Request InfoBrain Power Inc.Brain Power Inc.'s BPI spectrometer is a free-standing device with light sources that also can be attached to a PC via an RS-232 port. The instrument reads transmission wavelengths between 350 and 710 nm with better than 10-nm resolution and provides information on the visible and the UVA transmittance of the material under test, as well as the numerical Cielab color coordinates L*, a* and b*. Included software runs on Windows. The company says the instrument is compact and low in cost.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra June 2023 IssueThin-Film Metrology SystemThe kSA XRF (X-ray fluorescence) tool from k-Space measures film thicknesses below 100 nanometers for applications in coated glass and solar panels.
