Abstract:
Dual-pupil, dual spectral band wide field-of-view re-imaged refractive optical imaging systems. In one example an optical imaging system includes a dual-band front objective lens group configured to receive electromagnetic radiation over the field-of-view of the optical imaging system, to form a first pupil, and to direct the electromagnetic radiation through the first pupil, the electromagnetic radiation including first and second non-overlapping spectral bands, and the field-of-view spanning at least 45° x 45°, and a re-imaging refractive optical sub-system configured to receive the electromagnetic radiation via the first pupil, to form at least one intermediate image plane, and to focus the electromagnetic radiation via at least one second pupil onto at least one final image plane to form a first image from the first spectral band and a second image from the second spectral band. A beam deflector can be positioned proximate the first pupil to expand the field of view.

Abstract:
The present invention provides microscopes and optical devices able to provide improved spherical aberration correction through the combined use a first optical system which comprises a common moveable or deformable rear lens system which forms part of the microscope objective in conjunction with a semi-objective lens system, and a second optical system which comprises a telescopic focusing system. Deforming, moving or repositioning one or more lenses of the common moveable or deformable rear lens system in the first optical system is able to act primarily on the anterior Gauss particulars (or the front conjugate) of the objective, while the telescopic focusing system of the second optical system is able to act on both the anterior and posterior Gauss particulars (or the front and rear conjugates). Adjustment of both optical systems in combination with one another allows for the formation of an improved image with enhanced spherical aberration correction.
Abstract:
A projection apparatus has a spatial light modulator to modulate illumination from a laser light source. A base projection lens has, from its long conjugate side to its short conjugate side, a first lens group with negative focal length and with a first lens element that has a negative focal length and a second lens element of positive focal length, a second lens group of negative focal length and spaced apart from the first lens group and having one or more cemented lens elements, and a third lens group spaced apart from the second lens group and having a lens with a positive focal length. The base projection lens has a first field of view and is telecentric in its short conjugate. An afocal attachment to the base projection lens alters the first field of view by the same amount in both of two orthogonal directions.

Abstract:
A small format factor camera system for mobile devices that provides improved image quality when using accessory lenses. The system may detect an accessory lens attached to the camera, either via sensing technology or by analyzing captured images. The system may analyze image data to determine current alignment (e.g., optical axis alignment, spacing, and/or tilt) of the accessory lens relative to the camera lens, and may shift the camera lens on one or more axes using a mechanical or optical actuator, for example to align the camera lens optical axis with the accessory lens optical axis. The system may also determine optical characteristics of the accessory lens, either via sensing technology or by analyzing captured images, and may apply one or more image processing functions to images captured using the accessory lens according to the determined optical characteristics of the accessory lens.
