Knight Optical's BK7 Windows for Wind LiDAR Systems

26 Jun 2017

Knight Optical offer a range of Stock BK7 Windows, for use within Wind Monitoring LiDAR Systems. These LiDAR systems are used in monitoring wind speeds and wind direction. The data accumulated can be used to generate a Digital Terrain Model or a Digital Elevation Model which are 3D representations of terrain.

BK7 is one of the most widely used optical glasses available for use in the range from visible up to the near infrared. Making it ideal as a protective window for Wind LiDAR systems which operate at 1500-1560nm. The BK7 can offer an uncoated average transmission of 92% between 300nm and 2000nm.

Additionally the BK7 is a cost effective precision glass, part of the borosilicate family, which therefore ensures you have a window fit for purpose.

Stock sizes from 5mm to 75mm diameter; between 1.5mm – 8mm thick.
Custom shapes and sizes available to quotation.
Edging down to smaller diameters, square and rectangular apertures.
