CO2 Laser Optics: Reflective Mirrors

Laser Beam Products manufactures and stocks a wide range of standard replacement mirrors for laser cutting and laser engraving systems which meet, or exceed, the OEM specification. They also provide laser mirrors and reflective laser components for obsolete or obscure machines, which are often unavailable elsewhere.

Much of their business is working with customers to solve challenging optical problems across many industries as varied as Defense, Chemical, Nuclear, Environmental Monitoring, Aerospace, Printing, and Scientific Research. We welcome enquiries at an early stage, where our twenty years of experience can get a project on the right road at the very start.
Laser Beam Products can fabricate, polish and coat mirrors from customer supplied material, working to customers drawings, or to their own designs using software like Zemax, AutoCAD, BeamCAD. Their manufacturing techniques lend themselves to the efficient production of small numbers of optics, even just one optical component, very cost effectively. Because they manufacture almost entirely “ in house” delivery times are quick as well.
They pride themselves in their flexibility with mirror materials, optical coatings, mechanical and optical tolerances, even adapting existing parts to meet the demands of the customer's applications. Just about everything is standard to them!

Flat Mirrors  |  Curved Mirrors   |  Application Notes

Applications for Laser Beam Products' gold coated mirrors include CO2 laser mirrors, Er;YAG lasers, Near IR, Far IR, Quantum Cascade Lasers (QCL), Phase Retarding CO2 Mirrors and High Power Fiber Lasers

Materials that work as substrates in these applications are:

Standard coatings that Laser Beam products uses are:

Both standard and custom items are available at competitive prices and with short delivery times.

Flat Mirrors

Flat mirrors find wide uses in industrial laser systems, as well as medical, scientific and research applications. 

Copper based mirrors in particular provide a rugged and durable mirror with good reflectivity across a broad spectrum of the infrared. Our electroplated gold coating offers good reflectivity and high damage resistance. They are widely used in CO2 laser beam delivery where their massive power handling ability gives a long working life. Our mirrors are fitted to a 40KW welding laser.

Aluminium mirrors are lightweight, and ideal for scanning applications. 

Silicon mirrors are always used with a coating, such as Max R, phase retarder, and are suitable for many infra red wavelengths. Although lightweight and stable they have lower laser damage resistance compared to all metal mirrors. 

Molybdenum mirrors offer a very hard, scratch resistant, mirror surface. 

Unique manufacturing methods allow cost effective supply of prototypes and small numbers of parts without tooling or set up charges. 

Curved Mirrors

Spherically curved mirrors are commonly used in laser cavities  and in laser beam expanders for high power lasers. 

Cylindrical mirrors are used for correcting astigmatic beams from slab discharge lasers and laser diodes. A range of cylindrical curvatures are available. 

Curved mirrors with through holes are useful in Raman spectroscopy and multi-pass cells. Surface form is maintained over the entire surface.

Using spherical mirrors in carefully optimized designs can offer large savings over aspheric optics. 

Curved mirrors are available from a wide range of materials and with various coatings.
