Square window can be made of different materials according to customer needs, with or without AR.Widely used in laser protection, medical imaging, projection, etc.
Characteristics:
Shape: right angles on all sides, commonly square or rectangular.
Edge treatment: usually with chamfered or polished edges to prevent chipping.
Material: Optical glass (e.g. K9, fused silica), crystals (ZnSe, CaF₂) or infrared materials (Ge, Si) are commonly used.
Advantages:
(1) High space utilization: more space-saving in rectangular optical paths or systems that require close alignment (e.g. laser arrays, fiber coupling).
(2) Easy to fix: Right-angled edges are easy to position with mechanical fixtures and are suitable for integration into modular devices.
(3) Flexible cutting: can be cut from large size substrates, reducing material waste.
