Phasics SID4-HR High Resolution Wavefront Phase Sensor/Interferometeric Metrology Instrument

The Phasics SID4-HR is a high-resolution wavefront sensor designed for precise measurement and characterization of optical wavefronts and laser beams. Using Phasics’ patented quadriwave lateral-shearing interferometry technology, it provides full-field, high-dynamic-range phase and intensity maps in a compact, vibration-resistant form factor. The HR model offers finer spatial sampling than standard SID4 sensors, making it ideal for demanding metrology and adaptive optics applications.  *** NO Accessories

• Center (2 ports): Likely FireWire 800 (IEEE 1394b, 9-pin) connectors used for high-speed data transfer.
• Left circular connector: Appears to be a mini-DIN style connector (possibly for power or control, depending on the instrument configuration).
• Right circular connector: Appears to be a locking circular connector (likely for power or an auxiliary interface).

Key Features

This particular unit does not appear to have a standard RJ-45 Gigabit Ethernet port on the side shown in the photo. Instead, it looks to be equipped with dual FireWire 800 interfaces, which were commonly used for high-speed scientific cameras and instrumentation.
