Composition of Different Achromatic Doublet Lenses 1. Achromatic doublet lens is a kind of common lens. It consists of several groups of positive and negative cemented lenses with different radius of curved surface. It can only correct the axial chrom...

What are the Uses of Optical Filters? Optical filters are a relatively unfamiliar concept for many people. They seem to be a little far from our daily life, but they are not. Looking closely at the surroundings, we will find that many asp...

Terms related to Optical Filters 1) Central wavelength (CWL): The wavelength used, such as the main peak of the light source is 850 nm led lamp, requires a central wavelength of 850 nm.2) Transmittance (T): Assuming that the initial ...

What are the Optical Glass Substrates for Filters? Optical glass substrates of optical filters mainly include absorption glass, such as JB510, CB535, HB850, colorless optical glass K9, float glass, B270, fused quartz, etc.Geometric dimensions and thic...

What is a Bandpass Optical Filter? In a certain band, there is only a small band with high transmittance in the middle and a high reflectivity cut-off band on both sides of the band. This kind of optical filter is collectively called b...

The Introduction of Bandpass Filter A bandpass filter is a filter that can pass the frequency component within a certain frequency range but attenuate the frequency component of the other range to a very low level. An example of analog ...

The Use of Filter in the Counterfeit Detector The currency detector is an optoelectronic instrument for checking the authenticity of banknotes, involving many fields such as machinery, electricity, light, and magnetism. The counterfeit identifica...

The Advantages and Application Range of Infrared Lens 1. Advantages of infrared lens1. The focus of infrared lens is consistent with visible light, and the image is more clear.2. The infrared lens adopts the latest optical design and special optical glas...

How Much Do You Know about the Telecentric Lens Application? 1. Application advantages of telecentric lensOne of the important advantages of telecentric lenses is that changes in object distance do not affect the magnification of the image. The telecentric lens...

Different Types of Filters Small and tiny though a filter is, it plays a vital role. As a part of the optical industry, filters play a key role. So what kinds of filters are there according to the spectral characteristics?1. Lo...

SWIR Lens 1. Introduction of SWIR lensesLight is a kind of electromagnetic wave, with the visible spectral of 0.38-0.76um, and the infrared spectral region of 0.76-1000um.The part of 0.76-3.0um is called refle...

The Application of Zoom Lenses Ⅰ. The selection principle of the zoom lensesThe maximum imaging circle size of the lens should not be less than the imaging specification of the camera chip, that is to say, 1/2 lens can be used wit...

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...

The Direction of the Filter and the Effect of Temperature on the Wavelength 1. The edge of the filter is engraved with arrows to indicate the recommended direction of the light transmission filterAlthough either side of the filter facing the light source can filter light, it ...
