The TTL (through-the-lens) laser is completely integrated within optical systems of certain SmartScope® multisensor metrology machines. Scanning the laser spot over a surface provides detailed surface contours as part of a multisensor measurement routine.
TTL laser light is projected through the imaging optics to the surface being measured. The light reflects from the part surface through the lens into a dedicated detector. The steep imaging angle of TTL laser provides access to surface features that are recessed or located adjacent to vertical surfaces.
