Model 66995 QTH Source with 68951 Light Intensity Controller and fiber optics.
These sources run 50 to 250 W quartz tungsten halogen lamps. The output is a smooth VIS-NIR continuum, useful for radiometry. We offer several families of low wattage QTH Sources; this family is our fully featured Research Series. Choose one of these systems if you need to interchange lamps or have a stability critical application requiring the 68950 Light Intensity Control System.
We offer several families of low wattage QTH Sources (see Table 1 for a comparison). This family is our fully featured Research Series.
All Oriel Sources from Newport come complete with all the necessary components to begin work. These sources include: 10 - 1000 W Research Quartz Tungsten Halogen Lamp Housings 69931 Radiometric Power Supply Your choice of 50, 100 or 250 W Quartz Tungsten Halogen Lamps All necessary cables and mounting hardware
The lamp housing isn't just an enclosure for the lamp, it provides a temperature controlled environment to run the lamp efficiently and it holds the condensing optics and rear reflector to collect the lamp radiation. Reflector and lamp adjusters let you position the filament and its image for highest output.
The 69931 Power Supply runs 50 to 250 W QTH lamps, at a constant current or constant power. Via an RS 232 or IEEE 488 (GPIB) interface, you have full access to all the control and monitoring features of the power supply, from your PC. You can power the supply on and off, set the current/power preset and limit, and monitor the current, voltage, power, and operating hours. For applications requiring long-term output stability we recommend you use the 68950 Light Intensity Controller.
These sources run 50 to 100 W lamps. We have socket adapters to hold the lamp in a vertical (filament is horizontal) or horizontal (filament is vertical) position.
We offer a choice of seven condensers. The condenser is a lens assembly inside a barrel housing with a focusing lever. The condensers are designed to produce a collimated or focused beam. The condenser output has a female flange so you can couple male-flanged accessories, of the appropriate series size. Choose the appropriate condensing assembly based on the following considerations:1. What wavelength range you need2. What F/# you need3. The size of output beam and final image size needed
The housings come with four leveling feet for free standing use. To fix the housing to an optical table or rail, remove the feet and use the 1-inch (25 mm) slots in the housing base. Order the 66075 Carrier Mounting Kit for rail or bench mounting.
QTH lamps have some UV output. Exposed personnel should wear Ultraviolet Safety Equipment. UV hazards are significantly lower for the 66997 and 66998 Sources because the condensers do not transmit below 350 nm.
