Description

Topographical view of the surface of a feature measured with a laser area scan.

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.

OGP offers a full line of TTL lasers that are designed specifically for SmartScope Flash™, SmartScope ZIP® and SmartScope Vantage™ systems.

• Flash TTL Laser

The Flash TTL laser can focus its light very precisely, providing a small spot size and accurate surface focus when measuring parts on OGP® SmartScope® Flash metrology systems.

Features:Benefits:
Through-the-lens (TTL) designLaser and lens are coaxial, meaning measurements can be made throughout the system’s entire XY travel range
Coaxial lens and laserLaser allows video imaging of part where the laser will operate
Large working distanceIncreased working distance of 38 mm allows measurements of larger parts and part surfaces that may be recessed
Coincident laser and videoCommon optical path allows users to switch between video and laser measurements almost instantaneously when measuring parts

• ZIP TTL Laser

The ZIP TTL laser available for OGP® SmartScope ZIP® systems supports two modes of operation: high speed and high resolution.

Features:Benefits:
Switchable two-mode laserLaser can be configured for a higher speed or a higher resolution, depending on measurement requirements
Through-the-lens (TTL) designLaser and lens are coaxial, meaning measurements can be made throughout the system’s entire XY travel range
Large working distance38 mm of working distance is large enough to focus on part surfaces that are recessed
Coincident laser and videoCommon optical path allows users to switch between video and laser measurements almost instantaneously when measuring parts

• TeleStar TTL Laser

The TeleStar® TTL laser has a unique interferometric sensing technology that yields high measurement resolution in OGP® SmartScope® Vantage™ systems.

Features:Benefits:
Interferometric laser technologyIncident and reflected light are coaxial, yielding high measurement performance/Capable of measuring areas on parts where light might be obscured using triangulation sensors
Infrared emitting light sourceTTL laser sensor is ideal for measuring diffuse “scattering” surfaces and machined metal parts
Larger working distanceMeasure recessed surfaces as much as 200 mm deep without fear of crashing into the part or fixture
Coincident laser and videoCommon optical path allows users to switch between video and laser measurements almost instantaneously when measuring parts
