Posts and Post Holders for Stable Optical Mounting
Frequently Asked Questions
What are opto-mechanical posts and holders used for?
Opto-mechanical posts and holders are critical components in photonics and laser systems, providing precise positioning and stability of optical elements. They are often used in laser beam delivery systems, interferometers, and microscopy setups.
What materials are opto-mechanical posts and holders typically made from?
Opto-mechanical posts and holders can be made from a variety of materials, including stainless steel, aluminum, and titanium, to meet the specific needs of different applications.
What is the difference between a post and a holder?
Opto-mechanical posts are typically cylindrical rods with threaded holes or slots for attaching optical components, while holders are designed to securely fasten posts to a base or surface.
How do I choose the right opto-mechanical post and holder for my application?
Choosing the right opto-mechanical post and holder depends on various factors such as the required precision, stability, and load-bearing capacity.

Overview of Posts and Post Holders
Posts and Post Holders are mechanical components used to position and secure optical mounts, mirrors, lenses, and other photonics hardware on an optical table or breadboard. In light transport systems, these elements provide the rigid support needed to maintain beam alignment over time and under varying environmental conditions.
A typical setup combines a cylindrical post with a matching post holder that clamps the post and fixes it to a baseplate. Together, Posts and Post Holders define the optical axis height, rotation, and lateral position with repeatable precision.
Post Holder Sub-Type
The primary sub-type currently available in this category on FindLight is the Post Holder. Post holders are sleeves or clamps designed to accept standard-diameter posts (for example, 0.5 in or 12 mm). They often include a side-located clamping screw and may provide fine height adjustment by sliding the post before tightening.
- Mounting interface: Commonly features a counterbored or tapped hole pattern for direct attachment to optical tables, bases, or carriers.
- Material and finish: Typically stainless steel or black-anodized aluminum to reduce reflections and provide mechanical stability.
- Height range: Determined by the compatible post length and the holder’s clamping span, defining the usable vertical adjustment range in assembled Posts and Post Holders.
Key Selection Criteria for Buyers
When specifying Posts and Post Holders for a lab or production setup, compare the following parameters:
- Post diameter compatibility: Ensure the post holder bore matches your existing posts and mounts.
- Clamp mechanism: Side screw, split-clamp, or spring-loaded designs affect rigidity and ease of adjustment.
- Thread type and base pattern: Check for metric or imperial threads and hole spacing compatible with your optical table.
- Load capacity and stability: Higher-mass optics or long beam paths require stiffer Posts and Post Holders to minimize drift.
On FindLight, you can review detailed datasheets, compare technical specifications across available Posts and Post Holders, and request quotes from multiple suppliers directly. Quotations can be requested without registration, enabling rapid evaluation and sourcing for your optical and light transport assemblies.
