	IR  MTF TEST STATION When the Image Science IR MTF Test Station was developed in 1994 it introduced new levels of speed, accuracy, and ease-of-use, to the measurement of Infra Red optics - advantages that it maintains to this day. The system is based on a single-element detector which is scanned across the image of a target slit to produce a Line Spread Function. At the end of the scan the MTF is calculated by the PC in just a few milliseconds. The total time for scanning the LSF, and calculating the MTF, can be as low as 3 seconds, with typical times less than 10 seconds. This fast-scan capability also dramatically reduces the times for image location and through-focus MTF scanning. Systems can be provided to measure objective lenses (one infinite conjugate) and telescopes (two infinite conjugates) up to a diameter of 500 mm. Like all Image Science systems, the IR Test Station is based on a modular construction, and can be adapted and expanded to meet different test requirements and future needs. Key features:
	Fast scan times, 3 -10 seconds typically MTF accuracy +/- 2%, repeatability +/- 1% EFL and Distortion Transmission and Vignetting
