Optomechanics

Optomechanics

Optomechanics are the mounts, posts, and bases that interface between the optics in your system or experiment and the work surface (e.g. optical table).  The main jobs of these components is to 1) hold the optic securely over time, 2) allow positioning the optic coarsely to the optical axis height), and  3) for adjustable mounts, enable fine, high-resolution alignment of the optic to the optical beam.  There are unique fixed or adjustable mounts for each different type of optics to be held: mirrors, lenses, filters, prisms, beam splitters and more.  Each mount has different optic mounting methods and different adjustments depending on the type of optics held.  For example most lens mounts hold the optic with a retaining ring contacting the curved optical surface to ensure it is self-centered in the mount.  Lens mounts typically have linear adjustments for centering (xy) and focusing (z). Higher end mounts also include pitch and yaw angular adjustment for more exact alignment.  Another important element of the optomechanics are the mounting posts and bases.  While these are simple parts, they provide an important function for an optical mounts - connection to the work surface.  There are two main types of mounting posts: fixed-height and height-adjustable.  The fixed-height posts provide the most stability simply because there are no moving parts.  The most widely used fixed post type are called pedestals due to their wide base.  Pedestal posts require a clamp fork to mount to an optical table.  Standard post and post holders provide manual height adjustment and are comprised of a post holder and a post which fits inside of the post holder.  This arrangement allows for height adjustment as well as rotation adjustment (yaw).  Post holders have threaded bottoms to allow mounting directly to the threaded holes on an optical table.  While this mounting is convenient, it restricts the location of a post holder to one of the threaded holes on the optical table; note that pedestal posts do not have this limitation due to the fork clamp mounting.  For a post holder, this limitation can be overcome with the addition of a mounting base which enables fork-like mounting.   Optomechanics are used in one way or another in every optical application or experiment.  Although OptoSigma has thousands of these components,  if one of our many catalog items does not meet your requirements, send us a request for a custom version. 

  • Mirror Mounts

    Description

    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.

  • Optical Cages

    Description

    OptoSigma’s CAGE Systems come in three (3) standard sizes, P16 (diameter: 4mm rods, 16mm pitch between the rods), P30 (diameter: 6mm rods, 30mm pitch between the rods) and P60 (diameter: 6mm rods, 60mm pitch between the rods). Our systems are compatible with industry standards, though, our intent was to design and build cage systems that are more stable and accurate vs. others on the market today. A unique feature is the ability to place and remove individual components by “Dropping them In-Place” when 3-rods are utilized. This is highly unique and convenient. You can then add the 4th rod to finish the assembly. A large selection of accessories and adapters are available for integration into optical setups using mounting posts or lens tubes.  Optic holders and accessories are supported by four (4) rigid steel rods (CAGES) to mount optical components along a common optical axis.  In addition, the optic holders can split the optical axis and the cage into two or fold it to 90 degrees.  The CAGE system has no distinction of orientation.  Therefore, it is possible to place the holders in various orientations, which is convenient for constructing a three-dimensional optical system.
