Patent ID: 6978065

Claim:
An optical fiber collimator, comprising: a housing having a first channel and a second channel, said first channel being coupled to said second channel; an optical fiber having an optical fiber termination, a portion of said optical fiber being in said first channel and said optical fiber termination being in said housing; and a collimating lens system disposed in said second channel being optically coupled to said optical fiber through said optical fiber termination; wherein, said housing, comprising: an outer tube; and an inner tube disposed at least partially in said outer tube, the channel in said inner tube being said first channel, and said inner tube is made substantially from an optical fiber compatible material selected from the group consisting of ruby, quartz, and sapphire; said housing is a multi-piece housing; and said housing allows an adjustment of a relative offset between the optical axis of said collimating lens and an optical axis of said optical fiber at said optical fiber termination.
