UV-VIS-NIR and Optical Enhancement
• Image enhancement - This works by collecting the tiny amountsof light, including the lower portion of the infrared light spectrum,that are present but may be imperceptible to our eyes, andamplifying it to the point that we can easily observe the image.
• Near-infrared (near-IR) - Closest to visible light, near-IR haswavelengths that range from 0.7 to 1.3 microns, or 700 billionthsto 1,300 billionths of a meter.

How Night Vision scopes work
• Night Vision scopes and binoculars"amplify" existing light, allowing you tosee in conditions otherwise too dark forthe naked eye.
• Available light (photons) is collected bythe objective lens and focused on thefunctional heart of the device, the imageintensifier.
• Inside the intensifier, a photocathode is"excited" by the light and converts thephoton energy into electrons. Theseelectrons accelerate across anelectrostatic field inside the intensifierand strike a phosphor screen (like agreen monochrome TV screen) whichemits an image that you can see.
• It is the acceleration of electrons whichprovides gain and enhances the image.

Three Generations of Night Vision Goggles
• Generation 1 - Developed in 60s only works underfull moon. Considered obsolete.
• Generation 2 - Can work under partial moonlight.Has poor signal to noise ratio.
• Generation 3 - Gallium Arsenide (GaAs)photocathode sensitive to light beyond 800 nm,considered to be the critical near-infrared regionwhere the night sky illuminance levels are thegreatest

Solution: How to stay unseen
• An enhanced polymer technology hasbeen developed that is tailored tomeet the near-infrared environment.The polymer fiber uses micron sizeparticles that aborb the wavelengthsin the same manner as itsurroundings.
• This new and innovated polymer isengineered to work in fibers indaylight and night.
