New Scale Technologies (Victor, NY) has upgraded the lifetime specification and provided new repeatability data for its miniature M3-F focus module, which replaces fixed lens holders in compact board cameras for biometric detection, medical diagnostics, machine vision and other applications. Based on continuous design improvements and testing, the new lifetime specification is >2 million cycles mean time before failure in a fixed orientation or >500,000 cycles in random orientation. The position repeatability is ± 5 microns uni-directional and ± 20 microns bi-directional, demonstrating best- in-class performance for high-resolution imaging applications. With a total footprint of 20 x 22 x 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.
