Which unit is located to the right of the MSO-2 display and provides laser safety interlock for the FLIR 380-HD laser range finder and laser pointer?

• A. Laser Interlock Unit (LIU)
• B. Laser Safety Panel
• C. LIU Controller
• D. FLIR Interlock Module

Answer: (A)

The key idea here is laser safety interlock hardware — a dedicated unit that enforces safety by monitoring interlock signals for the laser devices and preventing operation unless it’s safe. The Laser Interlock Unit is the component designed to provide that interlock function specifically for the FLIR 380-HD laser range finder and laser pointer, and it is the unit typically located to the right of the MSO-2 display. It ensures the lasers can only activate when all safety conditions are met, and it will cut power or disable the laser if an interlock fault or safety condition is triggered.

The other options describe different roles: a Laser Safety Panel is mainly for warnings and general safety visibility rather than controlling laser on/off states; the LIU Controller would manage LIU operation but is not the interlock itself; and the FLIR Interlock Module would be part of the FLIR equipment, not the separate MSO-side interlock unit.
