Introduction
Near-Infrared (NIR) lenses and Short-Wave Infrared (SWIR) lenses are vital components in today’s high-performance imaging systems. Whether for industrial inspection, security surveillance, scientific research, or machine vision, these lenses enable precise imaging beyond the visible spectrum.
At VY Optoelectronics Co., Ltd., based in Changchun, Jilin Province, China, we specialize in custom optical lens design, infrared camera lens manufacturing, and precision lens assembly. Our C-mount NIR and SWIR fixed-focus lenses are trusted by clients worldwide for their optical quality, durability, and application-specific performance.
What is a Near-Infrared or SWIR Lens?
A Near-Infrared lens is optimized for wavelengths typically between 750–1400nm, while a Short-Wave Infrared lens covers 900–2500nm. Unlike standard visible-light optics, these lenses are designed for high transmission in infrared bands, reduced chromatic aberration, and stable performance under demanding conditions.
Common Applications
Industrial multi-band inspection (PCBs, lithium-ion batteries, semiconductors)
Security and surveillance (NIR night vision camera lens)
Scientific and agricultural imaging (crop health monitoring, spectral analysis)
SWIR detection (power line inspection, wafer inspection)
