Laser Scanning Mirrors

A 2d mirror with both electrostatic and electromagnetic actuation methods a mems micro electro mechanical system mirror is a tiny solid state mirror mirror on a chip actuated by micro size motors in one or two dimensions.

Laser scanning mirrors.

Most laser scanners use moveable mirrors to steer the laser beam. Ulo optics offers the lsm series of monocrystalline silicon mirrors for use in galvo based scan heads. The study analyzes polygonal mirror pm scanning heads for one of their most utilized setups. A laser beam pointed at the mirror is precisely deflected and steered by the scanning mirror to reach a target.

With an off axis pm and the incident parallel laser beam orthogonal to the optical axis of the. Optics balzers offers a wide range of customized laser scanning mirrors. Typically coatings come with a secondary reflectivity band for guiding laser beam typically hene 633 nm. High acquisition speed is required to track fast processes especially in living samples.

The mirrors are designed for the use with high power lasers and are sized to accomodate up to 30 degrees of deflection. It has the additional benefit of providing a better fluorescence signal and reduced photobleaching. Many different mirror coating configurations can be applied on scanning mirror substrates. This biaxial mems micro electronic mechanical systems mirror operates at 28khz and 60hz with a 40 view angle making it a perfect engine for applications such as laser.

A central axis through which an axle fits and some number of mirror planes arranged in a circle around it. With its cutting edge technology ultimems has demoed a 720hd raster scanning laser projector with the world s first pure electrostatic biaxial raster scanning mirror. If a laser is aimed at such a thing while it s spinning the laser beam is deflected into a long line or plane outward from the axle. The steering of the beam can be one dimensional as inside a laser printer or two dimensional as in a laser show system.

Additionally the mirrors can lead to a periodic motion like the rotating mirror polygons in a barcode scanner or so called resonant galvanometer scanners or to a freely addressable motion as in servo. Next scan technology 4 851 views. A scanning mirror is kind of like one slice of a disco ball. A resonant scanner is a type of galvanometric mirror scanner that allows fast image acquisition with single point scanning microscopes true confocal and multiphoton laser scanning.

The thickness is optimized to provide low mass while minimizing distortion at high scanning speeds.
