780nm FC/APC Fixed Fiber Collimator NA 0.37 Focal Length 10.1mm

Idealphotonics' fiber collimators are pre-aligned to collimate light from FC/APC connector 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 angle. Some collimators at the design wavelength have different collimated beam diameters. When connected to specific single-mode fiber jumpers, 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 of 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. If you need a custom alignment wavelength, operating temperature, or vacuum compatibility, please contact us for customization.
