The present invention belongs to the technical field of infrared research and application in biomedicine. In particular, it refers to an apparatus of bio-effect system with the use of controllable infrared wave. The invention includes a shell (16) a infrared source (1) inside of the shell (16), the first group of filter mounting plate (2), convex lens (3), concave lens (4), the second groups of filter mounting plate (5), cable receptor device (6) and execution end (18) the first group of filter mounting plate (2) and the second group of filter mounting plate (5) are in line with the central axis the described convex lens (3) is installed between the infrared source (1) and concave lens (4) the described first group of filter mounting plate (2) and the second group of filter mounting plate (5) are located between the concave lens (4) and the cable receptor device (6) the described second group of filter mounting plate (2) is installed with the first filter (23) the second group of filter mounting plate (5) is installed with the second filter (7). The invention is simple in structure. It is used to irradiate the test material, by selecting certain wavelength of IF-IR.
