Longwave infrared(LWIR)
LWIR imaging refers to imaging in the wavelength band approximately from 8μm to 12μm, and is important for applications ranging from defense, medicine and agriculture to environmental monitoring. In order to attain high transparency, conventional refractive lenses in the LWIR band require materials such as Silicon and Germanium.
The LWIR lenses from InfraOptics are a range of long-wave infrared lenses specifically designed to operate in the 8-14 μm wavelength range with uncooled detectors.
The lenses are designed with high image quality and large aperture (small F/#).
These lenses, are the perfect choice for a variety of applications, including temperature measurement for process quality control, predictive maintenance and medical imaging to give a few examples.
Midwave infrared(MWIR)
We provide our customer the most affordable solution without performance compromise.
The IR lens adopted the advanced technologies such as the latest optical design methods, special optical glass materials and special ferry films and materials, eliminating the focal plane deviation of visible light and infrared light.
The MWIR lens uses special optical glass materials as well as special ferry films and materials. The special optical glass material solves the problem of infrared corresponding clear imaging so that the light from the visible region to the infrared region can be obtained in the same focal plane position to achieve a clear image. Special crossing technology allows the infrared light to penetrate as far as possible. The multi-layer coating can also minimize the occurrence of ghost and flash in the backlight condition, and the high contrast quality can be obtained even under the bad conditions such as backlighting.
MWIR (midwave infrared) achromatic lenses can be used by designers and researchers working in the 3-µm to 5-µm spectral region. Providing near-diffraction-limited performance, these lenses are suitable for applications in FTIR (Fourier transform infrared) spectroscopy and MWIR thermal imaging, as well as for use with tunable quantum cascade lasers.
