Forensic LiDAR and “engineering grade” or “survey grade” LiDAR (LASER Scanning) are very different things. Applications in which engineering and survey LiDAR conventions are manifestly deficient include litigation and its ADR cousins (mediation, arbitration, etc.).
For the FLIR T10xx camera series lenses typically offer very low focal length ratios. The common 36mm/28°HFOV lens aperture is fixed at f1.15, while the less common 83.4mm/12°HFOV lens is fixed at f1.2.
