Appl. No.:

11/148140

Inventors:

Scott Wilson - Lafayette CO, US
David H. Davies - Boulder CO, US
David L. Blankenbeckler - Longmont CO, US
Steven H. Ray - Longmont CO, US

Assignee:

DPHI Acquisitions, Inc. - Longmont CO

International Classification:

G11B 7/00

US Classification:

369121, 36911223, 369 4419

Abstract:

A small form factor optical disk drive is provided that incorporates a SIL/objective lens assembly. A laser for the small form factor optical disk drive has a coherence function having maxima spaced apart by intervals. The optical disk drive is configured such that a roundtrip optical path through the SIL/objective lens assembly is such that a coherence value for the laser is located in one of the intervals.

International Classification:

H01J 49/26
H01J 49/40
B01D 59/44

US Classification:

250287, 250281, 250282, 250288, 31511161, 31511181

Abstract:

Novel methods and instrumentation for mass spectrometry are described. Zoom-time of flight mass spectrometry (Zoom-TOF) allows increased mass resolution over a pre-determined specific range of masses. Methods for retrofitting traditional time-of-flight (TOF) and distance of flight (DOF) mass spectrometers are described, as well as novel instruments capable of performing Zoom-TOF analyses.

International Classification:

H01J 49/40
H01J 49/34

US Classification:

250287, 250282

Abstract:

A combined distance-of-flight mass spectrometry (DOFMS) and time-of-flight mass spectrometry (TOFMS) instrument includes an ion source configured to produce ions having varying mass-to-charge ratios, a first detector configured to determine when each of the ions travels a predetermined distance, a second detector configured to determine how far each of the ions travels in a predetermined time, and a detector extraction region operable to direct portions of the ions either to the first detector or to the second detector.
