Efficient and flexible Focused Ion Beam micromachining of Solid Immersion Lenses in various bulk semiconductor materials – An adaptive calibration algorithm

Focused Ion Beam (FIB) micromachining of Solid Immersion Lenses (SILs) in substrate material offers optical analysis solutions for current and future technologies without the limitations of external SIL systems. This work presents an efficient single iteration calibration algorithm. This algorithm enables the implementation of FIB created SILs using a variety of substrate materials, process chemistries and most importantly different SIL shapes to match sample thicknesses. The successful application on silicon and silicon carbide is presented by creating a 50 μm wide refractive lens segment with a radius of curvature of 60 μm. Laser scanning microscope images of a silicon sample demonstrate the optical benefit with a measured resolution of 274 nm.

Study of the fabrication of infrared-transparent dielectric aspheric deposits by continuous-wave laser deposition

The fabrication of dielectric aspheric deposits with optical refractive functionality by a continuous-wave laser deposition technique is reported for the particular case of an amorphous As-S alloy. The influence of both the laser power and fabrication times in the deposit thickness profile is studied from the measurements performed by a mechanical profilometer. The use of press-powder tablets as starting material have been found to have a significant effect in the deposition efficiency, and indications of a transition from a discrete to a continuous nature of the target, have also been observed. A notable reproducibility has been found both in the material stoichiometry and thickness profiles. The optical function of the fabricated refractive aspheric deposits has been measured to be similar to one performed by axicon lenses.     

Study of the growth of infrared-transparent non-spheric layer lenses by continuous-wave laser deposition

The fabrication of non-spheric microns-thick layer lenses by continuous-wave laser deposition has been monitored by using an interferometric method. An infrared-transparent amorphous chalcogenide alloy has been used as base material. Results evidence the thermodynamic nature of this laser-assisted deposition process, with two distinct stages occurring in the deposition rates, namely, a first induction stage with thickness increasing at non-constant rate, and a second steady-state stage with thickness increasing at constant rate. The deposition process has been shown to be reproducible and it allows the tailoring of the thickness profile for promising fabrication of non-spheric layer lenses and free-form optics.     

Paraboloid–aspheric lenses free of spherical aberration

A method to design singlet paraboloid-aspheric lenses free of all orders of spherical aberration with maximum aperture is described. This work includes all parametric formulas to describe paraboloid-aspheric or aspheric-paraboloid lenses for any finite conjugated planes. It also includes the Schwarzchilds approximations (which can be used to calculate one rigorous propagation of light waves in physic optics) to design convex paraboloid-aspheric lenses for imaging an object at infinity, with explicit formulas to calculate thicknesses easily. The results were verified with software through ray tracing.     

人眼消色差：色视差问题

如果眼睛不与消色差系统的光轴共轴，那么校正人眼聚焦色差将导致我们所不期望的色视差。用几何光学方法可以证明视差量大约与眼睛的不共轴量成正比，其比例常数与眼睛的色差相同。饮用两种市场上可得到的消色差透镜，通过色差试验证实了此推测。基于这些结果，可以计算出，该消色差透镜给眼睛的复色调制传递函数提供的改进量，将由于透镜和眼睛之间的大约0．4mm的不共轴性抵消。对比灵敏度的心理物理实验已证实了我什1的推测：不关轴量的进一步增大特严重降低已消色差眼睛的成像质量。
