Lens makers formula||Magnification||Thin lens combination||Examples on lens maker's formula View Solution A thin convex lens of focal length 'f' is put on a plane mirror as shown in the figure . When an object is kept at a distance 'a' from the lens - mirror combination , its image...
1.What is the lens maker formula and why is it called so? The lens maker formula is a relation between the focal length, the refractive index of the constituent material, and the radii of curvature of the spherical surfaces of a lens. The refractive power (inverse of focal length) can b...
And with a very favourable priceperformance ratio, coupled to innovative designs, these makers made substantial inroads in the traditional markets. On the optical front, the Leitz designs, while still first class, ran into stiff competition from several Japanese and German companies, whose design ...
It's a completely new lens, rather than a revision of Sigma's existing 50mm F1.4 EX DG HSM, with an unusually complex optical formula for its type (13 elements in 8 groups). It's also rather large, with a strong family resemblance to the excellent 35mm F1.4 DG HSM. Overall this ...
Since its first iteration in 2022, the Fintech Islands Conference is fast becoming one of the ‘must-attend’ conferences in the Caribbean region for persons with an interest in fintech, allowing for a rich exchange of insights and ideas among industry gurus, regulators and policy makers from ...
Lens formula1 / v – 1 / u = 1 / fwhere ‘u’ is the distance of the object from the optical centre of the lens‘v’ is the distance of the image from the optical centre while ‘f’ is the focal length, the distance between the optical centre and the focus of the lens....
From Lens Makers formula, 1f=−(μ−1)(1R1–1R2)For equi-convex lens,R1=+R,R2=−R⇒1f=(μ−1)(2R)⇒f=R2(μ−1) If f<R then, 2(μ−1)<1⇒(μ−1)<12⇒(μ−1)<0.5⇒μ<1.5Focal length of a convex lens is positive. Show More ...

it has been pointed out that media makers encounter the problem of an increase in manufacturing costs including plant and equipment investment. Thus, an HD standard has been created as coexisting with a BD standard, and the HD standard is based on the condition that the HD can be manufactured...
