Laser Interferometer micro PLR3000
Introducing the PLR3000 Series Fiber-Optic Laser Ruler
Take your precision measurement to the next level with the PLR3000 Series – a cutting-edge fibre-optic laser ruler engineered for ultra-high accuracy, exceptional stability and versatile integration.
Why Choose the PLR3000 Series?
Unmatched precision: With linear accuracy down to 0.2-0.5 ppm and resolution up to 10 nm, the PLR3000 sets a high bar for non-contact position feedback in demanding industrial environments.
Superior stability: Its ultra-stable He-Ne laser source delivers frequency stability of 0.02-0.05 ppm, while the remote fibre-optic delivery lets you position the measuring head independently of the laser unit—minimising thermal disturbances and Abbe errors.
Flexible multi-axis design: Choose from single-, dual- or triple-axis configurations, plus a full range of interference heads (prism/angle mirror, plane mirror, differential, head-only) to suit tight spaces or complex geometries.
Robust and compact: A modular setup separates the laser emitter (connected via a 3 m shielded fibre) from the head-module—ideal for tight machine tool environments. Compact format supports minimised Abbe offset for maximum accuracy.
Seamless system integration: Digital orthogonal outputs or 1 Vpp sine signals ensure compatibility with modern controllers; environmental compensation (via built-in station sensing temperature, pressure & humidity) keeps performance consistent.
Tailored to your application: Whether you need precise interferometric measurement or high-performance closed-loop position feedback, the PLR3000 Series gives you the flexibility to address micro-electronics, micromechanics, micro-optics, lithography and aerospace-grade applications.
