  • USES OF OPTICAL GLASS PRISMS

    Optical prisms can be used for a variety of purposes, depending on the specific properties of the prism and how it is designed. Some of the most common uses of prisms include: Dispersion :Prisms can be used to separate white light into its individual colors, a process known as dispersion. This is...

  • What are the characteristics of optical quartz glass (JGS series )?

    1. High temperature resistance. The softening point temperature of quartz (JGS series glass) glass is about 1730 ℃, which can be used for a long time at 1100 ℃, and the maximum use temperature in a short time can reach 1450 ℃. 2. Corrosion resistance. In addition to hydrofluoric acid, quartz (...

  • 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...

  • 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...
