Lightweight mirrors
Aluminium has a low density (2.7g/cm3), and can withstand many
kilowatts of laser power. Gold coated Aluminium is widely used for scanner
mirrors, high speed shutter mirrors, high speed flying optics mirrors, and any
application where lightweight and high power handling is needed. Aluminium is
easily machined allowing mounting features to be made as part of the mirror.

Cylindrical mirrors
Are used for generating a line focus. An intense line
of energy can then be scanned over surfaces for heat treatment, or for other
applications. Weak cylindrical mirrors can also be used to correct the
inherently astigmatic beams from slab laser discharges.
Shutter mirrors
When not in use the laser beam is directed to a beam dump or some
other collector. Shutter mirrors need to be lightweight to allow rapid movement
in and out of the beam, and are often curved to disperse the beam into the
dump. Convex axicons, convex cylindrical, and faceted mirrors are offered from
copper and aluminium.
Cassegrain Mirrors
Mirrors with through holes are a speciality of Laser Beam
Products. Our polishing technology allows surface form to be maintained right
up to the circumference of through hole. Through holes can be central, angled
through the mirror, or offset. Just about any shape that can be machined can be
made into a mirror. Uniquely our gold coating covers the mirror face, edges and
internal surfaces of the mirror.
Knife edge mirrors
Used as a variable beam splitter, a knife edge can be passed into
a beam to split the beam spatially. Useful for beam profiling and analysis.
Gold coated copper knife edges will work with many kilowatts of power, and are
of course polarisation insensitive.
Roof prisms
Are used to split a beam into two parts. This type of beam
splitter is cheap, adjustable, polarisation insensitive, and will work with
high powers. |
