Abstract: An interferometer modulator (10) has a housing (12) that encloses a moving mirror attached to a mirror arm which is suspended by links (34, 36) from the housing (12). The links (34, 36) are attached to the mirror arm at swinging pivots and are attached to the housing (12) at fixed pivots (46, 48). One of the fixed pivots (46) is mounted within an adjustable block (68) the position of which may be adjusted by the turning of adjust screws (82, 76).
Turning of one of the adjust screws (82) adjusts the distance between the fixed pivots (46, 48) to match the distance of the swinging pivots (42, 44), thus correcting for vertical tilt. Turning of the second of the adjust screws (76) compensates for any angular differences that would prevent the links (34, 36) from moving in the same plane of motion, thus correcting for horizontal tilt.

Abstract: A mirror system for infrared spectrometers and the like includes a baseplate having a flat top surface which defines a reference plane, with reference locators, such as holes, in the baseplate defining the desired positions of the intersections of the center lines of the beam paths above the baseplate. Alignment locator holes are also formed in the baseplate. Mirrors are formed of a unitary mirror body in which a mirror surface -- flat, concave, or convex -- is formed such as by diamond turning. Each of the mirrors has a reference locator on its bottom surface which lies directly underneath the surface vertex of the concave or convex mirror surface or beneath the center of the plane of a flat mirror. Each mirror also has an alignment locator on its bottom surface spaced away from the reference locator. The reference locator and alignment locator may comprise pins which extend from the bottom surface of the mirrors. The mirrors are mounted to the baseplate by engaging the pins on the bottom surface of the mirrors with the corresponding reference locator and alignment locator holes in the baseplate. When the mirrors are mounted to the baseplate in this manner, all of the mirrors are properly aligned without further adjustment, thereby determining all of the beampaths and the focal points of the beams in the optical system.
