Product Description

Opticall N-BK7/sapphire/CaF2 drilling windows/cube for laser imaging system


BK7.H-K9L(N-BK7) is a RoHS-compliant borosilicate crown glass. It provides excellent transmission in the visible and near infrared
portions of the spectrum(350 nm - 2.0 µm). It is typically chosen whenever the additional benefits of UV fused silica.
H-K9L(N-BK7) is probably the most common optical glass used in high-quality optical components. H-K9L(N-BK7) is a hard glass that can withstand a variety of physical and chemical stressors. It is relatively scratch and chemical resistant. It also has a low
bubble and inclusion content, making it a useful glass for precision lenses.
CaF2 Calcium Fluoride has good performance at optical and thermo-mechanical properties,it can be used for optical Windows,spherical
lens, prisms and cylinders within a wide range from 130nm to 9μm. It has optical properties of isotropy, low absorption and low
refractive index, which made CaF2 gain the unique advantages in the application.
Sapphire (Al2O3) has exceptional surface hardness and can only be scratched by a few materials other than itself. This hardness allows it to be made into much thinner optics than other substrates. Sapphire is chemically inert and insoluble to water, common acids, and alkalis for temperatures up to 1,000 °C. Sapphire is transparent in the UV to the IR (150 nm - 4.5 µm). It is commonly used in IR laser systems and has an ordinary refractive index of 1.754 and an extraordinary refractive index of 1.747 at 1.064 µm.
