1550nm SMA collimator NA 0.2 focal length 11mm

Idealphotonics' fiber collimators are pre-aligned to collimate light from FC/APC-connected fibers and have diffraction-limited performance. These fiber collimators have no moving parts, are compact, and can be easily integrated into existing devices. Because aspheric lenses produce chromatic aberration, the effective focal length (EFL) is wavelength-dependent. The design wavelength is the wavelength corresponding to the ideal beam divergence. Some collimators at the design wavelength have different collimated beam diameters. When connected to specific single-mode fiber patch cords, they can collimate light at the design wavelength. In addition, the aspheric lenses are anti-reflection coated on both sides to minimize surface reflections (see the AR Coating Curves tab). For some applications, the collimators can also be used for other wavelengths within the AR coating wavelength range. Please refer to the theoretical divergence angle curves for each collimator to determine whether it is suitable for your application. These collimators have a stable operating range from -40°C to 93°C. Please note that these collimators cannot be used in a vacuum. For custom alignment wavelength, operating temperature or vacuum compatibility, please contact us for customization.
