TeleStar Plus Through-the-Lens (TTL) laser
Long Working Distance, High Resolution Interferometric Range Sensor
The TeleStar® Plus TTL laser has a unique interferometric sensing technology that yields a high measurement resolution, accuracy and capability in Fusion, SmartScope SP, and SmartScope Quest / Vantage systems. Additionally, the Telestar Plus TTL laser offers:
High resolution scanning – Interferometric sensing technology yields high measurement resolution, accuracy and capability
Measure deep surfaces – Very long working distance allows measurement of surfaces not accessible to other sensors; optional 0.45x lens yields a 200 mm working distance
TTL convenience – TeleStar Plus TTL laser is coaxial with system optics, allowing use over the full range of XY travel
Measure all surface textures – Ideal for measuring a wide range of part surfaces, from diffuse light scattering surfaces to translucent surface.

- 1. Measuring Range is the Z-range over which the performance of the sensor is linear and calibrated.
- 2. With spot size at best focus. Spot sizes for this particular laser are the full width of the spot at half maximum value (FWHM).
- 3. Using high quality specular (polished glass) surface, 1σ.
- 4. Accuracy/Repeatability of the laser on horizontal specular surfaces within the measuring range. System performance varies with machine type.
- Safety Considerations
This system is classified as a Class II laser device by IEC 825 (2001). Do not stare directly into the laser source.
