Advanced Spectral Data Acquisition Software - BWSpec® Software

B&W Tek offers an advanced spectral data acquisition software called BWSpec®, which serves as the foundation for the company’s spectrometer software platforms.

All B&K Tek products are integrated with the BWSpec® software. These products include systems, spectrometers, and other accessories. The software includes a host of features that are designed to perform complicated measurements and calculations, thereby making it suitable for a variety of applications. Other features include multiple data formats and the capability to improve scanning parameters, for instance laser output power control and integration time.

Besides data acquisition and processing, other aspects like spectrum smoothing, manual/auto baseline correction and automatic dark removal are also included.
