Overview
Laserline GmbH provides industrial system solutions for laser materials processing, focusing on the integration of processing optics with diode lasers. The document discusses the OTZ Zoom Optics, which are designed to offer flexibility, dynamic adaptability, and modularity for various laser processing tasks.

Specifications
The OTZ Zoom Optics are available in three configurations: variable circular spots (OTZ-5 VC), variable line spots (OTZ-5 VL), and rectangular spots (OTZ-5 VR). These configurations allow for independent adjustment in the X and Y directions, maintaining homogeneous intensity distribution. The optics support laser powers up to 20,000 W and are equipped with motorized adjustments for precise control of spot radius, track width, and focus length.

Procedures and Applications
The OTZ Zoom Optics are particularly beneficial for applications such as laser hardening, heat conduction welding, keyhole welding, and cladding tasks. The system's flexibility allows for efficient processing by dynamically changing geometry during laser operations. Additional features include water cooling and integrated temperature sensors for continuous high-power operation.

Modularity and Integration
The OTZ-5 variants can be configured with OTS-5 modules, ensuring that the optics are tailored to specific process requirements. The system includes components such as optical fiber connectors, collimation elements, motorized zoom optics, and focusing lenses. Optional components like pyrometers, cameras, and powder nozzles can be integrated for enhanced process control.

Mechanical and Optical Specifications
The optics weigh less than 11 kg and have dimensions of 135 x 137 x 300 mm³. They support a maximum laser power of 20,000 W, with a numerical aperture of 0.1 or 0.2, and a focal length range of 200 - 600 mm. The system operates within an ambient temperature range of 10 - 45 °C and a maximum humidity of 85% non-condensing.

Options and Interfaces
The system offers various auxiliary components and interfaces, including pyrometers, CMOS cameras, and powder nozzles. It supports both analog and digital motor control interfaces, allowing easy integration into laser control systems.
