Steve Kinney, Smart Vision Lights’ Western Sales Manager, kicked off Imaging and Machine Vision Europe’s (IMVE’s) recent webinar series on new technologies for infrared imaging with a presentation titled “An Introduction to Short-Wave Infrared Imaging (SWIR).”
Ranging from 1050 nm to 2500 nm, SWIR wavelengths are not visible to the human eye. But they work in a similar manner as visible wavelengths in that they are reflected by an object under inspection. This allows for a strong contrast when imaging objects, which is essential for high-resolution imaging used in machine vision applications.
Use of SWIR imaging is finding increasing application in machine vision because it significantly extends the image capture and analysis possibilities enabled by visible sensors. A key part of the technology’s adoption is the recent emergence of narrowband high-power SWIR LEDs, which offer a flexible alternative to conventional broadband SWIR sources. Emitting at peak wavelengths of 1050, 1200, 1300, 1450, and 1550 nm, these LEDs share identical configurations as visible LED lighting, greatly simplifying the adoption and setup of SWIR inspection schemes.
