Product Description: A SWIR lens, or short wave infrared lens, is optimized for light in the 0.9 – 1.7μm
wavelength range. At Shanghai Optics we manufacture high quality SWIR lenses for surveillance, quality control, inspection and anti-counterfeiting imaging. Since ambient star light and background nightglow are natural providers of SWIR light, short wave infrared imagery is especially suited to night vision applications.
Our lenses feature the latest advancements in SWIR technology, and operate with less than 2 percent distortion. They have been designed to match InGaAs FPA formats, and are used in applications including solar cell testing, outdoor night vision imaging (for security applications), fruit surface scratches detection, silicone imaging, biomedical imaging, etc.
If a lens optimized for visible light is used in the SWIR range you will encounter high optical aberrations and the resulting images will have lower resolution. You can, however, use our SWIR short wave infrared lenses with visible light without degradation. We produce custom SWIR lenses for imaging applications that requires good quality images in visible, near infrared, and shortwave infrared spectral range. These lenses are specifically designed for installation into camera systems where they can generate high contrast images in various weather conditions including fog, dust, dawn, or night.
