Hi, my name is Kristina Kaszei a product support engineer at Edmund Optics. Today we will be discussing ghost images.
In optics, a ghost image is a faint second image caused by reflections within an optical component. One way you can experience this is when light propagating through an imaging lens and light reflecting off bounces back and focuses onto your camera's sensor. Most imaging lenses in our industry are designed and corrected to eliminate ghost images, but ghost images present in a system would have a direct impact on resolution and contrast in imaging.
Anti-reflection coatings can be applied to each lens surface to mitigate ghosting, but the cost of coatings can increase the cost of your overall system. If you'd like to learn more about ghost images, I encourage you to check out edmundoptics.com and view topics such as stray light, flare, and veiling glare. Thank you.
