Ìhè na-acha uhie uhie abụghị ụdị infrared anyị na-ekwu. Infrared nke physics kọwapụtara bụ ụzarị ọkụ nke ihe nwere okpomọkụ. ebili mmiri electromagnetic, adịghị ahụ anya. Infrared na-agụnye ọkụ niile nwere ogologo ebili mmiri ka ọkụ na-acha uhie uhie, ebe laser na-ezo aka na ìhè nwere ụfọdụ ogologo ikuku. Ha abụọ enweghị njikọ dị mkpa ma ha esoghị n'otu mpaghara. Laser bụ ụzarị ọkụ a na-emepụta site na mmụba nke ikuku na-akpali akpali. Infrared bụ akụkụ nke ụdịdị dị iche iche nwere ugboro dị ala yana ogologo wavele ogologo nke anya gba ọtọ enweghị ike ịhụ ya. Ogologo ikuku sitere na 0.76 ruo 400 microns. Ntinye na mgbochi mgbochi nke ìhè dị njọ karịa nke laser, ya mere laser n'èzí dị mma karịa ọkụ uhie n'okpuru ọkụ siri ike.
