Laser Scanning Mirrors

High acquisition speed is required to track fast processes especially in living samples.

Laser scanning mirrors.

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. 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. 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. Including the group of galvano scanner mirrors where the optical coating a deflection range from 22 58 is taken into account and whose outer dimensions are adapted to the high scanning frequency.

Next scan technology 4 851 views. Ulo optics offers the lsm series of monocrystalline silicon mirrors for use in galvo based scan heads. Laser patterning and on the fly drilling with polygon scanner systems next scan technology duration. A central axis through which an axle fits and some number of mirror planes arranged in a circle around it.

With an off axis pm and the incident parallel laser beam orthogonal to the optical axis of the. Protected aluminum gold silver and dielectric coatings for wavelengths ranging from 250 nm to 10 6 μm. The steering of the beam can be one dimensional as inside a laser printer or two dimensional as in a laser show system. Most laser scanners use moveable mirrors to steer the laser beam.

Typically coatings come with a secondary reflectivity band for guiding laser beam typically hene 633 nm. It has the additional benefit of providing a better fluorescence signal and reduced photobleaching. The mirrors are designed for the use with high power lasers and are sized to accomodate up to 30 degrees of deflection. 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.

Many different mirror coating configurations can be applied on scanning mirror substrates. A scanning mirror is kind of like one slice of a disco ball. 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. 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.

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