LMI Gocator 4000 Review Summary
Sensors that view the surface at an angle leave shadows beside tall or steep features. The Gocator 4000 sends and receives light along the same axis, so it sees into holes and beside steps and measures slopes of up to 85 degrees. Lateral resolution reaches 1.8 µm, finer than any other Gocator line, at rates of up to 36 kHz. The field of view is tiny, 3.45 mm or 5 mm, and the sensor weighs about 10 kg. This is a tool for semiconductor packages and miniature electronics.
Pros
Shadow-free coaxial measurement
X resolution from 1.8 µm
Slopes up to 85 degrees
Scan rates up to 36 kHz
Measurement inside the sensor
Cons
Field of view of 3.45 or 5 mm only
About 10 kg
Short clearance distance
Who It Is For
The series fits semiconductor and electronics manufacturers who must measure steep, deep or mirror-like micro-features inline.
