Zoom fiber collimators can change beam size continuously while keeping beam pattern homogeneous and clear. It works like zoom lenses of camera, instead of only adjusting separation distance between lenses and fiber as focus adjustable fiber collimators. Beam quality is much better than focus adjusting. It can be used in telemetry, illumination, lidar and so on.
-
Ultra long work distance fiber collimators have over 2km work distance by expanding laser beam from fiber to dozens of millimeters, even over 100mm beam diameter. It's used in telemetry, illumination, lidar and so on, which project laser to remote distance. Multi-groups air-spaced lenses are used to optimize the power distribution. The beam spot is homogeneous and has clear board line.

Single mode pigtailed fiber collimators are used to transform the laser emitted from fiber into a parallel Gaussian beam by finely positioning the lens to fiber or couple the parallel Gaussian beam into fiber in inverse. It can be used in reflective type and thrubeam type. Normally, a sphere lens or GRIN lens is used in collimator to transform light. It can be divided into specified working distance collimators and wide working distance range collimators.

Single Mode Achromatic Fiber Collimators is used for wide band application. Chromatic aberration is elaborately compensated with special design on materials, curves, thickness and separation of lenses. Please use right connectors and fibers listed in tables.

At Z-Optics, our SHORTPASS FILTERS are precision-engineered optical filters designed to transmit wavelengths shorter than a specified cut-off point while effectively blocking longer wavelengths. These filters provide excellent optical density (OD) and broad operational wavelength ranges, making them indispensable components in diverse optical and photonics systems requiring sharp spectral cutoff.

Short Work Distance Pigtailed Fiber Collimators can focus light into a very small spot(several microns to dozens of microns diameter), which is important for some applications like topography, ranging.

Reflective Achromatic Fiber Collimators uses a 90⁰ off-axis ellipsoidal mirror to couple free space laser beam into fiber or vice versa. Focal length of reflective mirror is irrelevant with wavelength. That makes it an idea solution to achromatic aberration. Al, Ag and Au is optional to be deposited as reflective film.
- Aluminum averages greater than 90% reflectance from 200nm to the far infrared, except in the 750 – 900nm region where it averages around 85% reflectance.
- Silver coatings can offer better performance in the visible and NIR from 450nm to 2μm.
- For IR performance gold coatings offer high reflectivity of around 97% from 700nm up to 10μm.
