Double Helix Optics

3D Microscope Upgrade

Easily capture and analyse 3D images of cellular structures down to the single molecule level

  • Single or dual channel. Up to four wavelengths with multi-colour masks
  • Extends the capabilities of your microscope for nano-scale 3D imaging and sensing
  • Attaches between any widefield microscope and EMCCD or sCMOS camera, using standard C-mounts
  • Ensures pupil plane alignment to your microscope and objectives with corrective optics
  • Features a bypass mode so you can revert to 2D imaging without having to dismantle
  • Unlocks vast potential when used with other tools and techniques, including SOFI, confocal, STORM, widefield, fluorescent beads, dyes, and photoactivable proteins


Unrivalled Precision and Depth 3D Imaging & Tracking
Double Helix Optics’ SPINDLE™ gives researchers the ability to easily capture and analyse 3D images of cellular structures down to the single molecule level.

Using Double Helix Optics’ patented Light Engineering™ technology as its foundation, the SPINDLE™ can be easily installed on existing microscopes to enable advanced 3D imaging and tracking with super-resolution capabilities. Built-in bypass mode allows for easy return to non-3D experiments.

  • Patented phase mask design overcomes traditional limitations enabling 3D imaging with unparalleled depth and axial precision
  • Select from a library of masks optimised to the emission wavelength needed for your 3D experiment
  • Compatible with wide range of microscopes, objectives and cameras


Custom designed optics for precision imaging and tracking

  • Full field-of-view imaging
  • Custom optics ensure diffraction-limited performance over the full field of view of large format sensors
  • Transmission >95%
  • Built-in corrective optics to ensure pupil plane alignment to your microscope and objectives
  • Ease of install with stable alignment of x, y, and z positions of the phase mask in the relayed pupil plane


Intelligent data analysis

  • 3DTRAX™ Software, a FIJI plugin provides: 3D localisation of molecules, 3D rendering, drift correction, tracking, visualisation
  • Intuitive plots help to ensure quality data throughout the analysis process
  • Quantitative analysis
  • Ease of file export for extended analysis


Affordable and adaptable

  • Small footprint allows easy installation even in space-constrained environments
  • Input and output C-mount adapters provide easy support for commercial and custom-built microscopes and cameras
  • Highly reliable system with no moving parts. Switchable phase mask cartridges, auxiliary emission filter holders for maximum experiment flexibility
  • Modular design evolves your existing system into an advanced 3D imaging system with super-resolution capabilities


3D Double Helix super-resolution reconstruction of microtubules labeled with AlexaFluor 647. 3D with Double Helix and simulated 2D reconstructions showing z depth encoded in colour. The Double Helix 3D image captures a depth of 2.2 μm. The simulated 2D reconstruction of the same image shows 1 μm of z depth (-500 to +500 nm) and does not contain axial localisation information.​
