Colored Bandpass Filters DTB530
Bandpass filter glass, abbreviated as bandpass glass, has a relatively narrow passband with short- and long-wavelength cutoffs, as shown in the figure. Its spectral properties are described by transmittance (TM), its wavelength position (λM), short- and long-wavelength cutoffs, and half-width. The difference (λ1-λ1)nm between wavelengths λ1 and λ2 at half the bandpass-glass transmittance is called the half-width. The short-wavelength cutoff is the wavelength on the short-wavelength side of the peak where transmittance is zero. The long-wavelength cutoff is the wavelength on the long-wavelength side where transmittance is zero. For some types, transmittance does not reach zero on the long-wavelength side, so transmittance at a specified wavelength is used. Bandpass glass is named DTB from Chinese pinyin initials, with the wavelength position of its transmittance value used as the identifying number.

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.
