High pressure mercury vapor arc-discharge lamps range between 10 and 100 times brighter than incandescent lamps (such as the tungsten-halogen) and can provide intense illumination over selected wavelength bands throughout the visible spectral region when combined with the appropriate filters. The most popular mercury lamp for optical microscopy is the HBO 100 (a 100-watt high-pressure mercury plasma arc-discharge lamp), which has the highest radiance and mean luminance, due to its very small source size, of the commonly used lamps of any wattage.
Mercury arc discharge lamps produce among the highest luminance and radiance output levels of any continuously operating light source for optical microscopy and very closely approach the ideal model for a point source of light.


Aside from the numerous artifacts associated with mercury arc lamps, they also suffer from limited life spans of approximately 200 hours and significant variations in spatial and temporal stability. Presented in Table 1 are the optical output power values of a typical 100-watt HBO light source after passing through the microscope optical train and selected fluorescence filter sets. The rated lifetime of mercury arc lamps depends upon how they are used, and the usual 200-hour limit can be compromised by an excessive number of starts (ignitions) or by repeated ignition of warm or hot lamps. The emission profile of mercury arc lamps is distinct from incandescent lamps in that several prominent emission lines are present in the ultraviolet, blue, green, and yellow spectral regions, which are significantly brighter (up to 100 times) than the continuous background (see Figure 1). A considerable effort has been expended on developing specialized fluorophores that have absorption maxima located near the prominent mercury spectral lines (see Table 2). The extremely high flux density (brightness) generated by mercury arc lamps is achieved by producing the arc in a limited region between two closely spaced electrodes in a high-pressure gas medium. Arc lamp electrode manufacturing variables are critical in determining the starting characteristics, lifetime, and performance variables of mercury lamps. The mercury arc lamp envelope is produced with pure fused silica or quartz glasses, which are impermeable to most gasses at high temperature and pressure, and are thus ideal for containing the hot plasma. One of the most critical features of arc lamp construction is the hermetic metal-to-quartz seal that is necessary to isolate the electrodes from the surrounding atmosphere and for mechanical support of the lamp.
In a typical optical microscope configuration, the mercury lamp is positioned inside a specialized illuminator consisting of a lamp housing containing the lamp, a concave reflector mirror, an adjustable collector lens system to focus the lamp output, an electrical socket for securing and alignment of the bulb, and the external power supply (Figure 3). As discussed above, mercury arc lamps contain a precisely measured amount of metallic mercury within the envelope, and they are filled with argon or xenon, which acts as a starter gas as the mercury vaporizes. Mercury arc lamps require a direct current (DC) power supply that is specifically designed to meet the ignition and operational requirements for each lamp design.


Power supplies for the HBO 100 mercury arc lamps used in optical microscopy are usually equipped with several features that enable the operator to monitor the operating conditions and lifetime.
