Quantum Composers AF910 Specification

Autofocus AF910

The Quantum Composers Autofocus AF910 combines a
proprietary optical configuration with flexible interface
architecture to provide a robust autofocus for OEM
applications utilizing infinity corrected objectives.

The AF910 can be used on most surfaces:

• Low and high reflectivity

• Specular and diffuse

• Transparent and opaque

Includes patterned surfaces such as TFT arrays,
semiconductors and PCBs.

The AF910 provides various interface options:

• RS 232

• Analog output

• Step/ Direction motor drive control

• In focus, in range status, edge detect status

An optional interface adapter may be included which allows

for custom electrical interfaces. The sensor I/O signals can

be broken out into separate connectors, allowing for
integration into existing systems.

Serial communications provides configuration, status and

control of the sensor. The sensor can store up to 7
configurations, each optimized for a different objective.
