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 optical window for Wind LiDAR systems which operate at 1500-1560nm. The BK7 can offer an uncoated average transmission of 92% between 300nm and 2000nm.

The 6, 8 and 10fold Befort magnifiers have been THE magnifiers for precise reading for 30 years. All measuring magnifiers have metal engraved scales. The measuring plates are manufactured and surfacetreated individually using a special process. This timeconsuming precise manufacturing guarantees parallaxfree reading when the magnifier is directly positioned on the object to be measured.

Differentiation between ANSI and DIN / EN ANSI eyeglass blinds differ from DIN / EN eyeglass blinds in terms of pressure levels, sealing strips and materials. In German-speaking countries, glasses blind disks are also called blind disks or throttle disks. However, the English terms “spectacle blind”, “blind paddle” are also often used in Germany. Pressure ratings according to ANSI in lbs The following pressure levels for blind disks according to ANSI are available 150, 300, 600, 900 and 1500 lbs. Sealing strips The following forms of sealing strips are available: SMF, FF, RF and RTJ. Materials The steel materials A 516 GR 60 and A 516 GR 70 are available. In the stainless steel sector, the materials TP 304 / L, TP 316 / L and TP 312 are possible.
