For example, in an optical device such as a telescope, a binocular or a microscope, an ocular lens is used to further enlarge and view a real image formed by an objective lens. It is demanded that such an ocular lens have a sufficient eye relief (the on-axis spacing between the outermo...
The system includes an objective lens system of positive refractive power, an erecting lens system and an ocular lens system of positive refractive power. The erecting lens system inverts the back-to-front image from the objective lens system. The erecting lens system comprises several reflection ...
The objective limitations and ethical issues inherent in human studies have made animal models of uveitis an invaluable tool for dissecting the basic mechanisms in pathogenesis of the disease. As no animal model can reproduce the full complexity of the human disease, it is necessary to develop and...
PROBLEM TO BE SOLVED: To provide an ocular constituted so that coma is excellently corrected while excellently keeping astigmatism and distorsion aberration. ;SOLUTION: This ocular is constituted of a 1st lens being a convex lens whose powerful concave surface is faced to an objective side and a...
The concentrations were 10.68 ± 1.87 μM for Ap4A and 12.45 ± 0.20 μM for Ap5A. From these results, the authors proposed these molecules as an objective biomarker for scoring the severity of dry eye. In 2010, a research paper was published about the diadenosine polyphosphate concentrations...
