InfraRED OPTICal LENSES
Optics Lens
A lens is a clear (transparent) object (like glass, plastic or even a drop of water) that changes the way things look by bending the light that goes through it. They may make things appear larger, smaller, or upside-down. Some places lenses are used include spectacles (eyeglasses), contact lenses, cameras, projectors, microscopes, telescopes, magnifying glasses, etc. Eyes are also considered lenses.

Germanium Lenses
are ideal for use in Mid-Wave Infrared and Long-Wave Infrared applications, including thermal imaging, spectroscopy, or FLIR. Due to thermal runaway, or the decrease in transmission as temperature increases, Germanium Lenses should be used at temperatures below 100°C. Germanium's high density (5.33 g/cm3) should be considered when designing for weight-sensitive systems.

Zinc Sulphide Lense :
Mechvac supply a range of quality Zinc Sulphide optical components including Zinc Sulphide lenses. Zinc Sulphide (ZnS) is a widely-used IR transmitting material used for windows, lenses and other optical components. The material transmits at about 50% between 0.4 -12μm before dropping off to zero transmission at around 15μm. Its low absorbance in the IR spectrum makes it suitable for CO2 lasers operating at 10.6μm. Zinc Sulphide has a pale yellow appearance and a hardness of HK160. Although the material is resistant to thermal shock, it is not recommended for harsh environments. Zinc Selenide is used in the form of optical windows in FLIR (Forward Looking Infrared) systems, as meniscus, spherical or cylindrical lenses and as resonator windows in CO2 lasers.
