Specular Reflective Sensor Provides High-Resolution Accuracy

Capable of measuring surfaces ranging from perfect mirrors to silicon wafter, stainless steel and other reflective materials, the Class II LMI Selcom SLS 700 Specular Reflective Sensors have a precise 10-nm over 1-mm measurement range, fast 16 kHz sample rate with the company's "Fast Light Control Circuit", and a small 10 to 20 micron visible laser spot that enables profiling of intricate target structures such as miniscule cracks and grooves.
The sensor features a built-in digital processor for data averaging and filtering contained in a separate controller unit that easily interfaces with the sensor head. Its compact and ruggedly designed imaging optics, integrated electronics, careful mechanical layout, and conditioned electronic signal provide suppression of speckle noise and target structure influences.
