Scanning Image Analyzers

Ask about our new SD-800/900 Image Analyzers for measuring folded optics!

A knife-edge scanning system is inherently more flexible for testing a wider range of optical systems. There is a larger variety of single element detectors available when compared with array detectors. Collection and relay optics do not need to provide the image quality that is required by video analysis.

With the EROS Image Analyzer, relay optics collect light from the test optic’s image plane and project it onto the detector. Scanning image analyzers include a detector, a matched preamplifier, collecting optics, and aligned mounting fixtures. The infrared detectors are LN cooled with a temperature sensor built into an 8-hour hold time dewar package. The relay lenses supplied will collect up to 400 μm spot sizes up to F/0.7.
