Fiber laser and Near IR mirrors;

Infrared mirrors are used for many applications in the near infrared typically 800nm to 5um wavelength.

The growing application is for fiber laser metal cutting, and to some extent disc lasers. Fiber laser users find glass mirrors can fail with high power fiber lasers, and coatings optimised for 1064nm and Nd:YAG lasers may not funtion at 1070nm, 1073nm, and other wavelengths. Even so dust on the mirror face will cause a glass mirror to crack from the localised absorbed heat. Our reflective gold coating offers a broad consistent reflectivity in the infrared spectrum, perfect for fiber laser mirrors, as well as for reflecting broad band infrared radiation such as in IR spectroscopy, or where multi-wavelength, or tunable laser sources are used. The copper mirror substrate sinks away the heat from localised hot spots caused by absorbing debris.

OPO's (Optical Parametric Oscillators) are an area of research where gold coated mirrors can be used for multiple wavelength reflection.

Quantum Cascade Lasers (QCL) are developing rapidly, and our metal coated mirrors are being used in multi-pass systems such as Herriot Cells, White Cells for gas sensing, and spectroscopic multi pass gas analysis.

The chemical inertness of a gold plated mirror find uses in environmental monitoring of gases, such as in chimneys, flues, pipes, and of liquids where other mirror coatings would be destroyed.

Uncoated Molybdenum mirrors are very durable, inert, and can withstand high temperatures. Solid uncoated Molybdenum is the reflective surface of choice for the harshest of environments.

Repolishing and recoating of used mirrors can reduce replacement costs in systems where chemical attack is expected and frequent repacement of optics is needed.

In some applications uncoated polished Tungsten mirrors can solve optical problems, especially at high temperatures.

Polished Stainless steel mirrors are manufactured for pharmaceutical, foodstuff, brewing and nuclear industries where it is one of the few approved materials for use.
