So how does night vision work?
Well in layman's terms it is fairly simple. You look through the one end when it's dark and 'voilą!' you can see through the other end. However for those more technically minded the answer is as follows:
Available light (energy) is collected is by the objective lens and focused on the image intensifier. Inside the intensifier a photocathode is excited by the light and converts the energy into electrons. The electrons accelerate across an electrostatic field inside the intensifier and strike a phosphor screen (like a monochrome tv screen) which emits an image that you can see. This acceleration of electrons provides gain and enhances the image. The Bushnell Moonlight Night Vision Scope is a compact lightweight and low-cost piece of equipment which makes night vision affordable for the most budget minded sportsman or woman. With its unique utilitarian design this monocular can be used effectively in a number of positions by both right and left handed people.
