Description
The Argo-POWERHM is specifically designed to assess and follow the performance of fluorescence-based imaging systems, such as wide-field, confocal, spinning disk and other types of microscopes, with high magnification (HM) objectives.
This product is composed of a calibrated optical power meter, an Argo-HM patterned glass and Daybook 3, their companion image analysis software.
The calibrated optical power meter is designed to measure the optical power of light sources at the sample plane in microscopy setups. The Argo-HM glass is a special glass substrate with different fluorescent patterns embedded inside. Daybook software allows to analyze and extract data (maps, graphs and metrics) from images of the patterns, in order to control significant parameters of your fluorescence imaging system.
Slide Contents:
The Argo-POWERHM contains slide contains 10 fluorescent patterns.
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 B – Field of rings. This pattern consists in a matrix of 39× 39 rings, separated by 15 μm, on a total field of 600 × 600 μm². The field of rings is surrounded by eight landmarks, and exhibits a 7.5 μm long cross in its center.
Pattern C – 4×4 Intensity. This pattern consists in sixteen 8.5 μm-wide squares having different fluorescence intensity levels following a linear evolution, organized in a 4×4 matrix.
Pattern D – 2×16 Intensity. This pattern consists in twice sixteen 22.5 μm × 1.5 μm rectangles having different fluorescence intensity levels following a linear evolution, organized in a 2×16 matrix.
Pattern E – Gradually spaced lines. This pattern consists in pairs of 50 μm-long lines which spacing gradually increases, from 100 to 700 nm, with a step of 50 nm. Four sets of lines are present: one vertical, one horizontal, and two oriented at + and – 45°.
Pattern F – Matrix of crosses.This pattern consists in a matrix of 6 × 6 crosses, having a length of 5 μm. The crosses are composed of vertical lines that are in the same plane, and by horizontal lines, going gradually deeper within the glass. The spacing between the vertical and horizontal lines gradually increases, from 0 to 3.5 μm, with a step of 100 nm.
Pattern G – Meridians of a sphere. This pattern consists in three circles of diameter 50 μm in different orthogonal planes, featuring the meridians of a sphere.
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 I – 3D Crossing stairs. This pattern consists in empty cylinders embedded at different depths, like two crossing stairs, surrounded by four pillars. There are four stairs in the slide, with varying steps: 1, 0.75, 0.5 and 0.25 μm.
Pattern J – Logo. This pattern consists in letters forming the company name “Argolight”, and surrounded by a 220 μm × 50 μm frame.
