Near-infrared cameras based on InGaAs
sensors have found wide use in industrial inspection,
telecommunications, thermal monitoring and research. To address the
special requirements of this optical band, Optec has designed a large
selection of lenses optimized for both the wavelengths properties of the
sensors used to detect them.

Features of Optec
SWIR Lenses
The SWIR band most often used extends over the 900-1700 nm range.
In some cases, the long wavelength end of the band may extend to
2500 or even 3000 nm. Optec offers lenses to cover all of these
ranges. All Optec SWIR lenses share these features: |
 |
- Antireflectance coatings
optimized for high SWIR transmission
- Designs using new non-toxic
glasses
- Low chromatic aberration
across the SWIR band
- Long back focal distance for
ease of camera design
- Rugged construction of focus
and iris mechanisms for long life
- Resolution matched to imager pixels for low aliasing

Optec offers a broad selection of SWIR lenses for
general and specialized applications. The new series are ideal for use
with larger sensors and smaller pixels. All of these lenses are
available coated for 900-1700nm, 1700-2300nm or 900-2300nm use.
