Congratulations on the purchase of your Bushnell Night Vision Product. Bushnell Night Vision products are comprised of high quality
image intensifier tubes and optics. Bushnell Night Vision products amplify existing light, allowing you to see in dark conditions too
dark for the naked eye.
HoW NIGHt VISIoN WorKS
Bushnell Night Vision products collect and amplify existing light through the objective lens, which is then focused on the image
intensifier. Inside the intensifier, a photocathode is "excited" by the light and converts the photon energy into electrons. These
electrons accelerate across an electrostatic field inside the intensifier and strike a phosphor screen (like a green monochrome TV
screen) which emits an image that you can see. It is the acceleration of electrons, which provides gain and enhances the image.
This is a Generation I device.
Your Night Vision device offers a Directional Sound Amplification System (DSAS), providing you with the added benefit of a highly
sophisticated sound amplification system. DSAS utilizes the latest developments in electronic sound amplification by combining our
exclusive high sensitivity DIRECTIONAL microphone with a state of the art noise reduction system, providing unparalleled sound
enhancement.
Your Night Vision device is ideal for a variety of professional and recreational uses including the following:
• Wild Life Observation
• Astronomy
• Boating / Marine Use
• Police / Law Enforcement
• Search and Rescue
• Security
• Property Management
