65130 and 65010 High Power Spectral Line Lamps
Choose these sources if you require very intense, discrete spectral lines. These lamps are approximately 2X more intense than comparable Pencil Style Calibration Lamps, although the spectral intensity distribution is very different. See Fig. 1 for the irradiance from the 65130 High Power Mercury Lamp. The lamps are housed in the 65160 Lamp Housing, and powered by the 65150 Regulated AC Power Supply.
The lamps are operated in the 65160 Housing. A socket adapter holds the lamp so the direction of maximum radiance is through the lamp-housing aperture. The same socket holds any of these high-powered spectral line lamps so you can interchange between the lamps without switching lamp mount.A filter holder at the aperture holds 1-inch (25.4 mm) diameter interference filters for wavelength isolation. The 65160 can be rod mounted using standard 1/4-20 threaded optical rods. A rod is not included. A 6 ft. (1.8 m) long cable is included to connect to the 65150 Power Supply. To ensure the greatest flexibility we offer a Z Bracket accessory.
These lamps operate in AC mode. The output stabilizes after a few minutes of warm-up. Because the power supply operates in regulated AC mode, there are rapid variations in output on an ms time scale; see Fig. 2. However, the average output over many seconds is very stable. In fact, input voltage variations of as much as 10% are removed by the regulation circuit so you only see changes of less than 1% in light output.
The radiating material is enclosed in a compact burner. Starter gases are used with the metallic elements. The burner is surrounded by a glass tube for thermal insulation and mechanical protection. Several of the lamps have a quartz tube for transmission of the UV.
The 66275 Z Bracket lets you rod mount the 65160 Lamp Mount at a low optical axis height to match our monochromator inputs. The lowest centerline height with this mount is 2.8 inches (71 mm).
The following are commonly used spectral lines from these lamps.
Although these are low wattage sources, they still emit hazardous UV radiation. Be sure to wear protective eyewear and gloves.
