The pocket microscope pulls back to show more of what you want to see.

The iMicro XL15 takes a slightly different approach to smartphone microscopy. Built by the team behind the iMicro Q3p that we covered in 2024, it weighs just 1.2g (0.04oz), but it’s a very deliberate departure from that model’s headline-grabbing 1,200x magnification.

Its magnification is much more modest, but what you get is a much wider field of view and around 21mm (0.8 in) of working distance between lens and subject.

Extra breathing room is the key point here. Instead of having to force the optics directly against a flat specimen, the XL15 leaves enough room to inspect more awkward three-dimensional subjects, while still giving you a useful close-up view.

That extra working distance allows you to view circuit boards, plant and insect structures, or manipulate small components while keeping them under the lens. The 10mm field of view also captures broader context rather than isolating a small fragment.

iMicro says resolution is around 8µm when used with a wide-angle camera, which improves to around 3µm with a telephoto camera, although real-world results will also largely depend on the phone, focus and lighting settings you’re using.

Lighting is another important part of the XL15’s tone. Its own lighting module is removable and has a rechargeable battery. Instead of relying on a fixed light source, you can position it independently for direct white lighting, colored light, low-angle side lighting, or UV light. Side lighting is particularly useful as it helps reveal surface texture, edges and relief. Meanwhile, UV rays could expose fluorescence in certain materials. However, iMicro notes that this feature is purely exploratory; It is not specialized fluorescence microscopy. The slim PP carrying case can also function as a simple softbox.

The XL15 connects to compatible phones and tablets using a reusable nano-suction cup, so you won’t need a dedicated case or adapter. It works best in smooth, non-porous camera environments, and can be used handheld. For more precise adjustments and more stable images, the included FS-5 focus bracket is probably your best option. A μRuler M stage micrometer provides a scale reference. The XL15 works with a phone’s regular camera app, while the optional i-SEEING app adds calibrated scale bars and measurement tools.

Kickstarter pledge levels start at CAD 84 (around $60) for the Super Early Bird tier. The kit includes the XL15 lens, a detachable light, a focus holder, μRuler M, the i-SEEING app, and a carrying case.

All crowdfunding campaigns carry an element of risk, but this isn’t the first time the brand has launched a dozen Kickstarters into its trophy case. This latest campaign runs until December 19 and, at the time of writing, has raised more than five times its funding goal. If everything goes as planned, shipping is estimated to begin from April 2027.

It will not replace a proper laboratory microscope anytime soon. But for about $60 and weighing barely more than a clip, the XL15 offers smartphone microscopy something its high-magnification predecessors lacked: handy space to work with.
