Historical development of FINCH from the beginning to single-shot 3D confocal imaging beyond optical resolution
Product: Argo-SIM

They cited us within the framework of a review chronicling the 15-year development effort of Fresnel incoherent correlation holography (FINCH) since its first description to its current 3D current microscopic wide-field or confocal imaging. The gradually spaced lines of an Argo-SIM slide were used as a ground truth to demonstrate resolution improvement down to about 100 nm.
Citation page B130:
To further set FINCH in context compared to other super-resolution microscopy systems, we also have imaged the Argolight SIM resolution test standard. The pattern of interest for this sample is a series of fluorescent lines embedded in a glass matrix. The lines are arranged in a series, with pairs of lines separated from each other by progressively less distance in increments of 30 nm, from 390 nm separation to 0 nm separation, to serve as a test for two-point resolution that can be compared across different instruments. We imaged this sample in the instrument described in at a 520 nm emission wavelength with a 60× 1.49 NA oil immersion objective without the confocal disk. The resulting image is shown in Fig. 15, comparing a wide-field image to the FINCH image. The images and plots show that the line pairs are resolved at 210–240 nm in the wide-field image, though they are not resolved to the full Rayleigh criterion. However, in the FINCH image, the line pairs with 120 nm or more separation are well resolved by the Rayleigh criterion. The line pair at 90 nm separation is nearly Rayleigh-resolved and is as well resolved as the wide-field image of the 300-nm separated line pair. This result, on a challenging sample, was obtained with a single snapshot confirming the ability of FINCH as an effective (as well as simple and inexpensive) super-resolution technique.

They cited us within the framework of a study dealing with a new deconvolution algorithm, called sparse structured illumination microscopy (Sparse-SIM). This method allows to increase the resolution of super resolution microscopes nearly twofold, based on a priori knowledge about the sparsity and continuity of biological structures. The gradually spaced lines of an Argo-SIM slide, consisting of fluorescing double line pairs, was used as a ground truth to validate the increase in resolution.
Citation page 3:
Similarly, one obscure line in the commercial Argo-SIM slide under 2D-SIM could be resolved as two parallel lines 60 nm apart after sparse deconvolution only. This resolution enhancement was maintained in processing variable SNR images captured under different conditions but failed at extremely low SNRs, recapitulating previous experiments with the synthetic image.

To validate the precision control of projection depth of EF, we performed several experiments with the Argolight SIM test slides. The Argolight test slides series contains optical band gaps that mimic the behavior of fluorophores. Each test slide contains several known geometrical structures that are rendered very precisely. It is commonly used by optical microscopists to evaluate various performance parameters of the systems of interest, such as illumination homogeneity and the resolution limit. Patterns I and G of the Argolight SIM slide were chosen as quantitative tests for the depth resolution because they feature high-resolution structures in the Z-direction.

They cited us within the framework of a study dealing with the navigation of the challenges in the application of super-resolution microscopy, in particular, structured illumination microscopy (SIM). The gradually spaced lines pattern of an Argo-SIM slide was used to show how low signal-to-noise ratio acquisition conditions in SIM lead to reconstruction artifacts in the image.
Citation:
Optimization of super resolution microscopy is aided by standards for characterizing instrument performance and methods for assessing image quality. Useful standards include well-characterized biological structures (such as microtubules), nuclear pores, clathrin-coated pits, centrioles or synaptonemal complexes, DNA-origami rulers, and micropatterned slides (Argolight).

The so far only commercially available product which addresses to fulfil the requirements mentioned above (e.g., the production is standardized, and the long-term stability of fluorescence is guaranteed for five years) is the Argolight calibration slide.

To overcome the various limitations of approaches that use beads or DNA origami, in recent years techniques have been developed to create slides imprinted with defined patterns for system calibration. For example, Argolight uses a laser to induce into glass substrates fluorescent materials that are stable and have a broadband emission spectrum. An example of an Argolight slide contains different fluorescent patterns in two and three dimensions, the elementary structure of which is an empty cylinder with a diameter of about 0.7 μm.
