  • Optical magnifier
    Patent number: 10067334
    Abstract: An optical magnifier suitable for viewing microdisplay panels and other optical fields and providing a wide field of view with minimal aberrations across the field over a large pupil with long eye-relief. The magnifier comprises six lens elements formed without the use of expensive very high dispersion glass. The lens surfaces are spherical and/or flat thereby simplifying lens fabrication. A similar magnifier with fewer lens elements configured to view a concave image surface is also disclosed.

  • Macro accessory for telescope
    Patent number: 9904032
    Abstract: An optical macro adaptor assembly comprising two or more lens components arranged successively along the optical axis thereof, configured to be mounted in front of the objective lens of a telescope, and acting to reduce the minimum focus distance of the telescope to permit the telescope to be used in environments requiring a close focus. The optical macro assembly can be a Galilean-type optical system of approximately unit magnification with adjustable spacing between the lens elements to allow for focusing.
