Optical Stability graph of D2 plus at 254 nm. The included universal power supply comes with common international plug adapters and accepts 90 - 264 VAC, 50 - 60 Hz input voltages. The decrease in the plot is due to decreased efficiency at low wavelengths of the photo detector used to measure the lamp intensity. The Specs indicate a color temperature of 2800 K. This number implies a maximum . thank you, regards, Anna. Figure 2. Tungsten-halogen lamps are pre-aligned, saving time and effort. A halogen lamp, also known as a tungsten halogen, quartz-halogen or quartz iodine lamp, is an incandescent lamp consisting of a tungsten filament sealed into a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen such as iodine or bromine. Tungsten (VIS) Lamps. Can you help to solve this doubt? ... An incandescent light bulb contains a tungsten filament that is resistively heated when a current is conducted through it. Calculate the emission spectra from light sources using COMSOL Multiphysics to find out. All Oriel lamps have similar shaped spectral irradiance curve, but differ in the location and height of the peaks that rely on the model of lamp and operating environment. If a higher color temperature is desired, our color-balancing filters can be used to attenuate red light from the QTH10(/M) light source while passing blue light. Color temperature will vary from unit to unit. The StellarNet calibration facility has a variety of NIST traceable ultra-stable light sources, including UV Deuterium & VIS-NIR Tungsten Halogen covering 200-2500nm range.
