ES294283U - Filters for monocromators (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Portafiltros for monochromators, that being of the type of those that incorporate a discoidal body, mounted with possibility of rotation on the chassis of the monochromator and in which the different filters are implanted, forming a circumferential and perimeter alignment, so that such in the body rotation especially facing essentially filters are susceptible, support, to remain sequential optical axis of the characterized in that such discoidal body present on each of its faces and centeredly a small recess, preferably in the form of a spherical cap, so that both recesses are left faced and located in correspondence axis of rotation of the disk, having been provided that, in addition, in the monochrome chassis, receiver of said disk, are established, also in correspondence with said imaginary axis of rotation of the disk, respective perforations, open both to the cited transverse lodging as to the outside, with its embouchure internally strangled, in each of which a steel ball plays, permanently requested towards the transverse housing by the effect of a spring, which rests in turn on a captive screw that plays in an end and threaded sector of said perforation, so that the aforementioned grub screw allows to regulate at will the pressure that the spring supplies to the ball against the filter holder disc, being this extractable, by means of a simple radial traction and with a sufficient effort to overcome the tension of the springs corresponding to the balls that frame it and that include the axis of effective rotation, said balls being retained in their housings, when removing said filter holder disc, thanks to the slight strangulation existing in the mouth of the corresponding perforations.
