Abstract: A substance component detection apparatus and a method are provided to reduce absorption of an infrared signal by a window medium, thereby obtaining abundant fingerprint region signals. The apparatus includes: a sample pool, an infrared optical window, an infrared light source, and a detector. The infrared optical window has a first surface that faces an inner side of the sample pool and that is configured to be in contact with a to-be-detected substance, and a second surface exposed on an outer side of the sample pool. A protruding portion is formed between two adjacent grooves on the second surface, and any protruding portion has an incident surface and an emergent surface. An infrared signal emitted by the infrared light source is irradiated on the incident surface. The detector determines a component of the to-be-detected substance and/or content of the component.
