Auto Focus (TTL type)

The TTL method is a built-in laser diode radiates to surface of works through an objective lens, and optical sensor receives its reflected beam also through the objective lens and detects the difference from graticule.

[Characteristics]
● High speed tracking with real-time adjustment the focus by only moving the objective lens.
● The Laser TTL method focusing system can be used for glass and film inspection.
● Small and compact make it easy to be integrated into an inspection equipment system.
● Supports 1/2-inch or less CCD camera (C mount).
