Focus Module

Photonics Spectra

New Scale Technologies Inc.Request Info
 
New Scale Technologies Inc. has provided new repeatability data for its miniature M3-F focus module and upgraded its lifetime specification. The new device replaces fixed lens holders in compact board cameras for biometric detection, medical diagnostics and machine vision applications. The lifetime specification is now >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 replaces fixed lens holders over CCD or CMOS image sensors without adding to the camera size.
