LSM-902/6900 Laser Scan Micrometer

LSM-902 (Measurement unit) & LSM-6900 (Display unit) are the most accurate

1" (25mm) measurement range Laser Scan Micrometer in the world.

LSM-902

Adjustable Workstages (optional)

LSM-6900

Features:

■

Measuring range – .004 to 1" (0.1 to 25mm) covers most precision parts.

■

Repeatability – ±.000002" (±0.05µm) highest repeatability for a 1" (25mm) LSM in the world.

■

Linearity – ±.00002" (±0.5µm) over the entire range, and higher linearity in the small range.

■

High Resolution – Improves measurement accuracy

■ Stable edge detection by using new algorithm.

■

Multi-function type display.

[*1]: Accuracy inspection environment/Temperature 20°C±1°C, Humidity: 50%±10% [*2]: The repeatability is determined by the value for ±2

σ at the measurement interval of 1.28 sec.

[*3]: Specified at the center of the measurement region. [*4]: ▲ D: Diameter difference to master gage. [*5]: An error due to workpiece shift either in the optical axis direction or in the scanning direction.

[*6]: The area given by [measuring range on the optical axis] x [measuring range in the scanning direction.] [*7]: The combination of functions is limited, details are described in the user's manual.
