Long-Pass Filter Fabrication
Longpass filters are optical products with excellent filtering and high-quality fabrication. They control and adjust light wavelengths, removing unwanted wavelengths and retaining desired ones. Fabrication uses advanced, precise optical processes. High-quality quartz glass, optical glass, or other materials form the substrate. Precise cutting, grinding, and polishing produce the required shape and dimensions. Strict quality control at every stage ensures optical performance and improves service life and stability. These filters offer many advantages. They completely remove unwanted long-wavelength light to improve optical purity and quality. High transmission maintains brightness and clarity at desired wavelengths. Special surface treatment provides corrosion and scratch resistance for stable, long-term operation in harsh environments. Applications include filtering systems in microscopes, spectrometers, and laser equipment. Medical equipment, imaging systems, and communications devices use them to remove interfering wavelengths and enhance desired light. They also support research experiments, industrial inspection, and optics teaching. Overall, their strong filtering performance and quality fabrication control wavelengths to remove unwanted light and retain desired light. Across laboratory research and manufacturing, they improve optical-system performance and results.

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.
