IR Corrected Lens

An IR Corrected lens, also known as an infrared corrected lens, is a sophisticated type of optical lens that has been fine-tuned to provide clear and sharp images in both visible and infrared light spectrums. This is particularly important in surveillance cameras that operate around the clock, as typical lenses tend to lose focus when switching from daylight (visible light) to infrared illumination at night. When a conventional lens is exposed to infrared light, the different wavelengths of light do not converge at the same point after passing through the lens, leading to what is known as chromatic aberration. This results in out-of-focus images and degraded overall image quality when illuminated by IR light, especially at the peripheries.
