FLIR Night Vision & Thermal Optics

FLIR (now Teledyne FLIR) is one of the original commercial thermal-imaging brands and a long-standing supplier to defense and industrial markets. Consumer-facing thermal optics include the Breach PTQ136 thermal monocular, the ThermoSight Pro PTS233 weapon sight, and the Scion handheld thermal monocular. FLIR pricing is premium, and the brand's strength is sensor quality rather than feature breadth — FLIR scopes tend to have fewer software gimmicks than ATN or Pulsar but cleaner thermal images. Best for users who prioritize image quality and brand legacy.
