Abstract: To eliminate influence of undesirable light component from an object when measuring optical characteristics such as shape and wavefront aberration of the object, light from light source (101) is separated by polarization beam splitter (103) into measuring light (L1) that irradiates and travels via the object (108) and is condensed on image plane (P) through microlenses (114a) of microlens array (114), and reference light (L2) that does not irradiate the object and is guided to the image plane by reference light optical system (109). A computer (113) acquires picked-up images sequentially from CCD image sensor (116) arranged on the image plane while changing optical path length of the reference light by movable stage (117), extracts interference light spots generated through interference between signal light component and the reference light from the picked-up images, calculates positions of the interference light spots, and calculates deviation amounts of positions from predetermined reference positions.

Abstract: The present invention provides a metal powder composed of tantalum or niobium that achieves both sinterability and fluidity and the manufacturing method thereof. The present invention also provides a tantalum or niobium powder that enables the manufacturing of an anode for a solid electrolytic capacitor in which holes are formed for a conductive polymer-containing solution to pass through, without using a hole molding material or pore forming material. Furthermore, the present invention provides an anode for a solid electrolytic capacitor that enables the manufacturing of a high-volume and low ESR solid electrolytic capacitor. The present invention further provides a manufacturing method of a metal powder that allows the manufacturing of a metal powder of a given diameter range from a raw powder at high yield, without requiring a lot of work and time.

Abstract: A process and system for producing tantalum or other valve metal particles is provided comprising forming tantalum particles in a reduction process carried out in a reactor vessel, and using a siphon to transfer fine tantalum particles out of the reaction mixture to a recovery vessel. This particle transfer can occur while the reaction mixture is agitated. The tantalum particles can be automatically withdrawn when the reaction mixture has a depth level greater than the fluid level of the tantalum fine particle recovery vessel, and outflow automatically stops when the fluid levels of the reactor and particle recovery vessel equilibrate. Tantalum or other valve metal powders made by the processes, and capacitors made with valve metal powders are also provided.
