Window sheet refers to a thin, transparent material made of single or multiple layers of fluoride, quartz, and other materials. Used in vacuum systems, optical instruments, electronic equipment, and other fields. So what are the applications of window slices?
Scratches on optical window sheets do have a certain impact on their performance and use, depending on the location, length, quantity, and distribution of the scratches.
1、 Location of scratches
If scratches appear around the lens or near the optical center but deviate from the main light path, their impact on imaging quality may be relatively small. If the scratch happens to be located at the optical center or main light path, it will have a significant impact on the imaging quality.
2、 The length of the scratch
The length of scratches can be divided into long scratches (greater than 2mm) and short scratches (less than 2mm). Long scratches are more likely to have a significant impact on imaging quality compared to short scratches.
3、 The number and distribution of scratches
The impact of individual or few scratches may be relatively small, but if there are numerous and uniformly dense scratches, especially in the optical center area, they will seriously affect the performance of the optical window. If there are numerous and evenly distributed small scratches, it can cause changes in refractive index, decreased transmittance, loss of membrane function, and result in poor visual correction, unclear vision, and a foggy appearance.
4、 The impact on optical performance
Scratches on optical window sheets can cause scattering, refraction, and absorption of light, thereby affecting the imaging quality and resolution of optical instruments. Scratches may also interfere with the reception and signal detection of external light sources by optical instruments, affecting the accuracy of measurement, monitoring, and control.
The above is the answer to whether scratches on optical window sheets are affected. We hope it is helpful to you. If you have any questions, please feel free to consult or leave a message online.
