INO will launch its new auto-centering technology for precision lens alignment at SPIE Optics + Photonics in San Diego on 9 August, 2015. Available for technology transfer, it offers fast and precise alignment and potential cost savings for manufacturers.
How the technology works
The auto-centering method is based on the use of the geometrical relationship between lens diameter, lens radius of curvature, and the thread angle of the retaining ring. The barrel thread angle and the spatial profile of the peripheral region of the lens surface are selected to create auto-centering conditions whereby any decentering of the retaining ring and corresponding tilt of the retaining ring have counterbalancing effects on the centering of the optical element.
Main benefits
In terms of efficiency, the technology will allow manufacturers to achieve an alignment speed of 25 seconds per optical element, precise to within less than 5 µm, without compromising repeatability. INO's auto-centering technology is 10 to 20 times more precise than the conventional drop-in technique, and is faster than machine-assisted methods while providing comparable alignment precision. Easy to implement, this method works with most optical element geometries.
INO will provide more details about its auto-centering technology at the SPIE Optics + Photonics paper session onAugust 9, and will be in booth 338 starting 11 August.
