Knight Optical’s BK7 Windows for Traffic Monitoring LiDAR Systems

27 Oct 2022

Here at Knight Optical, we offer a range of stock and custom-made BK7 (or equivalent) Windows for use within a range of LiDAR-driven applications, such as Traffic Monitoring Systems. 

As a substrate, BK7 (or equivalent) is one of the most widely used optical glasses for use in the visible range up to the near-infrared (NIR). This makes our BK7 (or equivalent) Windows ideally suited for Traffic Monitoring LiDAR systems, particularly those that operate at 1500-1560nm and between 850nm and 940nm. 

BK7 (or equivalent) can offer an uncoated average transmission of 92% between 300nm and 2000nm. Additionally, it is a cost-effective precision glass (part of the Borosilicate family) which; therefore, ensures you have a fit-for-purpose window. Our stock sizes range from 5-75mm diameter and between 1.5-8mm-thick. What's more, custom shapes and sizes available for quotation and we also edge stock down to smaller diameters, square and rectangular apertures.

Typical specs:

Material: N-BK7 (or equivalent), UV Fused Silica (UVFS), Quartz

Diameter tolerance: +0.0/-0.15 mm

Length/width tolerance: +/- 0.10mm

Thickness tolerance: +/-0.10mm

Transmission: Tavg=92% dependant on substrate thickness

Surface quality: <20-10 scratch/dig

Coatings: Antireflective (AR) coating options to meet your wavelength requirements
