Goldflex™

Ultra efficient Broadband IR Gold Mirror

All types of optical sensing devices utilize light, which needs to be routed by mirrors. To optimize this, Goldflex™, a gold based metallic mirror is recommended. This gold mirror offers the broadest spectral range of any mirror. It is characterized by excellent reflectivity and lowest polarization dependence in IR-wavelength range. Although the reflectance is lower in the visible range, it is still greater than 90% at 633nm for beam steering with HeNe laser.

Benefits

Excellent environmental durability
Suited for applications with temperature sensitive substrates
EU RoHS directive compliant

Applications

Beamsteering/Scanning IR mirrors

Laser Processing systems
Construction & Logistics
Factory Automation
Metrology & Inspection
