    • What is the Tyndall Effect?

      What is the Tyndall Effect?

      The Tyndall Effect refers to the reflection of light as it comes in contact with small particles in a translucent medium. It involves the scattering of light in different colors depending on how short or long a particular wavelength is. For example, the Tyndall Effect can describe the haze seen as light travels through a

    • What is a Diopter?

      What is a Diopter?

      A diopter is a lens that bends light in order to magnify an object. Diopters can be used to enlarge small objects or see across far distances and are generally integrated into other objects in order to maximize efficiency and accessibility. A diopter can also refer to a measurement that describes a lens’s optical power

    • How a Laser Cutter Works

      How a Laser Cutter Works

      A Laser cutter is a machine that uses a laser to cut materials. The Laser Cutter works by making the laser enter through the side of the material that needs to be cut and shoots it through the axis of the beam. If a cut needs to be made and there are no edges near

    • What is a Refractometer?

      What is a Refractometer?

      Refractometers measure the refractive index of liquids, gases, and translucent solids such as gemstones. The measurement of how much the speed of light is reduced when traveling through a gas, solid, or solution is referred to as the refractive index. When the device is used to test liquids, it typically measures the salinity, fluid concentration,

    • PIR Sensor

      PIR Sensor

      A PIR (Passive Infrared) sensor detects infrared light that is emitted from objects within its field of view. PIR sensors differ from other infrared sensors because they can only receive infrared waves. Because all objects emit infrared waves (electromagnetic waves that travel with heat), PIR sensors can detect objects that are in front of them.

    • How a Laser Printer Works

      How a Laser Printer Works

      A laser printer unlike an inkjet printer uses a laser light beam for printing operations. It is also distinct from other printers because of its exceptional printing speed as well as highly accurate rendering. It utilizes a xerographic (a process of creating an image by the action of light on a specifically coated charged plate)

    • Parabolic Mirror

      Parabolic Mirror

      Parabolic mirrors are specially shaped in order to capture and focus energy onto a single point. They also distribute energy from a single point outwards. The mirrors are a specific paraboloid type that is rotated around its axis, and is also known as a circular paraboloid. Parabolic mirrors are also referred to as parabolic reflectors

    • What is Electroluminescence?

      What is Electroluminescence?

      Electroluminescence is the phenomenon where a material emits light when electricity is passed through it. It is one of the greatest discoveries of the twentieth century and other forms of luminescence, including incandescence, chemiluminescence, cathodoluminescence, triboluminescence, and photoluminescence rival it. Electroluminescence generally involves a material producing light without producing heat. It is different from black

    • Laser Distance Measurement

      Laser Distance Measurement

      For the past two decades, lasers have been used to measure distance without having to physically touch the area or things being measured. Laser measurement is capable of very precise and quick distance measurements. Lasers have been used in military targeting, criminal investigations, and sports. As research has progressed, the size of laser measuring devices

    • What Are Photonic Crystals?

      What Are Photonic Crystals?

      Photonic crystals are those that manipulate how photons are absorbed or reflected off of them. They occur in nature and are made of dielectric nanostructures that allow certain wavelengths to pass through them while blocking other wavelengths. The visible light portion of the electromagnetic spectrum’s wavelengths is responsible for colors, therefore photonic crystals can spontaneously
