Quantitative Circular Dichroism: qCD
Laser Flash Photolysis
Interest in conjugated polymers used in e.g. photovoltaic cells has grown over recent years and there is considerable interest in advancing organic photovoltaic devices (OPV) by systematic optimisation of device processing conditions and development of new materials. The use of laser flash photolysis in the near infrared region allows direct monitoring of photogenerated charges.
Charge photogeneration at donor/acceptor heterojunctions is the basis of the function of organic solar cells. Extensive attempts are currently being made to improve OPVs. A clear understanding of OPVs is crucial for systematic optimisation of processing conditions and the choice and development of materials employed. A blend of P3HT and PCBM is involved in one of the highest efficiency solar cells to date. The yield and lifetime of the generated charges can be measured using transient absorbance spectroscopy.

COOKE VACUUM designs and manufactures a wide range of standard and custom high and ultrahigh vacuum systems intended for research and production. With five decades of experience, and thousands of units in the field, COOKE VACUUM has come to symbolize economy and versatility,
Cooke Vacuum Products was established in the late 1950’s during an exciting period of experimentation in vacuum technology, especially thin film coating and materials research. From the beginning, Cooke had to pioneer new applications and new tools for the emerging semiconductor and optical industries, and for the related research laboratories.
Over the next decades, Cooke continued to support R&D by developing pumping systems, resistance evaporation, electron-beam, sputtering, and plasma sources, often in close collaboration with customers. Vacuum environmental chambers were developed for the space industry, encapsulation and bake systems for early flat panel displays. New, and highly specialized equipment was made for the quartz crystal industry, as well as for production of printing foil, then holographic foil. We were there to make the first OLED systems, and the first glove-box processors.
Because of the emphasis on custom solutions, the company has remained relatively small, and is well-known for its ability to “engineer on demand” more than for volume production.
Thin Film Deposition: Thermal Resistance; Electron Beam; Sputter; PLD; OLED and Glove Box Systems.
Etch/Ash/Surface Treatment: Plasma Etch; Reactive Ion Etch; Surface Activation and Modification.
Test and Specials: Environmental Test; Space Simulators; Vacuum Ovens: Laser Die Attach.
The LE Model Laser Extensometers are precision, wide-range instruments specifically designed for accurate, non-contact measurement of strain on various materials under tensile or compressive conditions. They may also be utilized for other applications where non-contact measurement is desired. The LE models are completely self-contained and are housed in a single compact enclosure. They take advantage of the latest laser technology in order to achieve high performance with minimal maintenance.
The Model LE Laser Extensometers provide: a digital display; 4 button keypad; analog output; and an RS-232 computer interface; all of which are located on the back panel. Instrument operation may be from the back panel or remote via the RS232 interface.
Although these instruments are designed to handle a wide range of measurement applications, the Model LE Laser Extensometers are easy to operate. They utilize a unique scanning laser beam technique to measure dimension changes from one side of the subject, eliminating the need for a scan receiver on the opposite side. For special applications requiring transmission around or through a specimen or other object, alternate methods can be implemented.
Since 1974 Glass Fab Inc. has met customers stringent specifications by providing fabricated parts made of optical glass, filter glass, fused quartz and silica, low expansion materials, and various other optical materials.
