Optical Micrometer – Five Lab Co. Ltd.
The Optical Micrometer is a non-contact, non-destructive tomographic measurement device using Michelson interferometry.
Optical micrometers are devices that irradiate light onto a sample, detect the return light from the surface, interior, and back surface, and measure the distance between each return light. Since it is a reflection measurement, it has a high degree of freedom and is non-contact. If the sample is transparent to the measurement light, the internal state and sample thickness can be easily measured.
Features
1) Non-contact and no damage to the sample
No damage to the sample.
2) Reflectance measurement, so only one side of the sample is measured.
High degree of freedom of measurement, thickness and internal measurement are also possible if the sample is a transparent sample.
3) High-speed measurement – Measurement is performed at 25 Hz.
4) Use of fiber interference system
Compact and vibration-resistant, ideal for on-site use
Stability
S-BSL7(OHARA) This is an example of continuous measurement of a flat plate of t=1.010mm for 5 hours. The positions of the beat signals on the top and bottom surfaces of the sample vary by ±20 μm due to the influence of room temperature.
The position of the beat signals on the top and bottom surfaces of the sample fluctuates about ±20 μm due to the influence of room temperature, but the signal spacing (sample thickness) is stable within ±1 μm.
Reproducibility
This is an example of measurement reproducibility of a flat plate of S-BSL7(OHARA) t=1.010mm and 2.000mm, measured 10 times.
(Samples were set and measured at 20-minute intervals each time.) It can be confirmed that the range is within ±1μm stably.
Example of non-contact, micro-area measurement
The measurement light beam diameter of the optical micrometer is The parallel beam diameter is Φ0.8mm and the focused beam diameter is 0.03mm, allowing accurate measurement of the thickness of micro concavo-convex lenses, which are usually difficult to measure, without damaging the lens.
