NCG-2

Product catalog summary
Overview: The NCG-2 Gauge is a non-contact measurement instrument designed for precise dimensional measurement of fragile, soft, or highly polished materials. It is particularly useful in semiconductor, optics, and electro-optics applications.
Specifications: The NCG-2 features a measuring range of +/- 1.25mm with a display resolution of 0.1 micron. It operates with clean instrument air or inert gas at 2 bar pressure, consuming 0.2 cfm. The digital display is a 4.5 digital LED showing measurements in microns. The system includes a built-in 0.5 micron filter to minimize contamination.
Key Features: The gauge uses a linear voltage differential transducer (LVDT) and a pneumatic servo to maintain a fixed air gap, ensuring no contact with the sample surface. It is equipped with a stable probe stand and a hand-operated probe tip lifter. The system is available in two sizes, accommodating wafers up to 4” or 8”.
Operation: The NCG-2 is simple to operate, with a probe lift drop mechanism and color-coded LEDs indicating measurement status. It allows for quick and easy multiple measurements over a wafer surface.
Accessories: Various vacuum chuck faces and vacuum systems are available for use with the NCG-2, enhancing its versatility for different substrate sizes.
Technical Specifications: The gauge has a gauging force of 15-20 grams and weighs 15kg. The electronic/pneumatic control module dimensions are 250x190x186mm, and the stand dimensions vary depending on the model.
