Hyperspectral Imaging Hyperspectral imaging is a hybrid technique, combining spectroscopy and 2D imaging, and most recently 3D imaging. A hyperspectral image is generated by collecting and processing images of the sample within narrow spectral bands (typically between 10 and 100) covering a continuous spectral range. This method produces spectral data for each individual pixel in […]
We are proud to announce that our partner Ingmar Renhorn and his collaborators published the article High spatial resolution hyperspectral camera based on a linear variable filter in Optical Engineering. It can be openly accessed via http://opticalengineering.spiedigitallibrary.org/article.aspx?articleid=2587755. Read and share it! More information on the filters used for the work in this article.
Delta Optical Thin Film launches several LED and laser bandpass filters. They are optimized for specific LED and laser wavelengths and combine exceptionally large angular tolerance with high transmission and provide at least OD4 out-of-band rejection in a large wavelength range. This makes these filters well suited for machine vision applications with near-infrared LED illumination or Nd:YAG laser […]
Last month we invited you to send us your suggestions for a new name for our linear variable bandpass filters for Hyperspectral Imaging. The response was overwhelming, and many of you had brilliant and creative ideas. The name we chose is Bifrost. It was suggested by Martin from Norway.Rainbow filter was the most numerous and logical suggestion. […]
