Product Description

Optical Visible Light N-BK7/H-K9L Fairing Dome Lens for Telescopic Sight

Dome Lenses
Dome Lens are hemispheres. The two optical surfaces are an equal thickness apart, creating a naturally strong shape that gets tougher under pressure.A Dome is Widely used in deep sea exploration and national defence science and technology.We can produce all kinds of optical lenses according to customer's need, and we also have R&D department to design according to customer's requirement.
Silicon (Si) lenses and windows are an ideal choice for applications using wavelengths in the near-IR range and parts of the mid-IR range. Silicon offers high thermal conductivity and low density, making it suitable for laser mirrors. However, since silicon has a strong absorption band at 9 µm, it is not suitable for use with CO2 laser transmission applications. Silicon optics are also particularly well suited for imaging, biomedical, and other applications.
