Absorbcijski filtri blokirajo vidno svetlobo in prepuščajo le infrardeče valove z dolgimi valovi ali ultravijolične valove z kratkimi valovi.
IR prepustni filtri so pogosti v planetarni fotografiji, saj je v območju dolgih valov motenje zaradi zemeljske atmosfere manjše. Če je senzor kamere občutljiv na to območje dolgih valov, bo slika bolj ostra kot v vidnem spektru.
