Quantum Composers

The AF910 is a cost-effective solution for systems used in the fields of laser micromachining, industrial micromilling, medical component devices, rapid surface pattern and thin-filmed scribing. Quantum Composers has developed an OEM auto focus solution with the following features:

* High intensity laser diode @ 685nm to accommodate surfaces that may vary in reflectivity.

* The system has the ability to dynamically adjust the laser diode intensity to maintain the optimal signal to noise ratio.

* Integrated motor control that includes step, direction and limit inputs.

* High resolution sensor: maintaining better accuracy and repeatability of the focus target.

* High speed DSP based microprocessor.

* Serial communications with selectable baud rates.

* Ability to change baud rates so that existing systems can communicate with the module.

* Up to 7 different objective configurations.

* +/-10V analog output focus level signal.

* Digital I/O for various system states and control.

* Dual focus plane support option.

* High update rate of 1KHz to maximize response times and throughput.

* Various interface modules to accommodate almost any electrical connection requirement.

* Custom interfaces: eliminating the need to redesign existing electrical interfaces.

* Optimized for patterned surfaces to avoid "false focus" conditions.
