Chromatic Sensors
Frequently Asked Questions
A chromatic sensor is an optical metrology tool that measures displacement or thickness by detecting changes in wavelength. It is a non-contact method of measurement that is used in a variety of applications, including semiconductor manufacturing, medical devices, and aerospace.
A chromatic sensor works by measuring the distance between a light source and a reflective surface. The light is passed through a fiber optic cable and then through a diffraction grating. The reflected light is then compared to the original light to determine the distance.
Chromatic sensors offer high accuracy, repeatability, and resolution, making them ideal for use in industries where precision is crucial. They are also non-contact, which means they can be used to measure delicate or fragile objects without causing damage.
Chromatic sensors are used in a variety of industries, including automotive, aerospace, semiconductor manufacturing, and medical devices. They can be used to measure thickness, distance, and vibration, among other things.
When choosing a chromatic sensor, it is important to consider factors such as accuracy, resolution, measurement range, and environmental conditions. It is also important to choose a sensor that is compatible with the material being measured and the desired measurement method.
