Fiber Optic Collimator for ST Cables
Here you can see the holes are a small fraction of a milimeter. Theoretically, you should be able to focus the laser beam to a spot the same size as the fiber core diameter. With a 100um fiber, that gives a resolution of 0.1mm or about 0.004 inch.
* Size: 1" x 1" x 3/8" (25.4mm x 25.4m x 9.5mm
* Mounting Holes: 6-32, 2 sides
* Laser Wavelength: 600-850nm
This device allows you to change the highly divergent and thus not very dangerous output from a fiber coupled laser into a narrow beam or a finely focussed spot which can be extremely dangerous, especially when used with invisible infrared lasers. Be sure to use appropriate safety goggles and avoid stray reflections when working with this.
