LASER FOCUSING

Photonics Spectra
Dec 2001
Prior Scientific Inc.Request Info
 
A laser autofocusing system with microprocessor control and precision optics that adjust to different microscopes and optical systems has been released by Prior Scientific Inc. Suitable for reflective specimens, the compact LF100 has digital control that automatically senses when a sample has moved out of the field of view and stops the focus drive; LEDs indicate the focus status. Adjustment of the focus trim and loop gain is performed in the processor, but manual focus is possible using a digipot. The module comes with limit switch inputs, a microstepping drive for the focus motor and an RS-232 port for programming gain, servo loops, speed limits and other parameters.
