Two panels in the sides of the box slid smoothly up and down, so that a pair of hands might be inserted, and the square lens, attached to a system of rods and screws, could be raised and lowered.
The results are expressed as number of positive cells per millimetre squared when a ×10 objective lens was used.
With the aid of the court carpenter, for whom he drew up a plan, the maker of miniatures constructed a teakwood box with a sloping top, in which was set a square magnifying lens.
The optics consists of a primary and a secondary optics: the former is a PMMA square Fresnel lens (75 mm – side) with constant pitch; the latter is a refractive optics (RTP) realized with dielectric material, that i) improves the light homogeneity on the cell area, ii) reduces the negative effects of the sun-tracking misalignment and iii) increases the concentration ratio.
First, we plotted the square of lens diameter against the product of eye diameter and axial length (OPTmorph1, Figure 2b).
On the basis of these loadings species with high optical ratio, i.e., the ratio of the square of lens diameter and the product of eye diameter and axial length should plot in the bottom right quadrant of morphospace.
At the time of the measurement, squared grids will be set in an ocular lens, and thereafter, the length of the cortex will be measured.
In confocal imaging for example, the illumination and detection is done by the same lens, hence in a first approximation the PSF can be squared [19].
In this work, we employed the square micro-lens array (SMLA) with ideal aspect ratio of 100%, to realize high performance integral imaging 3D display systems.
To accommodate the large size of the SLM (20mm square), the lenses were chosen to slightly reduce the image of the SLM at the pupil plane of the objective using two IR doublets f = 200mm and f = 160mm respectively (Linos Photonics, QiOptic).
