![]() Lasers, Optics, Electronics. Made in Germany. Bertha-von-Suttner-Str. 5 37085 Göttingen Germany | ![]() ALPHALAS offers etalons made of fused silica for wavelength tuning and single-frequency operation of lasers. Etalons with diameter 8 mm and thicknesses 0.2 mm, 0.9 mm or 1.3 mm, coated with different reflectivities in the near infrared region, are available from stock. Upgraded to resonant reflectors (stack of very high precision fused quartz flats with spacers and different number of elements), these have very high periodic spectral selectivity and very high damage threshold. Customer-specific designs are also available. |
![]() 80 Colonnade Rd. North, Unit 1 Nepean, Ontario K2E 7L2 Canada ISO 9001:2015 | ![]() 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. |
