The global Short Wavelength Infra-Red (SWIR) Lenses market was valued at US$ 41.6 million in 2024 and is anticipated to reach US$ 79.7 million by 2031, witnessing a CAGR of 10.3% during the forecast period 2025-2031.
Short Wavelength Infra-Red (SWIR) lenses refer to optical lenses that are designed to operate in the short wavelength infrared range of the electromagnetic spectrum. This region typically spans from approximately 1,000 to 2,500 nanometers (nm). SWIR lenses are specifically designed to capture and focus light in this wavelength range, enabling imaging and analysis of objects or scenes that emit or reflect SWIR light. The design and construction of SWIR lenses take into account the unique characteristics and challenges associated with operating in the SWIR range. They are often composed of special materials or coatings optimized for SWIR transmission and possess specific optical properties to ensure accurate focusing and minimal aberrations. SWIR lenses can be mounted on cameras or integrated into specialized imaging systems to enable various applications in fields such as remote sensing, machine vision, and thermal imaging.
