High spatial resolution hyperspectral camera based on exponentially variable filter

Our customer Ingmar G. E. Renhorn recently published an article in Optical Engineering, 58 (10), 103106 (2019), https://doi.org/10.1117/1.OE.58.10.103106 that utilizes our most recent development, a continuously variable bandpass filter that features an exponential dispersion to obtain uniform sampling with respect to spectral resolution, i.e., a constant number of samples per spectral channel. At Delta Optical Thin Film we are  proud to contribute with our unique Bifrost Continuously Variable Filters to this innovative camera!
