Abstract: The present invention relates to optical imaging systems which are able to provide increased depth of field to microscope devices, motion-picture cameras, and still photographic cameras. Optical systems described herein are able to provide the increased depth of field while maintaining wide field of view and reducing spherical aberration and distortion. Optical systems described herein are also able to be used with standard film and digital sensor formats, and are able to be attached to, or integrated with, photographic and motion-picture cameras, including currently existing cameras.

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: The present invention provides a complex modular afocal variator in which a modular afocal variator is supplemented with additional optics to form a more complex, but still modular afocal variator system, that can impart internal focusing as well as active spherical and chromatic aberration corrective improvement.

Abstract: The present invention provides optical systems containing an afocal variator able to impart focus means to the optical system, as well as essentially constant magnification throughout the focal translation. The present application teaches a specific formula or set of spacing requirements for the positioning of the afocal variator that can be used with any afocal variator optical lens system comprised of various lens combinations. Provided that the formula for spacing the afocal variator within the optical system is utilized, the afocal variator acts not only to focus the optical system but maintains substantially constant magnification during the translation of focus.

Abstract: An afocal optical module simulator (aoms) for use in conjunction with one or two other optical modules to simulate an afocal variator optical system. The aoms is comprised of an optical module having a front and a rear end, and includes a movable negative lens. The front end of the aoms includes a mechanism for securing a front optical module which may include as its rear most element a positive lens system which will be located juxtaposed to, but spaced from, the movable negative lens within the aoms. Similarly, the rear end of the aoms includes a mechanism for securing a rear optical module, which includes as its front most element a positive lens system which will be located juxtaposed to, but spaced from, the movable negative lens within the aoms.

Abstract: In this system a module carries an afocal variator optical system, and to which module a front partially-obscured reflecting telescopical system and a rear system module can be substantially permanently connected in combination to vary the actual focal length of the front partially-obscured reflecting telescopical system in conjunction with a rear system module without the need to physically change the length dimension of any system, or without the need to change the mirror position or positions of the front module. A partially-obscured reflecting telescopical system is defined as any selected from the group Newtonian, Cassegrain, Ritchey-Chretien, Gregorian and any of their derivatives, including catadioptric derivatives, such as Maksutov and Schmidt types, in which the incoming light is obscured by a central disk with reflecting obverse side, diagonal mirror or pickoff mirror essentially on-axis to the incoming light.

Abstract: The combination in optical series of a microscope objective lens system with a first positive lens system, and a focusing module, all in combination with one another and with such other components as are required to provide a microscope image, allows the user of such a microscope, to continuously alter the active focal relationships of the microscope by continuously varying the afocal variator and the distance of the microscope objective lens system from the object which is undergoing examination, and all without the need to physically change the length dimension of the microscope system, and without the need to change the positions of any of the lenses outside of the afocal variator, and without the need to change the microscope objective lens. The focusing module includes, a front negative lens system, an afocal variator optical system, and a rear positive optical system. The afocal variator optical system includes in optical series a front positive lens, a negative lens, and a rear positive lens.

Abstract: A modular optical system is provided in which a central element which carries an afocal variator optical system is provided, and to which central element both a front optical system and a rear optical system can be substantially permanently connected in optical series in combination. The modular optical system has the ability to vary the actual focal length of the front optical system in conjunction with the rear optical system without the need to physically change the length dimension or the lens position or the lenses of the front optical system. The afocal variator optical system includes in optical series a first positive lens, a negative lens, and a second positive lens.
