H-K9L Glass Dome Window
Glass domes are hemispherical protective optical windows designed for applications requiring large-angle incident light coverage, widely used to safeguard detectors, optical sensors and other electronic and optical components.
Tuniu Optics supplies uncoated glass domes in multiple sizes with substrates of K9 optical glass and UV fused silica. Available diameters include 25 mm, 50 mm, 75 mm and 100 mm, with wall thickness ranging from 1 mm to 4 mm. K9 glass domes are suitable for visible and near-infrared applications, while UV fused silica domes deliver reliable performance for ultraviolet scenarios, fully meeting diverse application requirements.
