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).
