The picoFlex from Point Source Ltd. is a miniature collimator for fiber-coupled laser diodes. It measures 6 x 22 mm, and its output beam diameter is between 0.5 and 2.0 mm. The picoFlex is optically centered to ±1 mrad with a beam-pointing error of less than 1 µrad. It has a standard polarization-maintaining fiber that is available in 1- to 10-m lengths. Designed primarily for use at specific wavelengths from 635 to 830 nm, the collimator also can be used with argon-ion lasers from 458 to 514 nm and diode-pumped solid-state lasers at 532 nm.
