Description

Visible light microscopes for observing any samples, transparent or opaque, at magnifications up to 4000 x. Also equipped with video cameras to capture dynamic events, such as emulsification processes or sample change due to temperature. Uses a PC-based image processing system for image acquisition, processing, and analysis.

Equipment

Two Nikon Optiphot-Pol microscopes for transmitted and reflected light studies. Polarized light, phase contrast,dark field,fluorescence, and Nomarski differential interference contrast (DIC) illumination are available. A monochrome or color video camera relays the microscope image to a computer image processor for background subtraction, contrast enhancement, filtering, and other processing options.

Accessories

• A Temperature stage, -20 °C to 100 °C
• A flow cell
• Dage MTI series 68 Newvicon tube monochrome video camera
• Dage MTI DC-330 3-chip color video camera
• Dage VE-1000 SIT-intensified camera for low light applications, i.e. birefringence or fluorescense

Applications

DIC:

• imaging of low contrast objects
• study of changes in the microstructure of surfactant and lipid vesicles with variations in pH, temperature, or counterion concentration
• determining interfacial tension of polymers through melting characteristics

Specifications

• 0.2µm ultimate resolution
• measurement of objects as small as 0.4µm,
