Ideal for camping, spelunking, and observing nighttime creatures, the Bushnell night-vision goggles are a must for people who are just getting started after dark. The goggles set the standard in light-gathering technology, with a built-in infrared illuminator that enhances images even in the darkest shadows. As a result, the goggles are not only handy for casual use, but also for patrolling warehouses or performing surveillance where no ambient light exists. The goggles also come with a secure headgear system that wears comfortably throughout the evening.
How Does Digital Night Vision Work?
Bushnell digital night vision products collect existing light through the objective lens, and then process it through a highly sensitive image sensor. Inside the sensor, a photocathode is "excited" by the light and converts the energy into electrons. The electrons then accelerate across an electrostatic field inside the intensifier and strike a phosphor screen (like a monochrome TV screen), which subsequently emits an image that you can see. The acceleration of electrons provides gain and enhances the image. The infrared illuminator in this set of goggles adds to the function by providing a light source for the system to amplify. This, in turn, yields enhanced images in extreme low-light conditions where no ambient light is available for amplification, such as caves.
