Sample Compartment, 10 x 10 mm Cuvettes

The 78100 Sample Compartment holds 10 x 10 x 45 mm cuvettes in an optical beam path to conduct sample analysis. The 1.5-inch series flanges couple to Oriel^® spectrographs, detectors and accessories. The interior baffle design of the 78100 prevents light from reaching the output without going through the cell, and the grooved lid prevents ambient light from entering the compartment. The lid comes off easily for quick insertion and removal of the sample. The 78101 port cover blocks light from entering any unused port.

The 78100 also features an internal filter holder mounted to the inside of one of the ports. Excitation or emission filters may be utilized, without the need for an additional holder. The 78100 holds 2 inch [51 mm] diameter filters, up to 0.12 inches [3 mm] thick. In most applications, the incident light must be collimated and then focused onto the sample. The output beam may need to be re-collimated, or the fluorescing region of the cell could be imaged onto the input slit of an imaging spectrograph.

The 78100 has two external lens holders for 1.5 inch [38 mm] diameter lenses. The clear aperture is 1.2 inches [30 mm]. The distance from the lens to the sample is 2 inches [51 mm]. If longer focal length lenses are desired, Newport offers a selection of spacer tubes.
