 | M3-F focus module: superior repeatability for high-resolution imaging
|
Based on continuous design improvements and testing, we've released new lifetime and repeatability specifications for our miniature M3-F focus module for compact board cameras. The new specifications are:
- > 2 million cycles lifetime (MTBF) in a fixed orientation
- > 500,000 cycles lifetime (MTBF) in random orientation
- +/- 5 microns uni-directional repeatability
- +/- 20 microns bi-directional repeatability
The lifetime is competitive and the position repeatability far superior to other miniature focus solutions. This is a critical advantage with autofocus algorithms such as
"image resolution hill climbing," where image quality is directly proportional to lens position repeatability.
In addition, 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.
The embedded closed-loop drive delivers high repeatability, low temperature dependence and no hysteresis. With the added benefit of lower external processing requirements and lower overall system cost, the M3-F is the clear winner for compact, high-resolution camera applications.
