MX-GCS sight polarity day to night switch engages which feature?

• A. IR NUC
• B. Day Vision
• C. Night Light
• D. Infrared Sensor

Answer: (A)

Switching from day to night on an infrared sight triggers a calibration called Non-Uniformity Correction. Infrared detectors are made of many individual pixels, and each one can respond a bit differently. When conditions change—like temperature shifts or mode changes during a day-to-night transition—the detector’s pixels no longer respond uniformly, which can make the image look blotchy. IR NUC applies per-pixel adjustments to offset and gain so every pixel lines up with the others, producing a clear, consistent image in both day and night. Some other options don’t capture this idea. Day Vision isn’t a corrective calibration, Night Light would imply adding illumination rather than calibrating the detector, and an Infrared Sensor is the hardware itself rather than the specific corrective feature engaged.
