In the realm of optical technology, achieving clarity across multiple wavelengths is a game-changer. Whether for surveillance, machine vision, or scientific research, the ability to capture sharp images in both visible and infrared (IR) light is critical. This is where IR corrected lenses come into play.
What is an IR Corrected Lens?
An IR corrected lens is a specialized optical component engineered to minimize focus shift when transitioning between visible and infrared wavelengths. Traditional lenses often suffer from chromatic aberration—a distortion caused by different wavelengths focusing at varying distances. This results in blurry images when using IR illumination, such as in low-light surveillance or thermal imaging.
IR corrected lenses address this issue by incorporating advanced design elements, such as specialized glass materials and multi-layer coatings, to ensure consistent focus across the spectrum. This makes them indispensable for applications requiring 24/7 operation, such as security cameras, night-vision systems, and industrial automation.
