Abstract:
According to some embodiments a method of assembling an optical system comprises steps of: measuring retardance profiles of a plurality of optical elements, relatively positioning the optical elements in relative orientations that enhance complementarity between the retardance profiles of the optical elements, and securing the combinations of relatively oriented optical elements together, to control or minimize the combined retardance of the stacked optical elements.
Abstract:
A lens assembly including a lens; a light absorber that does not transmit light with wavelengths from greater than or equal to about 250 nm to less than or equal to about 400 nm; a lens holder; and an adhesive configure to adhere the lens to the lens holder. The light absorber is positioned such that light having a wavelength from greater than or equal to about 190 nm to less than or equal to about 500 nm is not incident to the adhesive. A method including applying a light absorber, which does not transmit light with wavelengths from greater than or equal to about 190 nm to less than or equal to about 500 nm, to a lens; and configuring the light absorber and the adhesive so that the absorbed light is not incident to the adhesive.
Abstract:
An optical device includes a support structure configured to retain an optical element using a cured adhesive composition that is disposed between a surface of the support structure and a surface of the optical element, wherein a structured optical particulate material is dispersed throughout the cured adhesive. The structured optical particulate material redirects curing radiation via a scattering mechanism to facilitate curing of portions of the adhesive compositions that cannot be directly exposed to the radiation, thereby facilitating rapid and more thorough curing than could otherwise be achieved without the structured optical particulate material.
Abstract:
A compound optical assembly is constructed from a plurality of stacking elements for spacing, aligning, and retaining optical elements within the assembly. Stacking faces of the stacking elements are measured and low-order surface errors are extracted, represented by mathematical approximations having a primary angular frequency. The stacking elements including the optic holders are relatively oriented to promote complementarity between the low-order surface errors of mating stacking faces.
