Dual Channel Photometer, Optical Building Blocks, a Division of HORIBA Scientific (CAT#: STEM-LE-0801-LC)

The 4301 photometer is equipped with an eyepiece to visually observe what will be detected on the microscope stage. By adjusting the pair of vertical and horizontal apertures in the field of view, it is possible to isolate a small number of cells, a single cell or even a part of the cell for measurement. The diachronic beam splitter is placed in the photometer to direct the appropriate emission wavelength to each detector for simultaneous double detection. The duration beam splitter can be easily changed to select the desired emission wavelength.

Cheap and versatile — OBB photometers are versatile and can be adapted to microscopes of any manufacturer through a standard C-mount mount on the discharge port. You will never be tied to a specific range of manufacturers, so the cost is lower.
Adjustable detection range-users can intuitively see and select the desired detection field of view.
Eyepiece-allows the user to intuitively identify the area to be measured.
Wavelength selection-use a cheap standard 1 inch filter for wavelength selection.
Analog detection mode-high sensitivity and maximum dynamic range.
Wide spectral bandwidth-from UV to NIR detection capabilities.
Dual wavelength detection-two wavelengths can be detected simultaneously.
Complete software-for data collection and analysis.
