Imaging the Sky with Linear-Variable Filter Technology

Video • December 16th, 2021

SPHEREx images the entire sky in over 100 bands across a key part of the infrared spectrum. Linear-Variable filter technology lets the telescope efficiently collect large quantities of both spectral and imaging data simultaneously. Since each pixel in the SPHEREx detector arrays measures a different infrared color, combing data taken across several exposures yields full imaging and spectral data for any galaxy or other target of interest on the sky.
