Regardless if you are an optical designer or not, when you wanted to compare the different optical systems based on their performances, you will usually use the modulation transfer function for your measurement. Therefore, you will need to choose an MTF Testing Company, but before that, it is important that you educate yourself first about everything you need to know when it comes to modulation transfer function.

Modulation transfer functions are utilized for those components such as a spherical singlet lens even the most complex multi-element such as the telecentric imaging lens. The ability of the imaging system in determining the details in an object is called the resolution. It is usually expressed in line-pairs per millimeter that you can also call as the frequency. If you wanted to have a more detailed and specific explanation of your target tests, you should consider several factors when it comes to choosing the correct test target. To put it simply, images with high resolution are more detailed because it has a less amount of blurring while those images with the poor quality of resolution lack most of the details that often results in blurred pictures.

Now that you know what a resolution is to let us consider the modulation transfer function. The MTF of a certain lens it its ability to measure and transfer the contrast at a specific resolution that is the object going to the image. In short, the modulation transfer function is considered as one of the ways in incorporating the resolution of an image and contrasting it into a single specification. However, as the line is decreasing on your test target, then you can conclude that it will be difficult for the lens in transferring the lowered contrast and the modulation transfer function decreases as well.

Modulation transfer function is considered as one of the most effective tools when it comes to quantifying the performance of an image in a system when it comes to the contrast and the resolution. Being able to learn the curves of the modulation transfer function in each and every imaging lenses camera sensor will make it easier for the optical designer to choose the most appropriate selection when he opts to optimize a certain resolution.

Also, when it comes to analyzing the system MTF, it can be easier to choose the combination that will eventually come into fruition of a successful performance. For instance, there are some applications in metrology where of contrast is strictly required to have an accurate image edge detection. That’s how importance modulation transfer function testing is. Therefore you need to choose the company that could provide high-quality equipment and tools that will help you in performing well. In choosing the imaging company that you wanted to hire, there are several factors that you need to consider in order to make sure that you can execute your job and complete your task using the fine measuring equipment.
