systems: objectives

	Image Science MTF Test Station for Objective Lenses This system measures the optical performance of objective lenses at both infinite and finite conjugate distances.  The following measurements are offered:
	LSF MTF and PTF EFL and Distortion Transmission and Vignetting
	Measurements can be made using the following test targets:
	Pinhole Slit Crossline
	In the case of the pinhole and crossline targets, the MTF is calculated in both azimuths (tangential and sagittal) simultaneously. Image capture is performed by a high-quality digital monochrome camera. Several types are offered:
	Matrix EL (Entry Level) - 780 x 582 x 8 bit 1/2 inch (Firewire) Matrix SD (Standard Level) - 1392 x 1040 x 8-bit 2/3 inch (Firewire) Matrix PL (Plus Level) - 1344 x 1024 x 12 bit 2/3 inch (Firewire / cooled)
	The system is based on a modular construction, and can be adapted and expanded to meet different test requirements and future needs.
