Check the lateral resolution of your super-resolution system


Argolight slides are designed to routinely check the stability of the characteristics of your systems.


Argo-Check Resolution  is a re-usable stable fluorescence slide for assessing and monitoring fluorescence-based imaging systems. This slide is specifically designed for super-resolution system (confocal and SIM).

The Argo-Check Resolution slide contains mainly seven fluorescent microscopic  patterns designed to mesure the lateral resolution of your imaging system.

You can check the lateral resolution from 0 to 390nm.

A complete solution

All Argolight slides come with DAYBOOK software (Free access). It will help you to standardize the analysis of your images and compare your results with your colleagues or between systems.


Data is stored in clear common formats and is clearly time-stamped. You can access past data, share it or store copies on your servers.

Fluorescence properties

Their intensity and spectrum are stable for over 3 years.  The analysis of pattern images can be simplified using Argolight software solutions. The slides are compatible with excitation from 350 nm to 650 nm (Fluorescence excitation over 550 nm requires sensitive sensors). More about slides stability


Strenghts of the solution

  • Ensure reliability and stability of an imaging system – obtain coherent measurements comparable over several years (including fluorescence quantities).
  • Set-up and maintain quality management at a low cost for fluorescence measurements.
  • Simplicity : No need for refrigerated storage, no consumable to add.
  • Ruggedness : Withstands fall from 2m height thanks to its metallic enclosure.
  • Compatibility : Works with oil immersion, dry objectives and water immersion objectives (more about water immersion).
  • Cost : Replaces consumable tools and increases monitoring frequency.

Content of the slide

The Argo-Check Resolution contains:

Pattern A – Target. This pattern consists in concentric circles with increasing radii from 25 μm to 300 μm with a step of 25 μm, plus an extra circle with a radius of 12.5 μm, featuring a target.

Pattern E – Gradually spaced lines. This pattern consists in pairs of 36 μm-long lines which spacing gradually increases, from 0 to 390 nm, with a step of 30 nm. Four sets of lines are present: one vertical, one horizontal, and two oriented at + and – 45°

Pattern H – Repositioning crosses. The repositioning crosses are 20 μm long and are positioned 500 μm from one to another in the X direction, the Y direction, or both.

Pattern J – Logo. This pattern consists in letters forming the company name “Argolight”, and surrounded by a 220 μm × 50 μm frame.
