  • 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...

  • Optical glass prism

    Optical glass prism

    Light enters from one side of the prism and exits from the other side. The outgoing light will deflect to the bottom (the third side). The deflection angle is related to the refractive index, vertex angle and incident angle of the prism White light is polychromatic light composed of all kinds of ...

  • 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...

  • 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...

  • Optical glass polishing technology

    Optical glass is finely ground by the grinding liquid,  optical glass surface has a crack layer for 2–3 m thickness, so the method of eliminating the crack layer is for polishing. The mechanisms of grinding and polishing are the same, except for the t...
