MTF testing is the measurement of the ability of optical systems to transfer various levels of detail from an object to an image. Performance is measured in terms of contrast (the intensity difference between the image’s black and white regions) and accounts for real-world factors like optical blurring.

In the past, when sensors only offered at most 640 pixels, it was easy to make an imaging lens that could outperform the camera’s sensor. Today, with pixel sizes less than 1 micron,  pixel count on sensors have significantly increased —sensors now regularly have over six million pixels. To keep up with this technological advancement and provide superior image quality, lens performance must increase, and measuring how well a lens performs requires the correct metrology. This is where resolution and modulation transfer function (MTF) testing comes in.

Polarized sunglasses lenses cut surface glare and increase contrast to make the details pop, featuring a durable-surface treatment that filters out and blocks certain light waves. Polarization is perfect for long days on the water, fishing, boating, or any conditions where you’re battling glare.

Read on to learn more about MTF testing, its benefits, common methods of evaluating lens resolution, and MTF and resolution testing components.

Since the introduction of linear system analyses to the optics field, demand for higher quality, higher resolution optical systems has increased. Designers and metrology scientists have turned to modulation transfer function (MTF) testing as a standardized method of optical system characterization.

An MTF test bench’s calculations are contrasted as a function of spatial frequency within a two-, or three-dimensional coordinate system. This function reveals how well-resolved an object is based on its size.
