Gp20Na-1 low-pressure sodium lamp
The low-pressure sodium lamp can radiate a strong 589.0nm, 589.6nm sodium line, and has good monochromaticity. It is often used as a monochromatic light source in instruments such as polarimeter, refractometer, and polarimeter.
Low-pressure mercury lamps can radiate strong 253.7nm, 404.7nm, 435.8nm, 546.1nm, 577nm, 579nm mercury lines, often used as monochromatic sources in polarimeter, refractometer, polarimeter, and other instruments.
The lamp is ignited at the rated voltage. When igniting, the ballast must meet the requirements in series. Do not directly insert the power supply. The second and seventh wires of the backlight are the lead wires of the lamp, and the rest are empty feet.
