360C Ultra Miniature Rotating Optical Chopper
Features
Scitec Instruments Model 360 optical chopper system consists of a chopper head, drive board, photochemically etched discs and an interconnecting cable. This optical chopper uses 30mm diameter discs. The drive board and chopping head have been designed to be as compact as possible. The small size of the chopping head allows positioning in areas where space is critical. As the system is designed for OEM use, each component is available separately.
• 10 Hz - 14,000 Hz standard chopping frequency range
• 30 mm diameter discs
• Photochemically etched non-magnetic discs
• Ultra compact chopper head
• Small size drive board
• Low cost, for OEM applications
