Silver Circular Plano Mirrors, Standard Quality
LINOS® Silver circular plano mirrors in standard quality deliver reliable high-performance reflection suitable for a wide range of optical applications. Featuring a silver front-surface coating (RAGV), these mirrors achieve highest reflectance from 500 nm to 12 µm without absorption bands, ensuring consistent optical performance. Designed from low-expansion substrates, these mirrors maintain excellent thermal stability and surface flatness, minimizing distortion under varying environmental conditions. The double dielectric protection layer enhances durability and resistance to environmental influences, extending operational life span. These mirrors are also suitable for short-pulse (fs) applications, offering a combination of precision, reliability, and versatility.
Silver Circular Plano Mirrors feature a circular design for flexible integration into various optical setups. This configuration is suitable for laboratory research, spectroscopy, laser systems, and industrial optics applications that demand stable, high-reflectance components for consistent long-term performance.
