RLU - Lightweight laser device with fiber optic transmission

Renishaw's laser device has high-performance measurement capabilities based on the principle of laser interference, and is as easy to install as traditional steel grating and glass grating.

RLE system

The RLE system is a zero difference laser interferometry measurement system designed specifically for position feedback applications. Each RLE system includes an RLU laser device and one or two RLD10 emission heads, depending on the specific application requirements.

The RLU laser device is available in two configurations: single axis or dual axis, including a HeNe (helium/neon) laser source, electronic devices for frequency stabilization, fiber optic conduction devices, and axis position feedback electronic devices.

With the help of Renishaw laser rulers, we are able to exceed the standards set by our customers and strive to provide them with the best possible experience; And the reason why we are able to continuously achieve success is partly attributed to the technological advancements brought by Renishaw.

Renishaw currently offers two models of laser devices, which differ in performance:

RLU10 laser device

The laser frequency stabilization accuracy of RLU10 within any hour is ± 50 ppb, and its performance level is suitable for most non vacuum environment applications.

Features and advantages

Combining RLU10 with a Renishaw launch head (RLD) suitable for the desired application has the following characteristics and advantages:

• Simple system structure -Utilizing Renishaw's fiber optic transmission system
• Quick adjustment of collimation -RLD emitter allows laser beam to be directly directed towards the measurement axis
• Compact structure and easy setup -The system takes up very little space and has a very short installation time

RLU10 Performance

XY platform application

Are you looking for a laser ruler suitable for XY platform applications in non vacuum environments? RLE10-DX-XG is an ideal choice for this type of application, which uses RLU10 laser device and two RLD10-A3-P9 (plane mirror interferometer 90 °) emission heads.

RLU20 laser device

The laser frequency stabilization accuracy of RLU20 within any hour is ± 2 ppb, which can provide excellent measurement performance for most vacuum environment applications.

Features and advantages

Combining RLU20 with a Renishaw launch head (RLD) suitable for the desired application has the following characteristics and advantages:

• Simple system structure -Utilizing Renishaw's fiber optic transmission system
• Quick adjustment of collimation -RLD emitter allows laser beam to be directly directed towards the measurement axis
• Compact structure and easy setup -The system takes up very little space and installation time

Relative measurement applications

Are you looking for a laser ruler suitable for relative measurement applications in a vacuum environment? The RLE20-DX-XP is an ideal choice for this type of application, which uses an RLU20 laser device and two RLD10-X3-DI (differential interferometer) emission heads.

Configure RLE system

To operate as a displacement interferometer, Renishaw's laser device needs to be connected to a suitable laser head. When defining an RLE system, the following options should be considered:

• Laser source (RLU10 or RLU20)
• Fiber length 3 m or 6 m (* RLE10)
• Calibration certificate (this option comes with additional fees)
• Flat optical mirror group or conical reflector optical mirror group
• RLD emitter types for each axis
• Beam output direction of each axis (not applicable to differential interferometer emitter)

To determine the order number for the RLE laser ruler system required for your specific application, simply input your application requirements into the order number generator. It will automatically calculate the necessary system order number, which can be used for inquiries or placing orders.
