Beyond Visible: How SWIR + ViSWIR Lenses Unlock Hidden Signals for Machine VisionIf you work in machine vision, you’ve probably felt the limits of visible-light imaging—glare, opaque housings, look‑alike materials, or fog that swallows contrast. Short-Wave Infrared (SWIR), especially when paired with InGaAs sensors and purpose-built optics like Computar’s ViSWIR series, gives us a different kind of signal: contrast from chemistry, transmission through silicon and hard plastics, and resilience against haze. Think of it as turning on a new layer in the scene—suddenly, the “invisible” becomes a dataset.
