What Are the Differences Between High Precision Grinding Spherical Lens and Aspherical Lens 1. Spherical lens and aspherical lensLenses have different shapes and different parameter requirements. Nowadays, spherical lenses and aspherical lenses are often seen. Let’s take a look at the diffe...

The Basics of Bandpass Filters Bandpass filters are used to transmit the required wavelength range and cut off the unwanted wavelength range. Their design is essentially a thin film formed by vacuum deposition technology, which con...

Basic Concepts and Parameters of Optical Filters 1. The basic concept of optical filterAn optical filter is simply an optical device used to selectively filter the required radiation band. The substrates are mostly optical materials such as white gl...

Classifications of Filters Although there are many types of filters, they all have the same basic function: transmit light of a specific wavelength or color range while preventing the remaining wavelengths from passing through....

How to Judge the Quality of Optical Lenses? Ⅰ. There is no good or bad optical lensesTheoretically speaking, the optical lenses can only be suitable or not. Generally, the more expensive the optical lenses, the better the image quality. The op...

How to Choose a Laser Lens? 1. Choose a laser lens with excellent technologyAs the foundation and important part of the optoelectronic technology industry, laser lenses need to provide a good guarantee for technology, especially...

Basic Knowledge About SWIR Lensens 1. SWIR Lenses is also an optical lensSWIR Lenses refers to the wavelength range between 900nm and 2500nm, which is invisible to the naked eye.Light is an electromagnetic wave. SWIR lenses is located...

Tips on Selecting The Bandpass Filter 1. What is Bandpass Filter?Bandpass Filter is optical filter that passes one or more specified wavelength bands while blocking other wavelength bands. Bandpass Filter refers to wavelength ranges and i...

What is the Difference Between Spherical and Aspheric Lenses? 1. The difference between spherical and aspheric lenses: surface curvatureThe difference between spherical and aspheric lenses: a spherical lens refers to a constant curvature from the center to the e...

The Benefits of Zoom Lenses and the Precautions when Using Them 1. The benefits of zoom lensThe biggest advantage of a zoom lens is: convenience. You don't have to bring a lot of lenses on business trips, making it easier. The zoom lens is relative to the fixe...

What Are the Significant Performance Characteristics of Achromatic Lens? Ⅰ. Anatomy of achromatic lensAn achromatic lens, also called achromatic, is usually composed of two optical elements joined together. These two optical elements are usually a positive low index (crow...

Why Use an Anamorphic Lens? How to Use It? If you like to shoot videos, you must have heard of anamorphic lenses, and even considered buying anamorphic lenses. What exactly is an anamorphic lens? Is the video shot with it really similar to the...

How to Maintain Projection Lenses? Ⅰ. The projection lenses need cleaning and maintenanceSince the projection lens is directly exposed to the air, dust will inevitably fall on the surface of the lens. If the dust on the lens is not re...

What Are the Applications of Sapphire Lenses in Infrared Transparent Windows？ Ⅰ. Sapphire lenses are excellent optical lensesAs an excellent optical lens, the sapphire lens has good transmittance in the ultraviolet, infrared, and visible light bands, which can meet the require...

Use Anamorphic Lenses in the Digital Age An anamorphic lens is a special tool that affects how the image is projected onto the camera sensor. They were originally created to allow a wider aspect ratio to be adapted to standard film images, b...
