Concave gratings possess a number of characteristics which should make them of interest to earth-bound stellar spectroscopists. Evaluation of a number of specific spectrograph and spectrometer designs indicates that concave grating instruments can b

We propose and discuss several fabrication processes for a complex-shaped mirror, which is a fly-eye mirror, used in an extreme ultraviolet lithography (EUVL) illumination system. The mirror has a complex reflective surface consisting of many concav
oncave Collider 主要被用来计算复制与精确的碰撞效果，操作简单，只需几个点击即可完成 The Concave Collider is a component for Unity that enables complex and accurate collisions. In Unity, mesh to mesh collisions only work if at least one of the meshes is convex. The Concave Collider h
A concave two-dimensional (2D) photonic crystal waveguide (PCW) with corrugated surface is theoretically used as a focusing structure. To design this structure, a genetic algorithm is combined with the finite-difference time-domain method. For PCWs w
A method of multi-beam femtosecond laser irradiation combined with modified HF-HNO3-CH3COOH etching is used for the parallel fabrication of all-silicon plano-concave microlens arrays (MLAs). The laser beam is split by a diffractive optical element an
A new miniature spectrometer with two entrance slits is proposed to expand the spectral band. The proposed spectrometer is designed such that the two entrance slits share the same concave grating and detector array. The two slits are located at diffe
