Co., Ltd. provides optical glass domes with commercial quality and high precision quality, including N-BK7 domes, Fused Silica domes, Sapphire domes and Silicon domes. The diameter of custom optical glass domes can be 15-280mm. The highest accuracy of concentricity can be less than 0.02mm. The highest accuracy of surface quality can be 40-20.

contact us N-BK7 has good transmittance (400nm-1550nm) in the visible and near-infrared spectrum. N-BK7 is a common optical material with low cost and high performance. The refractive index is highly consistent. There are fewer bubbles and streaks in N-BK7. N-BK7 domes are used for solar pyrgeometers to protect the detector from rain and snow. Besides, they prevent harsh environments from affecting the sensitivity of the detector.
