400~1650nm Achromatic Fiber Collimator
The achromatic fiber collimator features adjustable effective focal lengths (EFL) of 20mm, 40mm, and 80mm. Each collimator is equipped with one of three connector types: FC/PC, FC/APC, or SMA905. It is compatible with non-telecentric systems and can be used for long-distance collimation or coupling light into free space. The red alignment ring allows for precise adjustment between infinite and near focus distances.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
In photonics and laser technology, devices that manipulate optical signals via the electro-optic effect form the backbone of precision optical systems. Electro-optic phase modulators and electro-optic deflectors are two prominent examples of this device category. As a critical hardware solution for high-speed, high-accuracy laser beam direction control, electro-optic deflectors are widely deployed across industrial and research settings. Below is a detailed overview of their core structure, key performance drivers, and primary use cases.
