Model 66310 QTH Source with 66270 Collimating Lens Assembly, mounted on an optical rod.
If youre looking for a low wattage VIS-NIR source that is inexpensive and easy to operate, choose this source. The 66310 runs our 10 and 20 W QTH lamps. It is an economical alternative to our more versatile Series Q Sources, which hold lamps to 100 W.
The 66310 includes everything necessary to operate the selected lamp. It consists of:
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.
The 63941 is a DC power supply designed to run these low wattage lamps. It is switch selectable for 110/220 V.
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).
The 66275 is a rod mounted bracket that holds the housing at a low optical axis. The lowest centerline height is 2.8 inches (71 mm).
