Small gold mirror on GaAs
 
 

If very small broadband mirrors with dimensions of only a few millimeters are needed then gold coated GaAs chips are appropriate. A single crystalline GaAs wafer as substrate for a reflecting gold layer has a very smooth surface and a good thermal conductivity of 55 W/(m*K). It can be cutted into small quadratic or rectangular chips.

We provide unmounted gold mirrors with a standard substrate thickness of 450 Ám
 
Available chip areas:
  • 4.0 mm x 4.0 mm
  • 2.0 mm x 2.0 mm
  • 1.3 mm x 1.3 mm
  • custom dimensions on request
 
Spectral reflectance

Gold mirrors can be used as broadband reflectors for wavelengths > 800 nm.
The reflectance increases continuously with increasing wavelength.
