Environmentally Protected Camera/Lens Enclosure
E-O Imaging's camera/lens enclosures are designed to protect your imaging investment and assure its long-term reliability. The camera and its lens is assembled and tested at the E-O Imaging factory, then fitted into an enclosure. The enclosure is then sealed and pressurized with dry nitrogen to keep out moisture, pollution, chemicals, salt, and grime.

| Why use an enclosure? |
|
Environmental enclosures are designed to protect your imaging investment and assure the long-term reliability of your camera/lens assembly. The camera and its lens is assembled and tested at the E-O Imaging factory, then fitted into an enclosure. The enclosure is then sealed and pressurized with dry nitrogen to keep out moisture, pollution, chemicals, salt, and grime.
Enclosures will also retard image degradation. Unsealed housings allow small amounts of carbon monoxide, carbon dioxide, sulfuric acid and other oxidizers to accumulate on the camera and lens. The most noticeable effect of these chemicals, prior to camera failure, is the optical aberrations caused as the lens coating deteriorates. The internal construction is specifically designed to minimize hot spots, eliminate the need for mechanical cooling devices, and insure a clean, moisture-free environment. E-O Imaging's environmental enclosures offer automatic inductive heaters to assure reliable camera operation in extremely cold environments.
Another benefit of the factory sealed and pressurized housing is the assurance of a properly installed lens on the camera. The factory lens installation provides correct termination of lens wiring, including zoom and focus follower pots. All dust and debris is cleared from the optical path, which is essential for a blemish-free image. The lens is mounted, tested, and tracked. The camera and housing are shipped in one unit to the customer, ready to install.
