All About Optical Cage Systems


When one looks around, he/she is encountered with optical devices all around. Optomechanics, the combination of optical and mechanical engineering, are behind the development and design of optical instruments and devices. The microbench cage system is a vital element of several optomechanical setups used in the optical device.

What is it all about?

The Microbench cage system is an accurate, compact, and innovative replacement for the triangular rail system. It is considered perfect for all kinds of spatial structures in compact form because of the following features:

  • Simple integration procedure
  • Small in dimensions
  • Easy and hassle-free expanding
  • Long-lasting and rugged

Optical devices everywhere

Optomechanical engineers are responsible for combining optical and mechanical engineering to create optical devices like camera zoom lenses, lasers, spacecraft instruments, and so on. The popularity of the microbench cage system has reached new heights in high-tech industries and advanced engineering technology sectors.

Challenging development of optical instruments

In the majority of cases, the optical devices and instruments have to abide by stringent requirements concerning size and shape along with the resistance to different kinds of external factors. This makes the creation and production of optical devices and instruments a big challenge. The microbench cage system engineers and experts are required to come up with a resolution by incorporating the understanding of physical properties of light and the working principles of optomechanical engineering.

About the optoform cage system

Optoform or cage system offers multiple optomechanical elements that are put together in different configurations to develop a range of optical instruments. It is an essential industrial aspect of manufacturing and producing various optical devices and tools. This is the new industry standard, considered a better and more efficient version than conventional cubic optical systems.

Concentric bore design

The microbench cage system incorporates a concentric bore blueprint enabling the interlinking between mounts. Rods are used along the optical axis or at right angles of the mounts through the connectors located at the corners. Thanks to the circular design that enables simpler, and hassle-free optical component assembling. The assembling is catered in a more natural pattern with other optical elements like lenses. The concentric bore is also used for linear bearings, micrometers for accurate linear, and X-Y position of optical components.

Functioning of cage system

The optical instruments and devices need to function in all types of circumstances. They might have to deal with myriad loads and even fit in tight spaces. The tolerance specifications are challenging to cater to, thereby making optical systems very complicated. The use of precise simulation models helps to assess and determine the performance of optical instruments subjected to extreme changes in temperature, pressure, external loads, etc.

The engineers need to understand the fundamental physics of optomechanical mechanisms and the simulation process to evaluate the design properties and their interactions. The simulation models are highly precise aiding in eliminating design loops and physical mock-ups.

Applications  of cage system

Optical instruments and devices that are based on conventional optical setup are becoming useless instruments. Optoform enables optical experts and researchers to create results without molding any customized elements. The microbench cage system has multiple applications, widely utilized and accepted around the world.

It is used in research and educational laboratories for constructing new ideas and setting up optical instruments and tools. The self-holding feature makes the microbench cage system ideal for marketing customized optical instruments and equipment at lower expenses. Some of the high-tech instruments developed are:

  • Telescopes
  • Eye surgery apparatus
  • Instruments for biomedical usage
  • Spectroscopy
  • Third-generation harmonic microscopy
  • Vacuum experiments
  • Fiber optics setups
  • Imaging systems and devices
  • Stellar interferometers


Depending on the applications, it can be determined whether the microbench cage system is a good option or not. Cage systems have emerged as a convenient option for a wide range of optical devices and instruments, especially where the light travels along the axis and the setups that don’t require any change at all. For example, microscopes, collimators, beam expanders, and so on. Cage systems are usually not the correct choice in optical instruments and devices where the light gets mirrored at an impulsive angle. The best example is the cases with laser lights, and mirrors that reflect whimsically. Moreover, it is also not ideal where the optical instruments demand frequent changes and readjustments.
