Through the Lens (TTL) Laser
Through-the-Lens Lasers offer a non-contact method for measuring surfaces, using point focus for single-point measurements or scanning for multi-point measurements. TTL lasers offer:
TTL convenience – The TTL laser is coaxial with system optics, allowing use for measurement or as a laser pointer
Use with other sensors – Switch instantaneously between video and laser measurements
Long working distance – Scan surfaces without risk of striking a part or fixture
Auto tracking – The laser dynamically adjusts the Z-axis to track part contours automatically
Laser lens included – A laser lens that enhances laser and video performance is included
