L-Quad Enhance Filter
The L-Quad Enhance Filter is a four-bandpass light-pollution suppression filter for color cameras. It effectively suppresses transmission at light-pollution wavelengths, especially artificial illumination including mercury and high- and low-pressure sodium lamps, and reduces the impact of natural skyglow. It improves contrast and detail in astronomical images, making targets more distinct and dimensional. It strengthens light-pollution suppression while maintaining color balance, supporting both star fields such as the summer and winter Milky Way and deep-sky objects such as nebulae, galaxies, and star clusters. It saves substantial imaging time while improving results. The four-bandpass design maximizes color balance for broadband celestial targets such as nebulae and galaxies.

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.
