Compact Focus Module

New Scale Technologies Inc. has upgraded the lifetime specification of its miniature M3-F focus module and provided new repeatability data for it. The module replaces fixed lens holders in compact board cameras for biometric detection and medical diagnostics applications. The new lifetime is >2 million cycles mean time between failure in a fixed orientation or >500,000 cycles in random orientation. Position repeatability is ±5 µm unidirectional and ±20 µm bidirectional, demonstrating high performance for high-resolution imaging applications. Image quality is directly proportional to lens position repeatability with autofocus algorithms. With a 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.
