Port Options
At this time of publication Gates SP80 Dome
(8” size), SP80-10 (10” size), SP110-10
(10” size for SPR110) and FP80 Flat Port options are available for the ALEXA 35
Housing. When choosing a Port consider the following tradeoffs and limitations.
NOTE
:
The optical interaction between any given lens and a Dome or Flat Port is
unpredictable. Distortions and aberrations can occur with either port. As such,
Gates does not warrant optical performance or image quality.
Gates endeavors to collect data from the field and our own testing as a resource to
customers, but you should always characterize your lens of choice for use
underwater.
Dome Port
✓
Optical material: Optical-grade acrylic or anti-reflective coated glass.
✓
Purpose: Wide to super wide imaging.
✓
Advantages:
✓
Retains FOV. Corrects for field of view distortions inherent in Flat Ports.
✓
Wide FOV capable. Up to 180 degree fisheye are possible depending on the
camera lens capability.
✓
Disadvantages:
✓
Little or no zoom. Domes inherently limit zoom through and varies with camera
lens employed.
