The TEC series of Industrial microscopes is the missing link in the family: Incident light microscopes for material sciences, ready to handle semiconductors, LCD panels and wafers with a clever Bright field/Darkfield illumination concept. To extend the application fields for compound materials, microscope models with additional Transmitted light by integrated LED illumination can be chosen.
The TEC models offer a high value for the inspection of semi conductors and compound materials especially in technical education and quality control of industry. Bright field, Darkfield and simple Polarization contrast are combined with a new segmental illumination. This concept allows an oblique incident illumination, perfect for the detection of scratches or other defects on flat and reflecting surfaces without a need to move the sample.
The TEC BD models feature LD Plan BD objectives with a superb imaging performance, mounted on a 5-fold encoded nosepiece. The light intensity for each objective position is automatically memorized and will be repeated once the objective is swung in again.
The compact Epi illuminator carries a slot for polarizer and analyzer, ready for Polarization contrast and to reduce internal reflections. The illuminator also includes the controls for varying the incident light in terms of mode (BF or DF) and illumination angle. The extended 22mm Field of View (FOV) offers 21% more visual area in comparison to a basic 20mm FOV system. Both trinocular versions (25° viewing angle) display an erect/upright image as a basic feature, highly appreciated in industrial applications. The beam split is fixed by 50/50 (vis/photo).
The TEC is clearly focused on material sciences. Incident illumination is performed by a 3W LED of selectable color temperature. The incident/transmitted stand type additionally carries a transmitted LED illumination system with 39 LEDs mounted in an LED condenser. For compound materials, a simultaneous illumination is possible. Here, a stage with glass insert will be applied. 2 stage options (3x2”, 6x4”) give flexibility for different sample dimensions.
