Title:
OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2024/031998
Kind Code:
A1
Abstract:
An optical module. The optical module comprises a circuit board (300), a light emitting component (500), a first light receiving component (600), a second light receiving component (700), and a rounded square tube body (400), wherein the light emitting component (500) comprises a laser chip (544) and a first lens (543); the light emitting component (500) is configured to emit a first wavelength emitting light; the first light receiving component (600) is configured to receive a first wavelength reflected light, the first wavelength reflected light being light reflected back from the first wavelength emitting light by the outside of the optical module; the second light receiving component (700) is configured to receive a second wavelength receiving light; each of the light emitting component (500), the first light receiving component (600) and the second light receiving component (700) is connected to the rounded square tube body (400); and an optical assembly is provided inside the rounded square tube body (400), and comprises a beam splitter (820), a light absorber (830), a reflector (870), a first filter (850), a second filter (860), a third filter (880), and a second lens (890). A dual-lens system is formed by the first lens (543) and the second lens (890), so that the optical coupling efficiency is improved; and one emitting and two receiving functions of the optical module are realized by means of the optical assembly.
