  • Image encryption using spatial nonlinear optics

    Optical technologies have been widely used in information security owing to its parallel and high-speed processing capability. However, the most critical problem with current optical encryption techniques is that the cyphertext is linearly related with the plaintext, leading to the possibility th...

  • Refraction of light

    Refraction of light

    When light obliquely enters another medium from one medium, the propagation direction changes, so that the light deflects at the junction of different media. Characteristics: like light reflection, light refraction occurs at the junction of two media, but the reflected light returns to the origin...

  • Miniscope Opens a Window Into the Brain

    Scientists use calcium imaging to study brain activity because activated neurons take in calcium ions. Researchers in Norway designed and demonstrated a small two-photon microscope (MINI2P) for large-scale calcium imaging of brain activity in freely moving mice (Cell, doi: 10.1016/j.cell.2022.02....

  • Fused quartz windows

    Fused quartz windows

    Fused quartz windows have excellent optical quality, low coefficient of thermal expansion, and transmission over 80% at a wavelength range of 260nm to 2500nm. Fused quartz is harder than glass and can be used at temperatures up to 1050°C. Fused quartz windows are widely used in scientific researc...

    Science:Time-of-flight 3D imaging through multimode optical fibers

    At present, a number of research teams, such as the University of Glasgow in Britain and the University of Exeter in Britain, have jointly achieved the goal of capturing 3D images of objects within tens of millimeters to several meters from the tip of the optical fiber at a video frame rate of 5h...

  • What’s optical filter?

    There are three types of optical filters: shortpass filters, longpass filters, and bandpass filters. A shortpass filter allows shorter wavelengths than the cut-off wavelength to pass through, while it attenuates longer wavelengths. Conversely, a longp...

  • Advantages of Calcium Fluoride – CaF2 lenses and windows

    Calcium Fluoride (CaF2) can be used for optical windows, lenses, prisms and blanks in the Ultraviolet to Infrared region. It is a relatively hard material, being twice as hard as Barium Fluoride.  Calcium Fluoride material for Infra-red use is grown using naturally mined...
