What is a Bandpass Optical Filters

At present, Bandpass Optical Filters are widely used as optical components for filtering and selecting spectral lines.


Three methods of surface cleaning for Bandpass Optical Filters products

With the rapid development of high technology, Bandpass Optical Filters products have become common in our lives, but many people do not understand how to deal with dirty lenses. Today we will talk about the cleaning process of the surface of Bandpass Optical Filters products.


Application of Bandpass Optical Filters

A Bandpass Optical Filters is a filter with a cutoff band on both sides of the transmission band of the spectral characteristic curve. Bandpass Optical Filters transmit only certain wavelength bands and block others. The width of this filter is expressed in the range of wavelengths it allows to pass, which can range from a few nanometers to hundreds of nanometers.


How to clean the dirty surface of Bandpass Optical Filters products

With the rapid development of high technology, Bandpass Optical Filters products have become common in our lives, but many people do not understand how to deal with dirty lenses.


How to increase the life of optical glass sheets

Keeping the optical glass sheet often clean will increase the life of the optical glass sheet. Because pollution will cause many problems with the lens, the uneven distribution of laser power during reflection makes the lens base temperature high and the marginal temperature low. This change is called the lens effect in the optics.


How to understand the bandwidth of the Bandpass Optical Filters

The two wavelengths in a Bandpass Optical Filters whose transmittance is equal to 50% of the peak transmittance are called half-power wavelengths.


What are the factors that affect the price of Bandpass Optical Filters products

The first is the cut-off depth of Bandpass Optical Filters products. The better the cut-off depth is, the influence of clutter on the sensing components can be shielded, which will allow the optical sensing components to respond to more accurate signals.


An indispensable component in the optical glass vision system

Optical glass can change the direction of light transmission, and can change the relative spectral dispersion of ultraviolet, visible or infrared light. Optical glass has stable optical properties and high optical uniformity. Optical glass has the advantages of high temperature resistance, low expansion coefficient, high mechanical strength, and good chemical properties. It is used to make prisms, lenses, Window and mirror, etc.
