Does a Thermal Clip-On Replace the Day Optic?

No. A front-mounted thermal clip-on is designed to work together with an existing day optic. A dedicated thermal scope is a different architecture and replaces the primary viewing/sighting optic rather than operating as a front attachment.

Does a Thermal Clip-On Automatically Preserve the Existing Zero?

Clip-on systems are designed around preserving the existing day-optic workflow, but alignment and repeatability depend on the exact thermal device, adapter, mount, and installation. The manufacturer's verification procedure should be followed.

What Is the Difference Between Mechanical Alignment and Image Alignment?

Mechanical alignment describes the physical relationship between the clip-on, adapter, and day optic. Image alignment changes the position or orientation of the thermal image presented on the display. Some systems use both.

Does Higher Day-Scope Magnification Add Thermal Detail?

No. The day optic magnifies the clip-on's displayed thermal image. It does not increase the thermal detector's native resolution.

Is Flat-Field Correction the Same as Clip-On Calibration?

No. Flat-field correction addresses detector non-uniformity. Clip-on alignment or collimation addresses the relationship between the thermal image and the day optic.

Can Any Thermal Scope Be Used as a Front Clip-On?

No. Clip-on use should only be assumed when the device manufacturer explicitly supports that configuration and provides the appropriate optical, mechanical, and alignment architecture.
