For cost reasons, Short Wavelength Infrared (SWIR) instruments often incorporate off-the-shelf visible lens with an AR coating for the SWIR waveband. Such lenses unfortunately do not account for the way that glass transmits in the SWIR region and the final image quality is often compromised. Working closely with manufacturers of agricultural sorting systems – Resolve Optics has a proven track record of designing and supplying custom SWIR lenses that significantly improve both the resolution and imaging contrast achievable with these products.
