Material Low thermal expansion glass Due to their custom configuration and dimensions, plane mirrors are special order items only and therefore may be subject to longer lead times and minimum order quantities. Mirror mounts To enable mirrors to be mounted and correctly aligned to the motion system, Renishaw can also provide adjustable mounts for use with mirrors up to mm in length, which have a cross section of 25 mm x 25 mm.

Mirror mounts To enable mirrors to be mounted and correctly aligned to the motion system, Renishaw can also provide adjustable mounts for use with mirrors up to mm in length, which have a cross section of 25 mm x 25 mm.
Actual adjustment range is dependent on mirror length. Features and benefits Easy to align - in-built pitch and yaw adjustment to accelerate the mirror alignment process.
Stable mounting - to provide a stable foundation for the mirror whilst allowing it to thermally expand as required. Non-restrictive - only clamping the mirror securely on two faces reduces the stress through the mirror, minimising the risk of bending the mirror once mounted.
Renishaw supplied mirror mounts are not vacuum compatible. A vacuum chamber window then allows the laser beams to pass between the detector head and the measurement mirror. Vacuum chamber windows can also be used with other interferometer head variants where the RLD is required to measure within a vacuum chamber, such as RVI20 vacuum compatible interferometer.
Whilst Renishaw do not manufacture vacuum chamber windows, the 39 mm vacuum chamber window has been sourced to a custom specification to maximise the performance of the RLE system.
Mounting recommendations Renishaw recommends the following when mounting the chamber window within the chamber wall. The window must not be mounted under tension which could cause the window to distort and the beam to deviate from the nominal.
An O-ring must be used on at least one side of the chamber window to create and maintain a seal in the vacuum chamber wall. The assembly uses two mirrors to increase the offset by 15 mm to produce a total separation of 29 mm standard RLDX3-DI offset is 14 mm.
Features and benefits Increased offset - allows for an additional 15 mm offset between the measurement and reference beam. Highly reflective - utilising highly reflective mirrors minimises the signal strength drop between the measurement and reference beams.
Standard mounting - the periscope maintains the standard DI head mounting. RVI20 vacuum compatible interferometer The RVI20 is a vacuum compatible interferometer assembly for plane mirrors, which when used with a Renishaw RLDA3-XX detector head offers the ability to keep the entire measurement path within the vacuum environment.
Features and benefits Relative measurements - allows for relative measurements between two parts of the machine, such as tool and workpiece. Vacuum compatibility - compatible with high vacuum applications and is suitable for mounting within the vacuum chamber.
High quality optics - the RVI20 contains Renishaw's high quality interferometer optical assembly normally used within the RLD detector head. RVI20 has been developed for use in laser encoder applications where the measurement path is required to be within the vacuum environment.Lenses and Mirrors A lens is a transparent device with two curved surfaces, usually made of glass or plastic, that uses refraction to form an image of an object.

Advanced Optics optical mirrors are excellent performers in aerospace, military and commercial avionics, scientific and medical instrumentation, academics and research, as well as industrial applications. Optical Mirrors are designed to reflect light for a variety of applications, including beam steering, interferometry, imaging, or illumination.
Optical Mirrors are used in a wide range of industries, such as life sciences, astronomy, metrology, semiconductor, or solar. eduMedia / Lenses and mirrors. Mobile ×.
