Mirror Mounts

Mirror Mounts

Mirror mounts provide a means to adjust the angle of a mirror on two axis: the pitch axis (up and down) and the yaw axis (side to side).  They are available in many sizes to hold mirrors ranging in diameter from 12.7 to 300mm.  The most widely used, cost-effective, and stable mirror mount is the kinematic type.  Its design is fairly simple, providing single constraints in each of the six degrees of freedom, ensuring excellent stability in temperature varying environments.  Gimbal mounts are another type commonly used mount which provides an exceptionally angular adjustment range as well as the ability to minimize adjustment cross-talk and beam translation. Mirror mounts are used in almost all optical applications primarily for beam routing, or in other words, getting the optical beam from the source to the point of interest.  Industries that utilize these mounts include research, bio-medical, life sciences, astronomy, metrology, semiconductor, and more.   If one of our many catalog mirror mounts does not meet your requirements, just send us a request for a custom version.

  • Standard-Grade Kinematic Mirror Mounts

    Description

    Standard Grade Kinematic Mirror Mounts are low-cost mirror mounts intended for general purpose use such as teaching labs and less demanding applications such as imaging or remote sensing. You will find a selection of mounts to hold ½”, 1”, 30mm and 2” mirrors. Despite the super low cost, these mounts are high quality and yield solid performance. Need something similar? Ask our sales team about modifying to meet your requirements.

  • Performance-Grade Kinematic Mirror Mounts

    Description

    Performance Grade Mirror Mounts are kinematic mounts that provide a higher level of stability and fine adjustments for more demanding applications. We have (2) families of mounts in this section. The “Kinematic Mirror Holders” have “MP” series that are 2-point adjustment with resistance locks and the “HS” series are 3-point adjustment with larger diameter knobs to enable more fine positioning. The other family are virtually the same mix of mounts that incorporate our patented NOMI LOCKTM mechanisms. The NOMI LOCKTM are highly effective non-influential locks. The bushing can be rotated in either direction to lock the screw(s) in place.

  • Precision-Grade Stainless Steel Mirror Mounts

    Description

    Precision Grade Stainless Steel Mirror Mounts are intended for applications where the highest level of stability is required. Applications such as interferometry and laser cavity systems often fall in this category. In this section, you will find a variety of mounts such as “C-Shape” for close-proximity and open architecture, in addition to mounts that are designed, manufactured, and packaged for use in high vacuum applications. Finally, our new flagship mounts, the MHX, available in many sizes and highly unique in their features, such as center post mounting, epoxy wells and hollow frame design yielding high stability and low thermal drift. If you are looking to automate any of these mounts, please contact our sales team to discuss integrating motorized actuators.

  • Top-Adjust Mirror Mounts

    Description

    As optical systems become more complex, real estate on the optical bench becomes more and more valuable. As laser powers get higher and higher, operator safety becomes more critical. Top adjust Mirror Mounts address both of these concerns by providing access to the adjustments from directly above the mount. This allows the components to be mounted closely on the optical bench and keeps hands and fingers out of the beam paths. In this section you will find a large variety of top adjust mounts from kinematic to gimbal and for optical benches or OEM’s alike. Can’t find what you are looking for? Reach out for support and let us help you find a solution or design a complete custom to meet your requirements.

true_gimbal_mounts
True Gimbal Mounts

Gimbal mounts have axes of rotation (pitch and yaw) which intersect at the center of the surface plane of the optic so that the beam length will not change during adjustment. True gimbal mounts always have rotation axes that are true (parallel and orthogonal) to the mounting surface. This configuration eliminates cross talk between the adjustments.
