The concept of narrowband filter A narrowband filter is a type of electronic device that allows a specific range of frequencies to pass, and of course blocks frequencies that are not within the range. This is what we call a “passband,” and frequencies outside this range will be blocked. Attenuation or blocking. Narrowband filters help …
In the field of optics, lenses play an important role in shaping our visual perception and interactive experience of the world around us. Among them, achromatic lenses, as a key technology with a long history, have successfully solved the chromatic aberration problem in optical imaging, which is manifested as obvious color fringing at the …

Introduction to optical prisms Optical prisms are transparent solids with flat surfaces that refract light. They play a crucial role in manipulating light, causing it to change direction, split into different wavelengths, or merge multiple beams. The surfaces of optical prisms are meticulously polished to ensure high clarity and precision. The angles between the …
The concept of spherical lenses The optical element we use most often is the spherical lens, whether used alone or in combination. These are our most commonly used components. Definition of spherical lens and cylindrical lens If we cut a sphere made of glass, then our terminal is a spherical lens, with flat and …
Introduction to optical filters Filters selectively transmit parts of the spectrum while rejecting other parts. Edmund Optics’ optical filters are widely used in microscopy, spectroscopy, chemical analysis and machine vision and are available in a variety of filter types and accuracy levels. This application note details the different techniques used to create EO filters, …
What is The Meaning of Optical Scanners? Optical scanners are input devices that convert digital signals using images, text, codes, or objects into two-dimensional (2D) digital files, and then send this information to computers and fax machines. Among them, the most popular optical scanner device is the flatbed scanning device. Optical scanners can be …
What does a prism look like? A prism is a three-dimensional shape in our daily life. A prism has two types of faces. The prism is named according to the shape of its base. The faces of a prism other than the top and bottom are called the sides of the prism. All sides …
What is a microscope? In our understanding, microscopes allow us to peek into the world that cannot be seen clearly with the naked eye. Telescopes can take us to understand the earth’s world and detect stars and planets in the night sky. The light beams from lighthouses can be projected to very far away places. …
The term “optical components” refers to a range of parts and products used to build optical systems. These components include precision optical components such as spherical, aspheric and cylindrical lenses, mirrors, prisms, filters, and mechanical mounts that help guide or focus the beam. Designing and manufacturing optical components is a complex task. Our factory …
Diode lasers, also known as semiconductor lasers, operate by passing an electric current through a semiconductor material. This process generates light, which is then amplified to produce a coherent laser beam. The specific wavelength of the laser depends on the band gap of the semiconductor material used. In diode lasers, electrons and holes (positive …
