The ilet collimator from CI Systems is a reflective off-axis parabolic collimator for testing electro-optical payloads, imagers, and sensors from 0.4 µm to 15 µm. Clear apertures of 4–6 inches, focal lengths of 15–40 inches, and diffraction-limited on-axis performance support repeatable MTF and alignment measurements.
Optical test engineers rely on this ilet collimator when they need broadband, diffraction-limited collimation for imager and payload evaluation.
Overview: Intermediate-level optical tester with a reflective off-axis parabolic mirror for versatile depot and field testing.
