Are there off-the-shelf mounts for very small 2mm lenses, smaller than M12 S-mount?

I’m looking for a mount for a very small lens in a custom camera project. The setup uses a CCD sensor and a single lens about 2 mm in diameter, and I already know the required mechanical position and tolerances.

I’d like to know whether there are standard miniature lens mounts available for this size, similar to those used in phone or camera modules mounted to a PCB. I initially looked at the Raspberry Pi camera style of mount, but I haven’t been able to identify a commonly available source.

The smallest off-the-shelf option I’ve found so far is M12x0.5 (S-mount). I tested some webcam-style female S-mount holders with small S-mount lenses, but the mechanical play was larger than expected for my application.

Are there standard lens mounts available below M12 for tiny sensors/lenses, and are these generally available in low quantities, or is a custom mount usually required?

I have checked Edmund Optics, and they do not offer mounts for such small lenses. Also checked Thorlabs, Newport, laser2000, Qioptiq, and they also don't have such mounts off the shelf. There is a possibility to make a custom S Mount.

Wikipedia Lens mount page states that for small camera modules there are Mounts from M12x0.5 all the way down to M4.2x0.2 (1/7" sensors). For example, 1/7" 2.0mm F2.8 Megapixel M4.2x0.2 mount, but minimum order is 100pcs.

Generated from our catalog & community — verify before relying on it.

Very small board-level lens mounts do exist below M12 S-mount, but they’re not commonly sold as easy off-the-shelf parts in small quantities.

Based on the information found, miniature mounts for small camera modules can range from M12x0.5 down to about M4.2x0.2 for very small sensors (around 1/7"). However, these parts appear to be aimed at OEM/module manufacturing, and examples may only be available with high minimum-order quantities.

The usual optics suppliers checked (such as Edmund Optics, Thorlabs, Newport, and similar vendors) do not appear to stock mounts for lenses this small as standard catalog items.

So in practice, if M12 S-mount is too large or too loose for your tolerance needs, the realistic options are:

  • source a smaller OEM-style threaded mount such as M4.2x0.2 if you can find a supplier, or
  • make a custom mount/holder for the lens.

For a one-off or prototype, a custom mount is likely the most practical route.
