square to 100 mm in diameter. These devices require high quality, very flat optical surfaces and extreme parallelism to achieve high performance, making them a good match for the polishing and metrology at LightMachinery.
