Applications

Applications include coupling optimization when source wavelength or mode changes, coupling fibers with different numerical apertures, and high-power laser coupling. Recoupling after beam-size changes: when the collimated source spot does not match the fiber receiving surface, focusing through the objective can reoptimize coupling conditions. Coupling fibers with different core diameters: for different cores, such as 9µm single-mode and 1000µm multimode fibers, the objective can be replaced or its focus adjusted for optimal coupling efficiency. Fiber coupling in free-space optical paths: efficiently couples light into fiber after free-space components such as lasers, modulators and attenuators. Optical signal input in microscopy: couples signal light from microscope optical paths into fiber spectrometers or detectors. Teaching and experimental verification: its clear structure and full adjustment dimensions suit course experiments in fiber optics and laser technology.

Key Features

Collimator adjustment: ±4° pitch adjustment and ±3mm translation to optimize incident beam pointing. Focus adjustment: ±2.5mm along the objective XY axes, with 12mm Z-axis travel and 10μm graduations to control focal position. Standard fixed-focus collimator: integrated, with selectable wavelengths of 405-850nm. The collimator interface supports FC/PC2.2, FC/APC2.2 or SMA, with one of the three selected when ordering; a fiber adapter plate for the selected interface is included. The system optical axis height is fixed at 84.1mm.
