Cleaning Treatment Method Of Optical Filter Commonly used optical filter cleaning methods are:Ⅰ. Solvent cleaning of optical filtersCommonly used solvents are aqueous solutions (acid or alkali solutions, detergent aqueous solutions, etc.); anh...
Inspection Of Surface Cleanliness Of Optical Filters Before cleaning the surface of the optical filter, the cleanliness of the glass surface must be checked, and the cleaning method should be selected based on this. Commonly used inspection methods are:...
Main Factors Affecting The Performance Of Narrow Band Optical Filter Ⅰ. Reasons affecting the performance of narrow band optical filterThere are a certain number of pores in the film. Before the film is not absorbent, the pores in the film are filled by air and the re...
LASER-World of Photonics, Germany The World's leading trade fair for components, systems and applications of photonic successfully held in Munich, Germany, in April 2022. ECOPTIK participated in this event as an exhibitor.First of...
Introduction To Narrow Band Optical Filters 1. What is a narrow band optical filter?The so-called narrow band optical filter is subdivided from the bandpass filter. Its definition is the same as that of bandpass filter: this filter allows light...
What Is The Plano Convex Lens? 1. What is the plano convex lens?The plano convex lens is a positive lens in the optical system, whose main functions are beam expansion, imaging, beam collimation, focus collimation, the collimation ...
What Is The Plano Concave Lens? 1. What is the plane concave lens?Plane concave lens is a negative lens with a negative focal length, and the parallel light beam will diverge after incident on the plane concave lens. The outgoing li...
Laser World of Photonics 2022 in Munich, Germany Dear Sirs,We cordially invite you to visit us at Laser World of Photonics 2022 in Munich, Germany, from April 26 - 29, 2022. ECOPTIK is presenting lenses, spherical lenses, laser windows, filters etc....
Importance Of Using Cylindrical Optical Lenses Two orthogonal directions of a cylindrical optical lens define the reference system: the power direction and the non-power direction. The first direction is called the "refractive direction"...
What Makes Achromatic Cylindrical Lenses Important? Because achromatic cylindrical lenses focus colors at the same point, they enable users to focus on an image completely. Achromatic cylindrical lenses produce clearer images than uncorrected singlet l...
Classification and Characteristics of Right Angle Prism Ⅰ. UV fused quartz right angle prismIf the uncoated needs higher UV transmittance or lower thermal expansion coefficient, you can choose UV fused quartz right angle prism. UV-grade fused quartz has h...
Analysis of Main Causes of Center Wavelength Shift of Optical Filter Film In the production and application of the filter, it is often encountered that test data of filter product coating is not the same as the measured spectrogram after a few days and the wavelength of the...
What are Optical Lenses? Ⅰ. About optical lensesOptical lenses are lenses manufactured by optics. One of typical lenses are cylindrical optical lenses. Optical lenses have specific optical properties such as refractive index...
The Function of Optical Mirror and the Rule of Imaging Ⅰ. The role of optical mirrorAn optical lens is a visual element made of transparent materials (such as glass, crystal, etc.), which will affect the curvature of the wavefront of light. It is a devic...
The Principle and Application of Optical Filter Film The filter is made of plastic or glass and special dyes. The red filter can only let red light pass through, and so on. The refractive index of the glass sheet is initially similar to that of air, and...
