THE MTF TEST AND MEASUREMENT COMPANY

Image Science

Image Science designs and manufactures optical test equipment for assessing the quality of visible and infra-red lenses. Parameters measured include:

Our benches can be supplied for Research and Development applications, or for Production Testing.

Image Science was formed in 1991 and is in its 27th year of business.

Image Science offers a comprehensive range of optical test equipment for MTF measurement and other performance-related parameters. Our benches can be adapted to suit your individual requirements, if your system forms an image, we can assess it! In addition to MTF we can also measure the following optical parameters: PTF, LSF, EFL, FFL, FOV, Distortion, Field Curvature, relative and absolute transmission. Our benches can be supplied with sources and detectors for the following spectral bands: Visible, NIR, SWIR, MWIR, LWIR. Image Science also offers an in-house MTF testing service for customers who wish to test pre-production prototypes.

Our state of the art equipment meets industry standards and offers fast and accurate measurements at all times. Our benches can be used for research and development, as well as for testing the performance and quality of lenses in production.

Established in 1991, we have enjoyed 26 years in the business and have a wealth of knowledge and experience as a result. You can therefore be confident in our ability to supply the testing equipment that would best suit your needs.

Image Science: Your Partner in Lens Quality Assurance

In today's ever-expanding imaging landscape, ensuring the quality of your lenses is paramount to your success. At Image Science, we understand the critical role that lenses play in capturing high-quality images for both commercial and military applications. That's why we've dedicated ourselves to providing a comprehensive suite of lens testing equipment and services to meet the diverse needs of manufacturers, designers, and quality control professionals.

MTF Testing and beyond: A Deeper Dive into Our Testing Capabilities

While MTF measurement (Modulation Transfer Function), PTF (Point Spread Function), and EFL (Effective Focal Length) are fundamental lens quality metrics, Image Science goes beyond these essential measurements. Our advanced equipment and expertise enable us to perform a wider range of tests, including:

• Distortion: We assess the extent to which straight lines appear curved in the final image. This is particularly important for architectural and landscape photography, where maintaining straight lines is crucial.
• Vignetting: This test measures the falloff of light towards the corners of the image. Excessive vignetting can result in darker corners, detracting from the overall image quality.
• Chromatic Aberration: This test measures the lens's ability to focus different wavelengths of light at the same point. Chromatic aberration can manifest as colour fringing around high-contrast edges, degrading image sharpness.
• Resolution: We assess the lens's ability to reproduce fine details. Resolution is often measured in line pairs per millimetre (lp/mm) and is a key factor in determining the overall sharpness of an image.
