Nanomotion (Stand S3-300), a subsidiary of Johnson Electric and a designer and manufacturer of advanced motion systems, is showing two new products at DSEI: the OIS (Optical Image Stabilisation) Stage motion module and the LF14 Linear Filter Changer, writes Robin Hughes.
The OIS Stage is designed to steer and stabilise an image, based on input from a dual-axis accelerometer. The module delivers 2mm travel and can stabilise vibrations of 3Hz over 1mm and 15Hz over 0.2mm. It operates with 1μm position resolution and has been tested to 1,500g shocks, for use with hand-held weapons − and can move a lens up to 10mm in diameter.
Based on the S787 linear shutter, which uses a solid blade, the LF14 carries two filters, designed for hand-held and flight devices.
It provides 14mm travel in 70 milliseconds and can be integrated directly over a laser source. The LF14 has been tested to 350g max shock and 10g rms vibration, operating closed loop, and can hold position without power. It is rated for -40°C to +70°C and can be used as a filter changer or a NUC shutter (when used with a solid blade).
