Thorlabs' new KT120(/M) fiber launch system couples free-space laser beams into fiber optic cables. This system, which can be used with single or multimode fiber, is equipped with high-precision differential adjusters capable of submicron translation.
This fiber launch system only includes optomechanical components. Recommended optics for focusing collimated light into an output fiber connected to the KT120(/M) system are offered separately. Note that to reach the best coupling performance into a multimode fiber, the numerical aperature of the lens should match that of the fiber. Similarly, for optimized coupling into a single mode fiber the spot size of the focused beam must be less than the mode-field diameter of the fiber.
Includes:
- KT120(/M) Fiber Coupler Accepts FC or SMA Fiber Cables
- High-Precision Differential Adjusters Included with KT120(/M) Provide Submicron Translation
- KT311(/M) Spatial Filter Directly Compatible with Ø9 mm Aspheric Lens Housings
- Easy-to-Follow Instructions and Alignment Tools
Spatial Filter Systems
Many applications, such as holography, require a beam with uniform intensity. The new KT311(/M) spatial filter is ideal for producing a clean, spatially uniform, Gaussian beam. The input of this system consists of a Z-axis translator, which can house a diffraction-limted aspheric lens. This aspheric lens focuses the beam through a pinhole, which can be mounted in the XY translator. The output consists of a Ø1" cage mount, which holds and centers a collimating optic.
This filter system only includes optomechanical components. The aspheric lens, collimating optics, and pinhole must be purchased separately.
