What are the types and differences of filters?

Each product developed has the characteristics of each product. There are different types of filters, and the characteristics of different types of products are different. In the process of product classification, if the classification filter is classified according to the purpose of use, it can generally be divided into TLRF filter, interference filter, all-class reflection filter and AN filter, Raman filter, FLSH fluorescence filter and plain hybrid filter.

According to the different functions of the filter itself, it can be divided into excitation filter, filter binomial, binomial filter, notch filter, fuel filter, fluorescein filter, ND filter, neutral filter, neutral gray mirror, cut-off filter, high-pass filter, low-pass filter, band-pass filter and uv filter.

The filter is divided into different varieties and has different characteristics. In the market, the filters that are widely used are fluorescent filters, medium-gray mirror filters and fluorescent in situ hybridization filters. There are relatively many applications. What are the characteristics of the filter when it is used?

For example, fluorescent filters are mainly used in the fields of life science and biomedicine. The most important role is to separate and select the characteristic band spectrum of the excitation light and emission fluorescence of the material in the biomedical fluorescence detection and analysis system, so as to understand the effect of the later use of this kind of biomedical material, which is very helpful for the medical industry and has relatively high requirements for the quality of the filter.

Neutral gray mirror filter is also called medium gray density mirror. The function is to filter the light evenly. This function is non-selective. That is to say, the reduction ability of the n d mirror to different wavelengths of light is the same. The uniform effect will not have any impact on the color of the original object, and it can be a real scene in real life.

The main function of fluorescence in situ hybridization filter is to hybridize with DNA molecules in the environmental genome to detect the presence and demeanour of the specific microorganism population based on the fluorescent labeled specific oligonucleotide chip as a probe. It is widely used in experiments. After understanding the characteristics of different filters, enterprises only know how to determine the product type when purchasing products. It can help enterprises choose the product types to purchase more accurately when purchasing products.
