Product Description

BK7 Optical Windows are one of the most common glass. It has a transmission range of 380nm ~ 2100nm. Optical Windows BK7( K9 ) has high homogeneity, no bubbles and low impurities, which can be used directly as transmission optical materials. BK7 has high hardness and good scratch resistance. However, the thermal expansion coefficient is large and is not recommended for temperature sensitive applications.

K9 Optical Windows has been used since long ago. It's a kind of optical windows which includes high precision and low precision. Although there are different types of BSC7 or BSL7 due to different manufacturers, they are basically the same because of the composition, optical properties, physical properties and chemical properties. In addition to a lens or a prism, it is also used in most Optical Elements, such as a mirror or a spectroscopic substrate or a variety of coated Optical Filters substrate. When selecting windows you should consider materials, transmission, scattering, wavefront distortion, parallelism and resistance to certain environment. Coupletech offers a wide range of different materials are available upon requirement. BK7 materials can be also used in Optical Lenses or Optical prisms.
