What Makes up a 66310 QTH Source? |
The 66310 includes everything necessary to operate the selected lamp. It consists of: |
|
Rod Mounted Lamp Housing |
The 63205 Housing is an inexpensive enclosure for the lamp. It has a 0.93-inch (23.5 mm) diameter opening and a filter holder. Use 1 inch (25 mm) diameter filters, for wavelength selection. The base of the housing has a socket adapter that holds either lamp in a horizontal position. Operating the lamp in a horizontal configuration produces an image of the filament that is better suited to illumination of a vertical monochromator slit. Rod mounting, utilizing the 1/4-20 tapped hole in the housing base, allows height adjustment of the optical axis. |
DC Power Supply |
The 63941 is a DC power supply designed to run these low wattage lamps. It is switch selectable for 110/220 V. |
Collimating the Output |
The 63205 Housing does not come with a collimating lens, but we offer the optional 66270 Collimating Assembly. This is a bracket with lens holder that mounts to the lamp housing and allows positioning of a 1.5-inch (38 mm) diameter lens one focal length away from the lamp. Use lenses with focal lengths between 40 and 75 mm, and a maximum thickness of 13 mm. We make some recommendations below. The clear aperture of the lens holder is 1.3 inches (33 mm). |
