dst11-t193-air series

The product series dst11-t193-air combines the features and reliability of OsTech Laser- and TEC controllers with diode laser modules to a turn key laser source. It could be powered by an input voltage of 110~230VAC with power factor correction. Normally the optical power output is located at the back panel. The optical power could be chosen between up to 120W. Lasers are air cooled with TEC temperature control. Multiple laser protection features are incorporated.

As user interface we provide the front panel display, RS232 and an optical isolated analog interface. Cw and pulsed modes are supported. Typical rise time is 25µs, shorter rise times are achievable on request.

It is possible to provide your own laser diode to OsTech. Otherwise we choose the best suited laser for your application.

Any question or request are welcome to discuss with our engineers.
