Silicon carbide (SiC) Mirror

SiC is non-toxic and therefore a substitute for beryllium without a drop in dynamic performance

SiC mirrors: Precise optics for extreme requirements

Lightweight optics made of silicon carbide provide a perfect combination of material properties and polishing technology. This material offers high stiffness and thermal stability with good thermal properties. SiC is non-toxic and therefore a substitute for beryllium without compromising dynamic performance.

Maximum precision and robustness for your laser applications

Pleiger Laseroptik offers you SiC mirrors (silicon carbide) of the extra class, which are characterized by their outstanding properties. These mirrors are the perfect choice for applications that require highest precision, robustness and performance.

The most important advantages of SiC mirrors at a glance:

Extremely high dimensional stability: SiC has a very low coefficient of thermal expansion, which means that the mirror shape remains constant even at high temperatures .
High thermal conductivity: SiC conducts heat very well, which enables efficient cooling of the mirror.
Outstanding hardness and wear resistance: SiC is an extremely hard and resistant material that can withstand abrasive applications for a long time.
Good chemical resistance: SiC is resistant to most chemicals which enables it to be used in aggressive environments.
Lightweight construction: SiC is significantly lighter than other mirror materials, which simplifies handling and integration.

A wide range of applications:

SiC mirrors are suitable for a variety of applications in laser technology, e.g:

Laser processing: Cutting, welding, ablation, drilling
Laser material processing: Marking, engraving, structuring
Measurement technology: Interferometry, deflectometry
Optical systems: Lithography, microscopy, astronomy
Medical technology: Laser surgery, ophthalmology
