Abstract: A tube lens includes a singlet and a doublet with a long front tube length between a lens stop and the tube lens. The front tube length is 1.0 to 1.5 times an effective focal length of the tube lens. The front tube length provides sufficient space for an optical platform, a folding mirror, and a telescope. The telescope rotates between a 2× mode with front and back doublets and a 1× mode with a clear aperture. The field angle of the tube lens is 4.0 degrees. Specific glass types correct the lateral color in a system for digital pathology with a white LED and a color CCD sensor. The system for digital pathology further includes an objective lens with a numerical aperture at 0.50-0.55, and a Kohler illumination system with a numerical aperture of critical illumination at 0.75-0.85 times the numerical aperture of the objective lens.

Abstract: A lens arrangement with an achromatic homogenizer and collimator for multiple LEDs. The lens arrangement combines the hemispherical emittance profiles from one or more LEDS into a collimated beam without chromatic aberration. The lens arrangement has one or more LEDs, a homogenizer, a solid lightpipe, an internal parabolic reflector, a retroreflector, and a refractor. The emittance profiles of the LEDs are distributed evenly over space and angle by multiple reflections inside a diffusely reflecting cavity of the homogenizer. The internal reflector has a numerical aperture of 1.0, which defines a hemispherical solid angle of collection within air. The retroreflector directs rays away from the LEDs. The retroreflection permits space for the electronics of high radiance LEDs. The refractor converts the retroreflector rays in a plurality of shapes. The lens is optimally designed for applications with high standards for color mixing, uniformity, and efficient conversion of electrical power into light.

Abstract: A lens system with a first group having a positive meniscus lens and a sensor. The optical distance between the front surface of the first group and the sensor can be not greater than the height of the sensor times the image F-number, which may alternatively be referred to as the working F-number. A second group can be disposed adjacent to the front focal point of the first group, and a lens-stop can be disposed adjacent to the second group. A third group can be disposed midway between the lens-stop and the object field of the first and second groups. The image F-number can be 2.8 or greater. The first group can have a doublet formed by a first lens that is plano convex and a second lens that is plano concave. The second group can have a first, plano convex lens and a second, biconvex lens forming a doublet with a third, plano concave lens.
