Silicon Wedge Plates

Product Overview
Silicon wedge plates are optical components with a unique wedge shape, designed to prevent interference effects (Etalon effect) caused by the reflections from the front and rear surfaces of high-parallelism windows. They also reduce optical feedback interference in the laser cavity, improving laser output stability and enhancing the performance of optical systems. The wedge-shaped design effectively minimizes interference from reflected beams, ensuring more stable light path transmission. Silicon wedge plates are typically manufactured using precision processing techniques, including cutting, grinding, and polishing, to ensure high surface quality and optical performance. They are often coated to improve transmission and reduce reflection, making them perform exceptionally well in a variety of optical systems.
