Ordering data for polygon scanners

Lincoln Laser makes rotating polygon scanning mirrors and assemblies. That's their main business. We plan to put together a laser rangefinder using Acuity Research electronics and a Lincoln Laser scanner.

Here are their options.

Polygon scan mirror worksheet - mirror dimensions


Sample mirror specifications for our mirror

These are not the numbers we want to use,
but are illustrative values generated by the Lincoln sales rep.

Section 1 - Mechanical specifications

Illustrative dimensions only.

We need an 6-face prism, with maybe 4 square inches of face area. Bob Clark is working on determining the needed face area. 6 faces at 4 square inches each is no problem mechanically, although the device is rather bulky.

Section 2 - Optical specifications

Bob Clark, please confirm these are OK.

Section 3 - Physical specifications

Vertical, mirror up - probably.

Section 4 - Estimated information

We're well within the strength limits for the material. This is an aluminum mirror.




Lincoln Laser's biggest stock scanner assembly

Can we use this, or will we need a bigger, custom job?
