AR coating silica optical Sapphire Dome Lens for infrared thermal imaging camera
A dome is consist of two parallel curves surface, it is essentially
optical windows which doesn’t introduce any magnification to light
path. IR domes are often used in defense applications which has a
extreme environment, high optical transmission at specific IR
spectra and high hardness and flexural strength and durability are
several specifications must be considered in substrate materials
selection.
Advance offers infrared domes made of a variety substrate
materials: sapphire, hot-pressed MgF2, hot-pressed ZnS, ZnSe and
Germanin. While sapphire are ideal for both ultra-violet (UV) and
MWIR (3-5micro) band, hot-pressed MgF2 are good for MWIR band, and
ZnSe or Germanium are good choice for 3μm to 12μm domes covers both
MWIR and LWIR region.
