Key Features and Technical Specifications

The Silicon Carbide Reflective Mirrors are distinguished by their superior optical quality and durability. Below is a detailed specification table:

Surface Accuracy: The mirrors achieve a root mean square (RMS) surface error of better than 1/60 λ at 632.8 nm, ensuring minimal light distortion and exceptional image quality. This level of precision is critical in applications such as laser systems and optical metrology, where even minor imperfections can compromise performance.

Surface Roughness: With a surface roughness of less than 2.5 nm, these mirrors exhibit a smooth finish that minimizes scattering and enhances reflectivity. This characteristic is particularly important in high-energy laser systems and astronomical instruments, where surface quality directly impacts optical efficiency.
