Interferometry, Fabry-Perot industrial filters Typical Applications in ActiveOptics
Faserpositionierung Motion controllers Dynamic error correction (e.g. in polygon scanning mirrors) Patented feedforward tech- niques for rapid settling
Motorsteuerungen Ceramic Linear motors & Stages These systems can perform opti- cal beam steering over ranges of up to 100 mrad, have extremely low response times (millisecondsto microseconds) and resolutionsin the nanoradian range. They are ideal for dynamic operation (e.g. tracking, scanning, drift and vibra- tion cancellation) as well as static positioning of optics and samples. Optical path length stabiliza-tion Dynamic Digital Linearization (DDL) to eliminate tracking error
Index Vibration cancellation (lasersystems, imaging) Finite Element Analysis (FEA) computer-designed flexures for ultra-precise trajectory control Image stabilization (astronomi-cal telescopes, imaging) Image resolution enhancement(pixel multiplication, dithering) Invar, titanium, steel and alu- minum versions for optimized thermal match Laser beam stabilization (res-onators, optical setups) Standard platforms accommo- date optics to 100 mm in diameter Laser beam scanning (lithogra-phy, optical setups) Laser beam steering and tracking (telecommunicationsatellites, etc.) Custom designs for optics up to 300 mm diameter (astro- nomical telescopes) Mass storage device testing and manufacture (CD, DVDmastering) Bore-sight systems Beam steering, alignment,switching
