515nm Notch Filter
The 515 nm notch filter is a band rejection optical thin film component. It provides high reflection or absorption only within a very narrow band near 515 nm, typically with a full width at half maximum of 15-20 nm, while maintaining transmittance of at least 90% across the remaining visible to near infrared region. It rejects interference near 515 nm, such as the 514 nm argon ion laser line, green LED peaks and fluorescence excitation lines, while allowing other wavelengths to pass with almost no loss. Its function is the opposite of a bandpass filter.

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.
