An optical micrometer is a type of measurement sensor that uses light to capture the silhouette of a target and measure its dimensions.
It consists of a transmitter and a receiver that are aligned opposite to each other. The transmitter emits a beam of light (usually from a high-intensity LED) and the receiver captures the image of the target as it passes between them. The receiver uses a telecentric lens and a high-speed CMOS to process the image and calculate the measurements.
Optical micrometers can measure various parameters such as diameter, width, height, angle, position, etc. They can also measure multiple targets simultaneously and provide high-speed and high-accuracy results. Optical micrometers are widely used in industries such as automotive, aerospace, electronics, medical, etc.
An optical microscope is a different device that uses visible light and a system of lenses to magnify images of small samples.
It has an eyepiece and an objective lens that work together to create a magnified image of the sample on a focal plane. Optical microscopes are the oldest design of microscope and are used for observing biological specimens, materials, etc
Some of the advantages of optical micrometers over other types of sensors are:
The Global Optical Micrometer market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
KEYENCE offers LS-9000 Series high-speed optical micrometres are extremely durable and provide the sampling speed (16000 samples/second) and repeatability (0.03 m) needed for accurate inline measurement.
These sensors have no moving parts due to their specialised optical design, which includes a high-intensity LED and telecentric lenses, and hence provide precision throughout a long service life.
Its high speed, accuracy, and durability enable robust inline and offline measurement in a wide range of settings and target materials. The high-speed exposure produces excellent photos of moving targets, allowing for accurate measuring of wires and other vibrating things.
