Knight Optical’s BK7 Windows for Traffic Monitoring LiDAR Systems
23 Aug 2020
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.
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
Coatings: Antireflective (AR) coating options to meet your wavelength requirements
