Argo-POWERLM Slide V2

Fluorescent calibration slide with integrated power meter for high magnification systems, designed for the quality control of wide field microscopes (QC).

The LM core of the POWERLM slides are specifically designed designed for low magnification microscopes, and especially suited for widefield microscopes.

Example of suited systems

LAS X line

LS line

Revolve line

AxioObserver lines

Eclipse line

BX lines

The Argo-POWER line of products integrates a compact yet sensitive power sensor. No need to modify your setup. Its shape and thinness make it fit adequately inside your microscope.

No more “Will 20% laser power kill my cells”. Using Daybook, our companion software, you can measure live power, record timelapses and trace input vs on-sample power graph. The software can generate ready-to-print reports based on your results.

Track the aging of your light sources with a reliable device. Argo-POWER sensors are calibrated and traceable to National French metrology institute (LNE) standards. Each comes with a certificate. Re-certification services are available.

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-POWERLM 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-POWERLM glass core 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-POWERLM glass core 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-POWERLM slide contains 5 fluorescent patterns.

3D Crossing stairs

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.

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.

Repositionning crosses

The repositioning crosses are 40 μm long.
