SWIR Series Fixed Focal Length Imaging Lenses
• 3 Megapixel Designs
• Compact, Lightweight, COTS Imaging Lenses
TECHSPEC® SWIR Series Fixed Focal Length Imaging Lenses are
compact, lightweight SWIR lenses designed for applications operating
in the short-wave infrared (SWIR) spectra, ranging from 0,9 - 1,7
μm. These lenses feature SWIR-optimized optical designs, glass types,
and AR coatings from 0,8 - 1,8 μm. Designed for high throughput and
superior performance, the SWIR Series lenses are commercial-off-the
shelf (COTS) lenses with low f/#’s, covering large 25 mm sensors.
TECHSPEC® SWIR Series Fixed Focal Length Lenses are ideal for a
range of applications including inspection, sorting, and quality control.

What is SWIR?
Short-Wave Infrared (SWIR) light is typically defined as light in the 0,9 - 1,7
μm wavelength range, but can also be classified from 0,7 - 2,5 μm. Since
silicon sensors have an upper limit of approximately 1,0μm, SWIR imaging
requires unique components capable of performing in the SWIR range.
Indium Gallium Arsenide (InGaAs) sensors are the primary sensors used in
SWIR, covering the typical SWIR band, but can extend as low as 550 nm to
as high as 2,5 μm. Although linear line-scan InGaAs sensors are commercially
available, area scan InGaAs sensors are typically ITAR restricted, but
are available for a number of commercial applications with proper licenses.
SWIR imaging lenses are specially designed, optimized, and anti-reflection
coated for SWIR wavelengths.
Why use SWIR?
Unlike Mid-Wave Infrared (MWIR) and Long-Wave Infrared (LWIR) light,
which is emitted from the object itself, SWIR is similar to visible light in
that photons are reflected or absorbed by an object, providing the strong
contrast needed for higher resolution imaging. Ambient star light and
background radiance (nightglow) are natural emitters of SWIR and provide
excellent illumination for outdoor, nighttime imaging.
It is essential to use a lens that is both designed and coated for the SWIR
wavelength band. Using a lens designed for the visible spectrum will result
in low resolution images and higher optical aberrations. Since SWIR wavelengths
transmit through glass, lenses and other optical components (filters,
windows, etc.) designed for SWIR can be manufactured using the same
techniques used for visible components, decreasing manufacturing cost and
enabling the use of protective windows and filters within a system.
A large number of applications that are difficult or impossible to perform
using visible light are possible using SWIR. When imaging in SWIR, water
vapor, fog, and certain materials such as silicon are transparent. Additionally,
colors that appear almost identical in the visible may be easily differentiated
