100mm Diameter Optical BK7/K9 Window

What is a BK7/K9 Optical Window?

A BK7 window is a high-quality optical component.

With a diameter of 100mm, it provides a broad clear aperture for optical systems while maintaining excellent light transmission in the 350 nm to 2 μm range.

It is designed to serve as a protective barrier or transparent interfaces without altering the optical path.

It is worth noting that Bk7 is the same as K9.

Bk7 is an optical glass from an overseas series, while K9 is an optical glass produced domestically. Their characteristics are the same.

Key Advantages of the BK7 Window

• Large Clear Aperture: 100mm diameter provides wide coverage for high-precision optical systems.

• High Optical Transmission: Excellent clarity from visible to near-infrared wavelengths.

• Stable Refractive Index: Consistent performance across the aperture.

• High Surface Quality: Flatness and parallelism suitable for demanding optical setups.

• Cost-Effective: Superior optical performance at an affordable price compared with other glass types.

 

Applications of 100mm BK7 Windows

• Laser Systems
• Imaging & Detection Equipment
• Industrial Measurement Devices
• Scientific Research & Laboratory Instruments

 

Chenyu’s precision windows are highly suitable for industrial and low-power laser applications.

Their high-precision design minimizes beam distortion and scattering to the greatest extent.

The broadband coating option enables these precision windows to be applicable in the visible light and near-infrared spectral ranges.
