Silicon opical window
- Transmission from 1.2 – 7μm
- Available Uncoated or AR Coated for 1.65 – 5μm
- Ideal for Weight Sensitive Applications
Silicon Optical Windows are ideal for infrared applications, offering excellent transmission from 1.2 to 7 μm. They feature high thermal conductivity, low density, and a strong resistance to thermal shock, making them perfect for IR imaging and laser systems. These optical windows are commonly used in aerospace, defense, and industrial applications. Silicon windows can be AR-coated to enhance transmission and reduce reflection. Custom sizes and coatings are available to meet specific optical requirements.
