Infrared Optics Catalogue
Infrared optics are used to collect, focus or collimate light in the near-infrared (NIR), short-wave infrared (SWIR), mid-wave infrared (MWIR) or long-wave infrared (LWIR) spectra. The wavelength of infrared optics is ranged between 700 – 16000nm. Wavelength Opto-Electronic offers various infrared optics such as thermal lens, athermal lens, zoom lens, objective lens, focusing lens, aspheric lens, free-form surfaces, off-axis parabolic mirror, window, filter and many more optical components of high performance to use in life-science, security, machine vision, thermal imaging, and industrial applications. We design, develop, prototype, manufacture, and assemble infrared systems with our in-house manufacturing unit using diamond turning with the laser-assisted tool, automated CNC polishing machines, coating, and customized metrology capabilities.
SWIR Lens
Shortwave Infrared (SWIR) wavelength band offers unique imaging advantages over visible and other thermal bands. It is quietly earning a growing place in industrial machine vision for electronic board inspection, material/food sorting, solar cells inspection, quality inspection and in military applications. SWIR lenses are utilized where other detectors or cameras are not sensitive enough for the finite detail recognition

MWIR Lens
Midwave Infrared (MWIR) achromatic lenses can be used by designers and researchers working in the 3µm to 5µm 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.

LWIR Lens
Longwave Infrared (LWIR) lens is typically uncooled and therefore, has less sensitivity. It allows the user to see through dust or smoke, which makes them particularly valuable in certain environments and applications. The field of view of a lens depends mainly on the focal length and the detector size.

Athermal Lens
The need to maintain focus over a wide range of environmental temperature is essential to the system performance, stability and high quality. Athermalized lenses kept it’s performance from changing by means of optical passivity, mechanical activity and mechanical passivity in a large temperature range. It’s configuration will auto-adjust itself when placed at different temperature.

Infrared Window is applied to isolate different physical environments while allowing light to pass through. When selecting windows, please consider the material, transmission, scattering, wavefront distortion, parallelism, and resistance to certain environment. We offer all kinds of windows which are made from different materials.

Infrared Filter
Bandpass Filter
Infrared Bandpass Filters come in two types, Narrow (up to 250nm bandwidth) and Wide Bandpass (more than 500nm bandwidth). On request, Wavelength Opto-Electronic offers bandpass filters of varying bandwidths, IR wavelengths, coatings, shapes, and sizes to meet the specific needs of the customer. These filters are used in Digital Imaging, Infrared Gas Analysis, Security Systems, High-temperature detection, and in several fields.

IR Filter (Bandpass) • 13/14
Longpass Filter
Infrared Longpass Filters transmit light higher than the cut-on wavelengths and attenuate the shorter wavelengths. Wavelength Opto-Electronic provides long pass filters of versatile coatings, cut-on wavelengths, sizes, and shapes in the infrared region. Customize infrared Longpass filters are also available. These filters are popularly used in Spectroscopy, Thermography, and Metrology & Device Engineering.
