摘要： There is provided an optical imaging device for splitting an initial image into images with different optical characteristics, wherein the device comprises a plurality of beamsplitters and at least first and second reflectors arranged to create multiple images adjustably separable in two orthogonal directions, characterised in that the first reflector is rotatable about a first axis and the second reflector is rotatable about a second axis, the second axis orthogonal to the first axis. The beamsplitters are located in a first optical layer to create multiple optical pathways directed substantially orthogonally from the first optical layer to a second spaced apart optical layer. Each reflector can be moved translationally relative to its rotational axis.

摘要： There is provided an optical arrangement comprising a digital micromirror device having a plurality of individually adjustable mirrors, a mirror pair formed from a convex mirror and a concave mirror having a common centre of curvature, the concave mirror having a greater radius than the convex mirror, characterised in that a collimated space is immediately adjacent the convex mirror, and the concave mirror is offset from the convex mirror so as to be capable of forming an image at an effective focal length of the mirror pair. The convex mirror and the concave mirror have radii substantially in the proportion 2.5:1, the concave mirror having the greater radius. A confocal microscope using such an arrangement is also provided.

摘要： There is provided a microscope focus control system comprising an illumination source (70) and a polarisation-sensitive detector (66) positioned to receive a reflected beam (40) from an interface (54) having a reference refractive index and configured to detect polarisation components of the reflected beam (40). An elongate aperture (72) is disposed proximal the illumination source (70) to generate a rectangular beam (74) to impinge on the interface (54) and a second aperture (106) is located at a position corresponding to an unfocused region of the reflected beam (40) from the interface (54) so as to direct unfocused reflected light onto the polarisation-sensitive detector (66). Changes in polarisation components of the reflected beam are used to measure of change in position of the interface (54) relative to the objective (50). The reflected beam (40) is generated by Fresnel reflection.
