Stable Measurement Regardless of Surface Conditions

The confocal measurement system detects only peak beam reflection and ignores beam intensity, which could vary depending on surface conditions Therefore, the color, luster, and texture of the target surface will not affect measurement.

Smallest Spot Size and Longest Distance

With a 2μm or 7μm diameter laser beam spot and a working range of 5 mm or 28 mm (depending on the model), the LT Series easily spans the distance required between sensor head and target for most applications.

Thickness Measurement of Transparent Materials

A single sensor head mounted at the side of the target can be used to measure thickness. Unlike conventional displacement meters, the LT Series requires no additional sensor head on the opposite side. By detecting the peak beam reflection from the top and bottom surfaces of the target, it achieves accurate measurement with ease.

Microscope Function

High-speed auto-focus lens ensures clear captured images. The sensor head incorporates a miniature CCD camera. During measurement, a 9-inch monitor can be used to display the target image at 85X magnification.

Waveform Monitor

Real-time display of measured values. settings on a single screen.

Resolution of 0.01μm (0.0004 Mil) and Linearity of ±0.5%*

The LT achieves these specifications with almost any target.
*Resolution of 0.1μm (0.004 Mil) and linearity of ±0.3% with Model LT-9030.

Accurately Measures Wet Surfaces

Unlike conventional sensors, the LT can measure the thickness of wet coatings, eliminating the need to dry the target. As shown in the photo, even dewdrops can be measured accurately.

Ideal for Measuring Mirror-surfaced Targets

Conventional sensors cannot reliably measure mirror-surfaced targets such as metallic objects and compact discs, because no light is reflected at some angles or because the light-receiving element is saturated by excessive specular reflections from the target. The active confocal method, which detects the peak quantity of received light, ensures stable measurement even when the optical axis is inclined up to ±17°(Model LT-8010) or ±7°(Model LT-8110) toward the target.
