Instrument for laboratory use include the following:QSL-2100 in the foreground with the QSL-2101 (smaller sphere) behind. Also shown are variants for field work
QSL-2100: PAR Scalar Irradiance sensor with digital RS-232 interface and Logger2100 Software. The light collector is a TeflonTM sphere 1.9 cm in diameter on a 25 cm rigid light pipe suitable for immersion in culture vessels. The long light pipe is particularly convenient when used in growth chambers for organisms such as photosynthetic bacteria, plankton, kelp, and higher plants. This instrument replaces the QSL-100 that is in use in hundreds of laboratories worldwide.
QSL-2200: Similar to the QSL-2100, but with an analog interface suitable for use with data loggers and industrial automation systems.
QSL-2101, QSL-2201. The 1.27 cm diameter collector on the QSL-2101 (digital output) or the QSL-2201 (analog output) is specifically designed for insertion in vials of the type commonly used in photosynthetrons.
AMOUR: This is the newest device in our laboratory sensor series. In addition to being available with either a 1.9 cm or 1.27 cm diameter Teflon scalar irradiance collector, it is also available with a "cosine" irradiance collector or radiance input optics, and is available with a wide variety of spectral responses. This sensor has superior dynamic range (10 decades), and has a USB connector, which plugs directly into a PC.Optical collectors available for AMOUR
