OIS - Model 3883 -Auto-Exposure Vehicle Strobe
The Model 3883 Strobe is a smaller strobe intended for applications that require periodic images. It is not intended for applications that would require continuous repetition rates faster than 7 seconds. It is optimized for small size and weight, and is thus most suited for ROV, AUV, Pogo or manned submersible applications requiring a few hundred images per deployment. For more rigorous applications use the Model 3831 strobe.
The Ocean Imaging Systems Model 3883 Vehicle Strobe provides either externally powered or self-contained rechargable underwater strobe capablities for use in attended (ROV or tow sled) or autonomous (via external programmer or bottom-contact switch) applications for both shallow (2000 meter) and deep (6000 meter) still-imaging applications.
The strobe provides 100WS flash energy with recycle time as fast as 3 second. The 3883 exposure quench circuitry permits use with the through-the-lens (TTL) exposure monitoring found on select digital camera such as the OIS Model 4400 Digital Still Camera or other cameras using Nikon’s strobe sync. The strobe can also be used as a normal flash with non-TTL-capable film and digital cameras.
Both integral and remote-head versions are available for either shallow or deep-water applications.
Separation of the flash head from the strobe electronics in the remote-head version permits its installation at any point on the vehicle.
