Isotope Rubidium 85 Reference Cell (diameter 22.68mm, length 71.2mm)

These flame sealed batteries contain a small amount of solid under vacuum, with a chemical purity of>98% and isotopic purity of rubidium 85 (85Rb). The concentration of rubidium in the gas phase can be controlled by heating the battery or cooling the tip rod. The working temperature is usually between 20-80 ° C. Rubidium has intermittent strong absorption lines and is used for calibrating tunable lasers and wavelength meters in the range of 6540-48300 cm-1 (207-1529nm). They can also stabilize the laser frequency by locking onto a single strong absorption line. The quartz pool body is cylindrical in shape; Outer diameter 22.68mm; Length 71.2mm. The pointed stem is centered around the cell and protrudes no more than 10mm from the cell body. The window forms an angle of 11 ° with the normal direction and has a 2 ° internal wedge to prevent back reflection and standard instrument effec
