Hard Gold Coated Copper Mirrors


LOM's high quality,  precision gold coated mirrors are manufactured to suit a broad range of applications. Gold mirrors offer very high reflectance over a wide infrared spectral range making them suitable  for imaging, scanning and as external zero phase-shift mirrors in CO2 laser material processing machines. LOM's robust gold coated mirrors will not delaminate or crack and offer excellent reliability and performance in relatively harsh and humid environments.  We offer a variety of shapes and sizes with relatively short leadtimes. Call LOM to discuss your unique requirements.

 

Applications -  Infrared imagining for medical, industrial and military applications; light weight scanning mirrors; marking lasers, direct and water cooled mirrors for high power CO2 lasers.
