Argo-LM Slide V2
Fluorescent calibration* slide for low magnification systems designed for the quality control of widefield microscopes (QC).
Argo-LM slides are specifically designed
for low magnification microscopes,
and especially suited for wide-field microscopes

“Both on our wide-field and confocal microscopes, it was clear to see that the brightness of the slides has been nicely improved on the new generation of slides. (…) Being a new facility, we are currently setting up some testing protocols, which we intend to do regularly to make sure our microscopes have reliable performances (…) For that, the Argolight slides are a very nice tool, because the measures are reproducible and signal intensity doesn’t change much over time. We’re thus using the slide as a standard testing target at our facility.”
Test carried out on Zeiss Widefield (Elyra 7 Lattice SIM) and ZEISS Confocal (LSM 980) with Argo-SIM V2.

“The intensity of the new slide is ~ 3-5 times brighter, depending on wavelength, compared to the 1st gen. This makes the patterns easier to find and it is easier to measure them in the orange-red and far-red wavelength regions. (…)The imaging direction is labeled on the new slide. This is nice, especially for unexperienced users, since it reduces mistakes.”

“We could test the new slide: it was indeed much brighter than our old one. In particular with white light laser systems, where each line is rather dim compared to single line lasers, that made a huge difference. We now could record images with 638 nm excitation which was not possible before.”
Test carried out on Leica Confocal (SP8), with Argo-HM V2.

“We’ve been using our previous Argolight slide to do regular Quality Control on all our microscopes. The new generation is much brighter, in our experience about 2-4x, compared to the old slides. That significantly improves QC with low NA/magnification lenses and in the red channels.”

Argolight slides are designed to do routine quality assessments and reproducibility assessments of light microscopes.
They are made to improve reproducibility of light microscopy image data through quality control management of instruments (QC).
Argo-LM slides are re-usable long lasting fluorescent slides. While intensity may fluctuate with time, we warranty that they will be fluorescent for a lifetime.
Argo-LM slides fluorescence excitation spectrum is a continuum. All slides are compatible with any excitation from 250 nm to 650 nm. Emission is also a continuum starting about 10-20 nm after excitation and ending around 800 nm.
Each Argo-LM slide contains
several fluorescent microscopic patterns
Each pattern is designed to be processed with the free companion software to detect aberrations and shift in microscopes performance. Users can catch issues before they can impact image quality and/or use the slides images to troubleshoot the image.

Content of the slide
Each Argo-LM slide contains 5 fluorescent patterns.
3D Crossing stairs
This pattern, consists of twice 21 empty cylinders embedded at different depths, like two crossing stairs, with a step of 2.5 μm and surrounded by four pillars.
4×4 Intensity gradation
This pattern consists of two layers of sixteen 100 μm- wide squares, on top of each other, having different fluorescence intensity levels following a linear evolution, organized in a 4×4 matrix.
Field of rings
This pattern consists of a matrix of 53×53 rings, separated by 50 μm, on a total field of 2600 µm × 2600 μm. The field of rings is surrounded by eight landmarks and exhibits a 25 μm long cross in its center.
This pattern consists of the letters forming the company name “Argolight”, rotated by 180° around the horizontal axis, and surrounded by a 220 µm × 50 µm frame.
