Q. Which of the following is not true about metrology lasers used in laser inspection?
  • (A) these are high-power instruments
  • (B) used for rapid non-contact gauging of delicate parts
  • (C) have low optical cross-talk
  • (D) wide dynamic range
💬 Discuss
✅ Correct Answer: (A) these are high-power instruments

Explanation: these are low-power instruments. laser systems have wide dynamic range, high contrast and low optical cross-talk. laser systems can be used in inspection of surfaces and in dimensional measurements and are very useful in precision and accuracy measurements.
