OGP® TTL Laser
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) design | Laser and lens are coaxial, meaning measurements can be made throughout the system’s entire XY travel range |
| Coaxial lens and laser | Laser allows video imaging of part where the laser will operate |
| Large working distance | Increased working distance of 38 mm allows measurements of larger parts and part surfaces that may be recessed |
| Coincident laser and video | Common 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 laser | Laser can be configured for a higher speed or a higher resolution, depending on measurement requirements |
| Through-the-lens (TTL) design | Laser and lens are coaxial, meaning measurements can be made throughout the system’s entire XY travel range |
| Large working distance | 38 mm of working distance is large enough to focus on part surfaces that are recessed |
| Coincident laser and video | Common 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 technology | Incident 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 source | TTL laser sensor is ideal for measuring diffuse “scattering” surfaces and machined metal parts |
| Larger working distance | Measure recessed surfaces as much as 200 mm deep without fear of crashing into the part or fixture |
| Coincident laser and video | Common optical path allows users to switch between video and laser measurements almost instantaneously when measuring parts |
