Here's Why You Need To Measure MTF

Modulation Transfer Function or the MTF is commonly associated as a way to measure the performance of an optical system. This type of performance testing is relied upon because it can be used for the simplest optical components such as the spherical singlet lens and the most complicated systems like a telecentric imaging lens. Results from the MTF Testing are accurate and can be relied upon by establishments from all industries.

Aside from the accuracy of MTF Measurement, these are the most notable reasons why professional measuring is a must:

Reason #1: Direct Way To Measure Image Quality

Most, if not all optical system being used tend to adhere to a predetermined quality image level and integrity. Whether these systems are photographic optics or video systems, they all promise to deliver a standard level of image quality, but sadly not all can live up to the expectations. MTF can be used as a convenient measuring test of a system’s quality and performance level.

The measurements can help prevent early image degradation to help preserve all that was recorded and captured for future use without or with very minimal image quality corruption.

Test Results Are Objective And Universal

MTF testing is the perfect tool to derive an objective, truthful, and universal result. Without the external influence and potential biases of a test engineer, human judgment is no longer a factor when determining the quality and resolution of an image. The lack of biases and the objective test results are more desirable, especially when the goal is accuracy.

Ability To Recreate Exact Testing Environment

When MTF measuring is used on the wavefront or the image from an optical system, replicating the exact parameters that influence the performance and design of the lens becomes very easy. All the details needed to recreate the testing environment, no matter how small and precise, such as the field angle positions, spectral regions, and so on can be models in the MTF test.

Versatile Testing Capabilities

A standard MTF test instrument has the capability to perform a number of other tests necessary to determine the precision and quality of an image. Tests such as field curvature, level of distortion present, and even blur detection can be done via an MTF test. This versatile test allows for direct measuring of image features which helps to determine the functionality and performance of a system.

Brings Together Different Industries

This form of versatile image quality and resolution testing can benefit different sectors from industries far and wide. Designers, metrology engineers, optical fabricators, and any other field that relies on optical systems can find some use for the MTF tests to increase their efficiency and accuracy.

MTF Tests Are Necessary

Advances in technology and other related fields have increased the demand for better quality optical systems that offer higher resolution images. The results can only be replicated with the same level of accuracy by using an MTF test regularly. Professionals who rely on image accuracy and resolution for better results, it is highly recommended to get all your optical systems tested for performance quality soon.
