Neutral Density Filter (ND Filter) ND70
The medium density filter (Neutral Density Filter) is widely used in imaging and laser systems and is effective in reducing light intensity and preventing damage to camera sensors, photometers or other precision optical components, thereby ensuring the accuracy of measurements and equipment security. The filters achieve a flat reduction in the spectrum of selected bands by absorbing or reflecting partial light, so that they control light power precisely; and maintain stable pass rates within 400-700 nm visible light, without change with wavelength, ensuring colour consistency, especially for applications that require strict optical precision and colour requirements.

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.
