Lithographically Patterned Multispectral Filter
Lithographically patterned multispectral filters are precisely fabricated using combined lithography and coating processes, integrating multiple spectral channels at different positions on one substrate. Each channel offers excellent spectral characteristics and very high spatial alignment accuracy.

Optical-glass neutral-density filter Optical Filters Uni-lens
Dimensional Tolerance: ±0.5 mm Surface Quality: 80-50 or higher Surface Figure: 4~6λ or better
Neutral-density filters make photographic exposure easy to control. By blocking light from reaching the camera sensor, they allow the camera to maintain a larger aperture for longer.

Machine-vision bandpass filter Optical Filters Uni-lens
Coating: Antireflection coating Surface Quality: 40/20 Guaranteed peak transmission: >90%
A bandpass filter passes frequencies within a specified range and rejects or attenuates frequencies outside it, selectively transmitting part of the spectrum while rejecting all other wavelengths.
-
Longpass filter Optical Filters Uni-lens
Filter Type [LP Series]: Optical interference or colored-glass filter
Long-pass filters serve gas monitoring, temperature sensing, other sensing, thermal imaging, and motion detection. They block shorter wavelengths and transmit longer wavelengths. Blocking can result from reflection, absorption, or both. An antireflection coating on the second surface can improve passband transmission.

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.
