Optical Fiber Collimator, F=11.00mm, 405nm FCAPC Mount, United Optical Technology Co., Ltd (CAT#: STEM-OP-1551-YJL)

Optical Fiber Collimator, F=11.00mm, 405nm FCAPC Mount, model 140543, is manufactured by United Optical Technology Co., Ltd.
Fiber Optic Collimators effectively combine high-performance molded glass aspherical lenses and easy-to-connect optical fiber connectors. The assembly has an external thread for quick attachment to an optical bench or instrument.
Our fiber optic collimators are fixed focal length, factory aligned, and can be used with single-mode fiber patch cords to collimate the output light of FC/PC, FC/APC or SMA connector fibers. Both sides of the aspheric lens are coated with anti-reflection coating, which can effectively reduce surface reflection and provide diffraction-limited performance in the wavelength range of 543nm to 1550nm.

Lens FL: 11.00mm
NA: 0.25
Debug Wavelength: 405nm
Full-width Divergence: 0.30mrad
Waist Radius: 1.72mm
Dimensions: M11X0.5-6g
Mount: FCAPC
MOQ: Inquire

For some applications, collimators can also be used for other wavelengths within the AR coating wavelength range. However, due to the chromatic aberration of aspheric lenses, the effective focal length changes with wavelength, so they can only achieve ideal collimation effects at the design wavelength.
