Compared with the film age, photographers in the digital age need a lot fewer filters, but there are still some optical filters that are still necessary. Part of it is because it takes time and effort...

Ⅰ. What are optical filters?The color filter is a colored transparent sheet that absorbs, reflects and transmits colored light. The optical filter is made of colored optical glass material, which has...

What is a spherical lens? What is an aspheric lens? What is the difference between the two? Why are aspheric lenses recommended? Let's talk about the difference between the two.The spherical lense...

Aspheric lenses can improve image quality and correct imaging problems usually associated with spherical lenses. The original work and function of the aspheric lens are mainly reflected in the followi...

1. Introduction to penta prismThe penta prism uses the reflection of the two surfaces to deflect the beam by 90° while maintaining the parity of the image. The deviation of the beam does not change t...

1. Introduction to optical prismsIn optical devices, optical prism is a piece of glass or other transparent material cut at a precise angle and plane, which can be used to analyze and reflect light.Or...

Ⅰ. Introduction of optical filtersThe optical filter is made of plastic or glass, added with special dyes. The red filter can only pass the red light and so on. The transmittance of the glass sheet i...
