Traditional laser interferometers typically require a target mirror on the measured object to reflect the measurement light for high-precision results. Raytech's LY1000 non-contact laser feedback interferometer eliminates the need for a target mirror, achieving high-precision measurements simply by utilizing the faint reflected or scattered light from the object being measured. This is truly non-contact measurement. In addition to being suitable for measurement targets that traditional laser interferometers can handle, it is also ideal for measuring objects that are not suitable for mounting a target mirror, such as liquid surface heights, semiconductor wafer positions, micro-mechanical displacements, material expansion coefficients, vibrations, and more.

Here are the unique technical features or characteristics of this product:

1. High sensitivity, capable of non-contact measurement for uncooperative targets

2. The准com road technology effectively suppresses the drift caused by internal environmental changes in the instrument, which has a smaller zero drift.

3. Offers high resolution and wide range, with traceable measurement results.

The LY1000 Laser Feedback Interferometer offers a resolution down to the nanometer level and a range of up to 2 meters, expandable to several meters with an auxiliary beam expander. Like other interferometers, its measurement results can be traced back to the light wavelength, eliminating the need for calibration.

The product consists of a laser sensor, a signal processing cabinet, and software.
