Scanning mirrors are high-performance optical components designed for fast beam deflection and accurate positioning in two-axis laser scanning systems. They are essential elements in applications requiring high speed, precision, and thermal stability, such as laser marking, precision welding, and laser scanning.
Shape Optics Technologies Pte Ltd (SOT) scanning mirrors are manufactured using premium substrates including Silicon, BK7, and Fused Silica, ensuring excellent thermal conductivity, low inertia, and stable optical performance. These mirrors support a wide wavelength range, including 10.6 µm (CO₂ lasers), 2940 nm, 1064 nm, 650 nm, 532 nm, and 355 nm, making them suitable for CO₂, fiber, Nd:YAG, and UV laser systems.
With robust dielectric or metallic high-reflection coatings, SOT scanning mirrors maintain stable performance under continuous high-speed scanning and varying environmental conditions.
