  • Optical devices and methods
    Patent number: 7076132
    Abstract: A fiber optic device comprises an optical lens element having a focal length greater than 2 mm, and an optical signal source or receiver mounted at the focal plane of the optical lens element and operative to communicate optical signals with a selectively transparent interference filter through the optical lens element. Methods for the production and use of the fiber optic devices are also disclosed.
    Type: Grant
    Filed: April 18, 2003
    Date of Patent: July 11, 2006
    Assignee: Bookham (US) Inc.
    Inventors: Richard James Ryall, Michael A. Scobey, Loren F. Stokes

  • Fluorescence station for biological sample testing machine
    Patent number: 5925884
    Abstract: A sample card transport station moves a test sample card from an incubation station for the card to a transmittance and fluorescence optical station in a sample testing machine. The sample card transport station has a drive belt and an associated stepper motor. The belt supports the card from one side of the card. A ledge having a card slot is disposed above the belt. The card is snugly received within the card slot, and supported from below by the drive belt and rollers for the belt. When the motor turns the belt, the belt grips the card and slide the card along the slot to the optical stations, without any slippage between the belt and the card. This construction provides for precise control over the movement of the card.The fluorescence station has a linear flash lamp that illuminates a column of the wells of the cards simultaneously. A reference detector and dichromatic beam splitter design is used to insure that the fluorescence measurements are independent of lamp output changes over time.
