What is a BK7 window?

The BK7 window is an optical component processed from high-quality optical glass BK7.

It is commonly used in optical systems as a protective window. The BK7 material has excellent light transmission properties, with a high transmittance in the wavelength range of 350nm to 2μm.

Moreover, it has good surface accuracy, high uniformity, and a relatively economical price.

Compared with materials such as fused quartz and sapphire, the BK7 window has extremely high cost-effectiveness in the application of visible light and near-infrared wavelengths,

People often choose them in laser systems, imaging equipment, photoelectric detectors, scientific experiments and industrial optical instruments.

What type of glass is BK7?

BK7 is a common high-quality optical glass, belonging to borosilicate crown glass.

Due to its excellent light transmission properties, mechanical strength and processing properties, ipeople often choose it in the manufacturing of various optical components.

In the wavelength range of 350 nm to 2 μm, BK7 exhibits high transmittance and stable optical properties.

BK7 is often used to manufacture optical components such as windows.
