Image Science's two MTF analyzers are designed for testing in the 1-3 micron region. They can be used as additions to an existing MTF measurement station, or can be delivered as a complete solution. The first unit is a real-time device typically outfitted with an InGaAs camera that covers the 0.9 to 1.7 micron range. The second unit is a scanning system covering the 1.0 to 3.2 micron range. It uses a lead sulphide detector and sampling aperture.
The Matrix series comprises digital camera detectors designed specifically for real-time MTF measurements in the visible and near-infrared (NIR) wavelengths. These cameras are available in three models with variations in sensor size and pixel resolutions. They can be used in a variety of applications such as routine production testing, or research and development work.
The MS1002/00 MTF starter kit has been designed for users with an optical table or bench and standard positioning equipment who want to subject lenses to MTF testing/measurements.
MTF is a quantitative and objective measure of the quality of an image formed by a lens or and electro-optical system. This measurement is appropriate for lenses of all qualities and can be calculated from lens design data, which enables theoretical and actual performances to be compared.
A high-quality lens begins with a good design, tolerant to small manufacturing errors. The manufacturing process must be tightly controlled, from individual lens elements to final assembly. But, since small errors in manufacturing can result in serious loss of performance, end-of-line testing is necessary.
This datasheet includes an image of Image Science’s infrared transmission system and information on its features. This system measures the transmission of small IR lenses in the LWIR and MWIR waveband.
Modulation Transfer Function (MTF) Systems help system designers predict the actual image-forming capability of an optical system. These systems compensate for image degradation caused by inevitable aberrations and diffraction phenomena.
Image Science was formed in 1991 and specialises in the design and manufacture lens testing systems for both Research & Development and production applications. We concentrate on providing the best combination of accuracy, speed of measurement, and ease of use.
In particular, we specialise in the measurement of MTF (Modulation Transfer Function) which is the most widely used measure of image quality. However, in addition to MTF, we also measure a wide range of other optical parameters, including:
Our systems are available for the following regions of the spectrum:
Each one of our systems is configured to suit the customer’s particular requirements, and is supplied in a modular form which allows for later upgrading. Systems are often motorised, and can be programmed to perform automatic testing for high-volume production testing if that is required.
Our systems have been installed all over the world, and our customers include small and large companies, defence contractors, and government agencies.
