Title:
OPTICAL FIBER COLLIMATOR FOR OCT, MANUFACTURING METHOD, AND OCT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/227144
Kind Code:
A1
Abstract:
An optical fiber collimator for OCT, a manufacturing method, and an OCT device. The optical fiber collimator comprises an optical fiber (10) used for transmitting a light beam, and further comprises an optical lens (20) used for collimating the light beam; one end of the optical lens (20) is connected to one end of the optical fiber (10) by means of fusion splicing, so that a fusion splicing portion (30) is formed between the optical lens (20) and the optical fiber (10); the other end of the optical lens (20) is provided with an inclined surface (21); a light reflecting structure (40) is provided on the inclined surface (21); the side surface of the optical lens (20) adjacent to the inclined surface (21) forms a light incident/emergent surface (22). The optical fiber collimator for OCT, the manufacturing method, and the OCT device have the characteristics of short overall size, simple assembly process, and less contamination to the optical path.
