PURPOSE:To obtain high power and to compensate various aberrations excellently by allowing fix group lenses to meet specific requirements. CONSTITUTION:This objective lens consists of a positive meniscus lens having the concave surface on an object side as the 1st group, a biconvex lens as the ...
PURPOSE:To obtain the objective lens of high power with superior image forming performance by allowing an optical system which has four lens groups, i.e. cemented lens with positive refracting power, single lens with positive refracting power, and negative cemented lens successively from the object...

This illumination was achieved using an AOTF controlled by square pulses from an external function generator (Fig. 2a). The experiments were then carried out with a range of flow speeds and objective magnifications, as illustrated in Fig. 2b–e. We achieved a high flow speed of ~1 m/s...
thin specimen and high-energy electrons, the transmitted wave functionY(x,y) at the exit face of the specimen can be assumed to be composed of a forward-scattered wave. The propagation through the objective lens is the main source of nonlinear information transfer in TEM. The diffracted beams...
Both electron and heavy particle number densities, together with plasma temperature, were fitted onto the function 𝐼𝑖𝑗=𝐼𝑖𝑗(𝑁S, 𝑁e, 𝑇)Iij=Iij(NS, Ne, T) of a particular transition intensity 𝐼𝑖𝑗Iij governed by individual species abundances 𝑁𝑆NS. Each ...
One possible solution for such problems is to introduce a priori information to penalize the model, which usually involves combining the fidelity term ||Ax − y||2 and the regularization term ψ(x) into a single objective function with a regularization parameter λ, as shown in Eq. (...
