The Bioshutter II is an autonomous underwater shutter attachment designed for use with Satlantic radiometers. The primary purpose of the shutter is to prevent marine bio-fouling of the sensor optics in moored, time-series applications. Copper, and copper-based alloys have long been known to have good resistance against bio fouling and have been used in a diverse variety of commercial applications. Scientists working at the University of California Santa Barbara Ocean Physics Lab under the auspices of the National Ocean Partnership Programs’ (NOPP) Ocean-Systems for Chemical, Optical, and Physical Experiments (O-SCOPE) project developed an underwater shutter device for use with instruments such as Satlantic’s OCR-500 and HyperOCR series instruments. The Satlantic Bioshutter II device builds upon the success of this instrument by combining an innovative copper shutter and an input power controlled motor drive assembly to ensure robust operation in harsh marine environments.

Features:

• Restricts marine growth on sensor optics in moored applications
• Robust mechanical design  
• Completely autonomous - only external power required
• Simple operation – opens when power is applied, closes when power is removed 
•  Fast operation – 4 seconds to open, 6 seconds to close (typical)  
• Low current consumption (1 mAh to open shutter; 0.16 W thereafter)  
• User-selectable 180 degree (default) or 90 degree shutter movement
