Laser Processes: Galvo-Scanning and Fast Steering Mirrors by Optosic®

Mersen high speed mirrors enable a game-change in the laser scanner industry through the physical characteristics, performance and cost benefits of SiC material.

It brings together two cutting-edge technologies:

• Boostec^® SiC material combined with
• optoSiC^® unique Know-How of optical laser scanner techniques and component technologies.

Mersen manufactures a range of standard Generic XY laser galvo scanning mirrors from 10mm to 100mm apertures for single pair consumption with a range of high-quality reflective coatings.

Our customers have the option to get the mirrors with and without a glued mount in all standard shaft sizes. Furthermore, we are able to manufacture in accordance to customer specifications. OEM products in different grades of SiC up to 500mm and more in geometry are available on request.

optoSiC^® steering mirrors are designed for a variety of tip-tilt applications. These mirrors are manufactured as optoSiC+ grade, a unique Silicon Carbide, to give optimum stiffness, dynamic flatness and high resonant frequencies under high torque loadings.

Our unique solution offers very low Moment of Inertia for all moving applications where processing speed and precise performance is paramount.

optoSiC^® steering mirrors are standard polished to interferometric controlled reflective-wavefront-error of e.g. 1/2*λ PV @632,8nm, (2*λ….1/8λ on request). Furthermore, we are able to manufacture in accordance to customer specifications.

Mersen manufactures high-performance laser galvo scanning mirrors from 10mm to 500mm apertures for single pair consumption with a range of high reflective coatings.

Sintered SiC is the base material for light and agile mirrors

• High stiffness
• Ultra-light weight
• Low moment of inertia
• High resonant frequency
• Thermal stability
• Low dynamic flatness PV
• Nontoxic (Beryllium replacement)

Mersen high speed mirrors are used and established into high-end markets

• Geodesy
• Airborne and Space scanning systems
• High power Laser material processing UV-IR, such as machining, marking, additive manufacturing
• Metrology and wafer inspection
• Bio / medical ophthalmology
• Streak cameras, targeting applications
• Security
• Sensing applications LIDAR

optoSiC^® core knowledge comes directly from the laser galvo-scanning industry, and a deep understanding of the needs of laser system, scan head and optical designers, and the system processing limitations generated by the performance bottleneck using conventional scanning optics.

Most importantly, by understanding a large variation of laser application solutions, this gives us the expertise to understand how to develop ultra-high-performance optics specific to applied use.
