Where to download Imaris Viewer
- Go to the Imaris Viewer page on the Oxford Instruments Imaris website and choose Get Free Viewer.
- Fill in the form. When we checked on 13 November 2026 it asked for first name, last name, email, country or region, and company or organisation.
- Check your computer against the Imaris system requirements: 64-bit Windows 10 or 11, or a Mac (details in the next section).
- Install it and open the
.ims file.
The Viewer page does not state a version number. The latest Imaris release in the Imaris release notes was Imaris 11.1, dated 8 September 2026, when we checked.
Download it from Oxford Instruments rather than a third-party download site. Imaris Viewer is free, and Oxford Instruments says that, as free software, it is not supported by the Imaris support teams; questions go to its Imaris Open community.
Is there an Imaris Viewer for Mac?
Yes. Oxford Instruments lists a Mac version next to the Windows one, which makes Imaris Viewer unusual among vendor viewers. The two pages disagree on which macOS, so read both:
Neither page says which list applies to the Viewer build you receive, so check the note that comes with the download. No Linux version is listed on either page.
What Imaris Viewer does, and what needs full Imaris

How to open an IMS file with SlideScope
- Install SlideScope for Windows 10 or 11, or for macOS 14 or later (Apple silicon or Intel). The download is free, and the built-in sample library is free with every tool; opening your own images needs a subscription.
- Open the
.ims file, or drag it into the viewer.
- Step through the channels, Z planes and time points. Channels open with the colours and display ranges saved in the file, focal planes are in µm and time points in seconds.
- Check the pixel size in Details, then measure in calibrated units and add notes or regions that stay with the image.
SlideScope shows one plane at a time from the full-resolution level of the file, and compressed IMS files open too. It does not render 3D volumes, and it shows the image data, not the Surfaces, Spots or Filaments made in Imaris. Limits for every format are on the file compatibility page, and the step-by-step is in the IMS guide.
Imaris Viewer, Fiji and SlideScope compared
Imaris Viewer facts come from Oxford Instruments' own pages, checked on 13 November 2026; see the sources below.
When Imaris Viewer is the better choice
If you want to see an IMS file as a volume, rotate it, cut it with clipping planes or look at Surfaces and Spots a colleague made in Imaris, use Imaris Viewer: it is free, it is made by the company behind the format, and SlideScope does not render 3D. If you work on Linux, or want scripted analysis, Fiji reads IMS through Bio-Formats and is free. SlideScope fits when you want to open the file quickly in 2D, measure and annotate it, or when IMS is one of several formats you receive and you would rather learn one viewer.

Imaris Viewer and IMS questions
Is Imaris Viewer free?
Yes. Oxford Instruments describes Imaris Viewer as a free 3D/4D microscopy image viewer. Full Imaris is separate, paid software with its own trial.
Where can I download Imaris Viewer?
From the Imaris Viewer page on the Oxford Instruments Imaris website: choose Get Free Viewer and fill in the form, which asked for a name, email, country or region and organisation when we checked on 13 November 2026.
Is there an Imaris Viewer for Mac?
Yes, Oxford Instruments lists a Mac version. The Viewer page names Mac OS X 10.12 to 10.13, while the Imaris 11.1 system requirements list macOS 12.6, 13.3 and 14.5 and say Apple silicon is natively supported since Imaris 10.2, with an Intel version as well.
Is there an Imaris Viewer for Linux?
No Linux version is listed on the Imaris Viewer page or in the Imaris system requirements. On Linux, Fiji reads IMS files through Bio-Formats.
What can Imaris Viewer not do?
It shows and renders images. Deconvolution, detecting Surfaces, Spots, Filaments and Cells, tracking, plots, batch processing and animations are listed as features of full Imaris.
How do I open an IMS file without Imaris?
Use the free Imaris Viewer for 3D, Fiji with Bio-Formats for analysis, or SlideScope for 2D review with measurements and notes on Windows or Mac.
Is SlideScope free?
No. SlideScope is a paid app. The download and the built-in sample library are free, with every tool, and the app checks for free whether your own files open. Opening your own images needs a subscription; current prices are on the plans page.
Does SlideScope upload my images?
No. SlideScope reads IMS files from your own disk. Optional features such as AI Analysis or shared links are separate, and only run when you choose to use them.
