The Lumazone imaging system from Roper Bioscience is offered in various models for quantitative measurements of chemiluminescence and fluorescence emitted by samples, including whole animals and plants. All systems come with a dark box, a camera, an LED light source for bright-field imaging and Lumazone software that offers various image processing and analysis tools. Buyers can choose one of four back-illuminated CCD or EMCCD cameras, or a front-illuminated EMCCD camera, depending on their needs. The cameras all have a 16-bit dynamic range and are cooled. Automated or manual systems are offered. Certain models include emission and excitation filter wheels, a 100- or 300-W xenon light source and a circular neutral-density filter to control lamp intensity.
