Benefits of New Scale's miniature M3-F focus modules are proven in next-generation machine vision, biometric ID and medical systems
Precision piezoelectric lens motion modules are now in production in camera systems from leading OEMs in key markets; more than 50 additional OEMs have completed qualification of camera systems to begin production in 2011- 2012
Victor, NY — Oct. 11, 2011 — New Scale Technologies today announced that its miniature M3-F focus module is currently in production in commercial camera systems for biometric identification, medical devices and various machine vision applications by leading OEMs in these markets. More than 50 OEM additional customers have completed qualification of the M3-F focus module in vision systems that are slated to go into volume production over the next six months.
New Scale and its OEM customers worked closely with precision lens manufacturer Sunex (http://www.optics-online.com) on a large number of these projects for help with lens specification and optical system design.
"The ability to adjust focus using software is increasingly a high-priority feature in compact cameras for applications requiring high image quality along with fast and automatic image capture, such as biometric detection and medical devices," said David Simpson, vice president of marketing and sales for New Scale. "The widespread adoption of the M3-F is validation of its performance advantage and the ease with which it can be integrated into OEM board camera systems."
In biometric identification, the M3-F focus module improves usability by enabling image capture over a greater depth of field, typically about one inch to infinity depending on the lens. This makes it easier to position the eye in front of a biometric ID camera and results in a more accurate iris, face or fingerprint match with less time and effort on the part of the user.
In medical diagnostic systems, the M3-F focus module enables faster and more accurate sample analysis and alleviates the need for highly meticulous sample positioning. It also improves usability of medical devices such as endoscopic imaging by reducing the amount of time required to align the scope.
The M3-F also adds flexibility to machine vision systems, allowing them to image a wider variety parts without regard to their exact distance from the camera, and to image parts that have significant variations in depth.
With a footprint of 20 x 22 mm, a height of 16 mm and no external control board, the M3-F easily replaces fixed lens holders over CCD or CMOS image sensors without adding to the camera size. It is compatible with image sensors up to 17x17 mm, including the 1/2” and 1/1.8” formats.
The M3-F accepts high-quality glass or polymer lenses, which have greater transmission and clarity than non-traditional composite lenses of liquid or liquid crystal. It accepts standard threaded lens assemblies from M8 to M12 in size and up to 5 grams in weight.
The M3-F moves lenses with 0.5 micron position resolution and very low tip/tilt, keeping the image focused on the center of the image sensor. The embedded closed-loop drive delivers high repeatability, low temperature dependence and no hysteresis.
