Knife-Edge Beam Analyzer

Knife-Edge Beam Analyzer

Multiple Scanning Knife-Edge beam profiler

High precision beam diagnostics for CW lasers. A wide spectral range from deep UV through 2700nm.

Wide dynamic range, beam size measurements down to 2 µm size and up to 10mm with 0.1 µm resolution.

The new USB version offers enhanced operation of the BeamAnalyzer series, including: USB 2.0 interface, 12 bit device, high resolution sampling for all blades simultaneously, Windows 7 32 & 64 bit OS.
Data streaming via TCP/IP communication protocol or RS232.

ActiveX software for integration in customer’s application program is available.

The system is composed of an external USB 2.0 box, a measuring head, a set of 2xNG Schott colored filters (NG4, NG9) in housing for Si and UV-Si detectors, a mounting post, Windows application software on CD disk, carrying case.

Note: The product is also available with an older PCI interface (OS supported Windows XP/2000), 8 bit A/D card
