TAMRON Wide Band SWIR Lenses and Applications

Short wave infrared (SWIR) imaging is a specialized segment of machine vision, applying automated imaging outside the human-visible spectrum. Able to see through opaque plastic bottles to verify or control fill levels, inspect fruit for bruising, sort recyclables, inspect silicon wafers, etc., SWIR applications require SWIR-specific sensors, cameras, and lenses.

TAMRON Wide Band SWIR lenses are designed for Sony IMX990 / Sony IMX991 sensors and other sensors with a 5µm pixel-pitch. These wide band lenses feature the capability to work in a wide range of wavelengths from the visible range to Short-Wave Infrared Range (SWIR 400 – 1700nm). In addition, TAMRON’s new proprietary eBAND anti-reflection lens coating technology provides 80% constant spectrum transmittance over the whole visible to SWIR spectrum.
