A method of manufacturing an led lighting arrangement, comprises: receiving an optical component having a diffusing material that is light diffusive and at least one photoluminescent material that is excitable by light of a first wavelength range and which emits light of a second wavelength range; receiving an led assembly that is operable to generate the light of the first wavelength range and mounting the optical component to the led assembly to form the led lighting arrangement. The optical component having the diffusing and photoluminescent materials is mass produced separately from the led assembly and can be selected such that light generated by the optical component combined with the light generated by the led assembly corresponds to light of a selected color.

Projection-type charged particle optical system and imaging mass spectrometry apparatus


Provided is a projection-type charged particle optical system in which a projection magnification can be changed while a decrease in the accuracy in measuring a mass-to-charge ratio is being suppressed. A projection-type charged particle optical system according to the present invention includes a first electrode disposed so as to face a sample and having an opening formed therein for allowing a charged particle to pass, a second electrode disposed on a side of the first electrode opposite to where the sample is disposed and having an opening formed therein for allowing the charged particle to pass, and a flight-tube electrode disposed such that the charged particle that has been emitted from the sample and has passed through the second electrode enters the flight-tube electrode and being configured to form a substantially equipotential space thereinside.
