Turbidimeter based on a refractometer using a charge-coupled device

Area x-ray detector based on a lens-coupled charge-coupled device

An area x-ray detector constructed using commercially available “off-the-shelf” parts is described and its performance is characterized. The detector consists of a 1024 1024 pixel charge-coupled device CCD camera optically coupled to x-ray sensitive phosphor screen using a standard 35 mm camera lens. The conversion efficiency, spatial nonuniformity, spatial resolution and the detective quantum ...

Bioluminescence-based ATP assays using a charge-coupled device imaging system.

Quantitative Ultraviolet Measurements on Wetted TLC Plates Using a Charge- Coupled Device Camera

This paper presents the first study of the UV imaging of spots on thin-layer chromatographic plates whilst still wet with solvent. Imaging of spots of benzophenone during and after development was carried out using a charge-coupled device camera. Limits of detection were found to be 5 ng on a wetted plate and 3 ng for a dry plate and the relationship between peak area and sample loading was fou...

A spectroscopic refractometer based on plasmonic interferometry

We describe the design, fabrication, and testing of a spectroscopic refractometer that employs plasmonic interferometry to measure the optical dielectric functions of materials in the visible range. The proposed device, dubbed a plasmonic refractometer, consists of an array of slit-groove plasmonic interferometers etched in a 300 nm-thick metal film (silver or gold) with arm lengths varying in ...

A fast, direct x-ray detection charge-coupled device.

A charge-coupled device (CCD) capable of 200 Mpixels/s readout has been designed and fabricated on thick, high-resistivity silicon. The CCDs, up to 600 microm thick, are fully depleted, ensuring good infrared to x-ray detection efficiency, together with a small point spread function. High readout speed, with good analog performance, is obtained by the use of a large number of parallel output po...
