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

Infrared Optics IR Optics 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

LWIR Lens

Infrared Optics IR Optics 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

IR Optics 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.

Mid-Infrared Borescope Lens

Mid-Infrared Borescope Lens is an imaging instrument with customizable requirements for clear inspection of hard-to-access areas, such as boiler tubes, furnace walls, etc. The special environment must be considered in optical and mechanical design, especially the effect of high temperature on the lens. In some cases, customers also require light paths at certain angles in order to view the side wall.

Fisheye Lens

IR Optics Fisheye Lens

This is known as a Fisheye Lens because the front side of the lens seems like a bulging fisheye. Unlike ordinary lenses, the Fisheye Lenses have short focal lengths and a wide-angle field of view, allowing uniform screen brightness. It is used in various fields like Security Surveillance, Consumer Electronics, Automobiles and Testing Technology because it has steady focus.

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.
