Request InfoCRAIC TechnologiesFor solar photovoltaic (PV) cell testing applications, Craic Technologies Inc. has unveiled the 20/20 Solar microspectrophotometer, which is designed to measure the thickness of thin films as well as the optical efficiencies and clarity of photovoltaic cells. This can be done by both transmission and reflectance, whether the solar cells are the traditional crystalline silicon substrates or one of the thin-film varieties. Protective glasses and concentrator modules also can be analyzed for their efficiency. The device can be combined with proprietary contamination imaging capabilities to...See full productRelated content from Photonics MediaPRODUCTSVision Spectra Summer 2022 IssueHyperspectral CameraThe Hyper-Cam Mini xLW from Telops Inc. is an advanced, compact, IR hyperspectral imaging system that combines high spatial, spectral, and temporal resolution for remote detection, identification,...Photonics.com 6/23/2023PhotosensitizersAlfa Chemistry’s photosensitizer line includes porphyrins, ketone, acridine, ruthenium, iridium photosensitizers, naphthoquinone, and other types for solar cells, catalysis, biomedicine, and...Photonics Spectra October 2022 IssueExplosion-Proof TDL SpectrometerAn explosion-proof TDLS8200 probe-type tunable diode laser spectrometer from Yokogawa Electric Corp. provides simultaneous measurement of oxygen and carbon monoxide or methane concentrations for...Photonics.com 4/21/2023Optical Metrology SoftwareThe Mx 9.1 software from Zygo Corp. integrates acquisition and data analysis for surface topography and wavefront data.
