The modulation transfer function, also referred to as MTF, is a unique and interesting process. Moreover, MTF Testing and MTF Measurement are crucial in the resolution performance representation of an imaging lens. Basically, MTF tells us how good an optical system is performing. Without this, we cannot guarantee its high resolution.

It is important to note that MTF is a quantitative and direct measure of image quality. Optical systems, such as photographic optics, contact lenses, video systems, copy optics, photolithographic optics, and compact disk lenses, are measured via MTF. The end result of MTF testing is a description of an image structure with notes on its spatial frequencies. Furthermore, you can even isolate the several frequency components for a specific evaluation. Who benefits from modulation transfer function testing? Did you know that MTF can also be related to end-use applications? These said applications are very much reliant on the resolution ability, as well as the image integrity, at a critical dimension. The most in-demand lithographic and photographic lenses relate to the size of the image and the structure to the end application requirement. To give you an idea of how critical this is, imagine a video imaging system designed to consider the image size produced by the lens. There is a limit to the array pixel width but with the right lens which maintains a high MTF, it can actually go beyond this cut-off frequency. Some of the other advantages of MTF testing include it being ideal for modeling concatenated systems. Since MTF is analogous to the response rate of electrical frequency, it can allow the modeling of optical systems through the linear system theory. This is then employed through numerous phases resulting in the expected system performance. This type of testing is universal and objective, and it also offers the most straightforward process of measuring optical systems' integrated polychromatic performance. Here are the MTF testing benches available from Image Science: Ultra-Violet B (UVB) Near Ultra-Violet (NUV) Visible (VIS) Near Infra-Red (NIR) Short-Wave Infra-Red (SWIR) Medium-Wave Infra-Red (MWIR) Long-Wave Infra-Red (LWIR) How can Image Science help you with MTF measurement?
