- MRTD measurement without a PC
- Robust, athermal design
- Portable & easy to use
The ILET (Intermediate Level Electro-optical tester) family of test systems are most suitable for performing optical and boresight tests in the field or in the laboratory. ILET is compact, computerized may be used as a mobile test station (van mounted) and enable full testing of thermal imagers and visible sensors without recourse to the D level.
The most common ILET configuration includes the collimator, an optional light source (blackbody and/or visible light source), and a target wheel (manual or motorized). As an additional option the tester may include a computer with CI’s test software.
The ILET testers are easy to use when interfaced with CI’s software, minimizing the turn around time and maximizing testing objectivity and repeatability. The testers are designed to retain their accuracy over a wide range of temperatures. The ILET’s outstanding features and versatility make them usefull in a variety of applications such as testing inside environmental chambers, testing on production lines or testing in the field.
