Achromatic Visible To Far Infrared Objective Lens
US Patent:
2011005, Mar 3, 2011
Filed:
Aug 25, 2010
Appl. No.:
12/862906
Inventors:
Christopher Alexay - Keene NH, US
Assignee:
StingRay Optics, LLC - Keene NH
International Classification:
G02B 13/14
US Classification:
359356
Abstract:
Disclosed herein are lens systems that are capable of imaging in the visible spectrum to the far infrared spectrum. The lens systems are formed from optical crystals with different and substantially parallel partial dispersion characteristics.
Wide Band Achromatic Visible To Near-Infrared Lens Design
US Patent:
2008022, Sep 18, 2008
Filed:
Mar 12, 2007
Appl. No.:
11/684723
Inventors:
Christopher Carl Alexay - Keene NH, US
International Classification:
G02B 13/18, G02B 9/02
US Classification:
359718, 359796
Abstract:
A lens design comprising a positive lens made of barium fluoride crystal material and a negative lens element made of glass with dispersive properties common to the family of Schott type materials enabling an object to be imaged with superior chromatic aberration correction in the spectral range extending from the visible to the near-infrared region of the electromagnetic spectrum. The achromatic lens design as described has negligible residual and higher order chromatic aberration throughout the visible, the near-infrared or simultaneously both the visible and near-infrared regions of the electromagnetic spectrum.
