The FLIR Apollo introduces thermal imaging to any standard daytime optic—no rezeroing needed. Fastened in front of a magnified sight via Picatinny quick-release mount, the Apollo brings state-of-the-art thermal technology to an existing set-up in seconds. Detect targets in complete darkness or through atmospheric obscurants without the need to remove daytime optics.

Fast, On-Demand Thermal Imaging

  • No Rezeroing Required

    Clip-on thermal sight relies on the day scope reticle, eliminating the need to rezero.

  • Familiar Precision

    Front-mounted thermal sight allows consistent shooting position and eye relief with an existing day scope.

  • Advanced Imaging

    FLIR Tau 2 thermal core, advanced image processing, and HD AMOLED SVGA display create a bright, sharp picture.
