Gates Ports

The SWP25B grants both 110 degree wide angle and full zoom-through capability. Never before could big creatures be captured at 110 degree field of view, then zoom to maximum telephoto and fill the frame with a mere 1.5 inch subject and everything in between. Further, the SWP25B can be used in both air and water, as well as split air/water images.

With an astounding 120 degree field of view this port will provide complete scrutiny of a Humpback from mere feet away. Yet the SWP44 includes full zoom through capability for crystal clear tight shots as well as macro of 4.5" / 115mm critters -- and everything in between. Unlike other optics that require diopters, or work only at zoom extremes, the SWP44 is designed for distortion free images throughout the entire zoom range.

with an astounding 120? maximum angular field of view this port will provide complete rectilinear imaging of Humpbacks from mere feet away. Yet the SWP44 includes full zoom through capability for crystal clear tight shots as well as macro critters -- and everything in between. Unlike other optics that require diopters, or work only at zoom extremes, the SWP44C is designed for distortion free images throughout the entire zoom range.

The WP25 is borne of Fathom Imaging expertise, designers of high accuracy optics for applications including precision laser, super high resolution digital imaging, and HDTV underwater video. The Fathom signature guarantees high resolution optics free of distortion, flare, vignetting and black spot reflections. Fathom ports are constructed entirely of high grade optical glass elements and coated with a proprietary High Efficiency Broad Band Anti-Reflective (HEBBAR) coating for maximum light transmission. All Fathom ports are then nitrogen purged/vacuum sealed in a dust-free environment, ensuring no foreign matter or condensation to spoil your image.

The WP35 is a distortion-free, hi resolution port for the VX2000 / PD150 and HD1 housings. Carrying the Fathom Signature a mark of excellence the WP35 is a member of Gates premium
line of underwater optics, and the world's finest.

Key Features

This port contains a single, flat, uncorrected element. The field of view becomes narrowed underwater, subject to the same refraction as a diver looking through a facemask. This Port allows full camera zoom capability, and diopters may be used to increase the magnification of a macro subject. +1, +2 and +4 are commonly used, and available from Gates as an accessory kit. This Port contains a single optical acrylic element that is forgiving to minor bumps and handling, and it is field replaceable.

This port contains a single, flat, uncorrected element and allows full camera zoom capability. Diopters may be used to increase the magnification of a macro subject. +1, +2 and +4 are commonly used, and available as an accessory kit.
This port has a resilient optical acrylic element for easy field replacement.

The Gates FP80 Flat Port is designed for use with the Gates Deep Red Video Housing. A port extension is required for this port to work properly.

The GM26 is a recent addition to the Gates Precision line of optics for underwater imaging. It is a +2.6 achromat diopter specifically for macro imaging.
This diopter is composed of two fused optical elements instead of the more common single element designs. This feature brings edge to edge sharpness to your macro images -- no 'keyhole' effect that has center sharpness but very fuzzy edges. Your macro images are clear and precise.
Focusable range (underwater): 12-15 inches from port vertex
Minimum image size @ full zoom and close focus: 1.05" x 0.75"

The Gates GP25A has a tough aluminum shell and a field replaceable optical polycarbonate dome. The field of view is approximately 70 degrees depending on the camera/port combination. This port is an ideal choice for extreme use conditions or when field replacement of a damaged dome is necessary.

The Gates GP32 wide angle port is compatible with the Gates HF S10. S100 and S11 housing.

The Gates Port Extender is for use with the Gates Deep Red Video Housing with the SP80 Standard Port.

The Gates Port Extender is for use with the Gates Deep Red Video Housing with Standard or Flat Port.

This port is optically corrected to provide a normalized view of the underwater world. It compensates for distortions or magnifications inherent to the underwater realm so the camera view below water is almost exactly that above water.
The Gates SP25 is made of optical polycarbonate and allows little or no zoom-through capability.

The Gates SP44 dome is field replaceable. Keep this replacement dome in your kit to replace damaged SP44 port domes.

The SP44 Standard Port (sometimes called a dome port) is optically corrected to provide a normalized view of the underwater world. That is, it compensates for distortions or magnifications inherent to the underwater realm so the camera view below water is almost exactly that above water. The SP44 is made of optical polycarbonate and allows little or no zoom-through capability.

The Gates SP80 Standard Port is an 8" port, designed specifically for the Gates Deep Red Video Housing for the Red One Cinema Camera. This port can be used with different lenses in conjunction with the required port extension.
