I am interested in your QTH10/M Quartz Tungsten-halogen Lamp so I can calibrate a spectrofluorometer. The deuterium lamp's … The CRI is 100 as well. Dear Thorlabs, how reliable is the provided spectrum? Dear Thorlabs team, I'm looking for the emission spectrum, could you provide me with such an information, please? SM2T2 Lens Tube Coupler Attaching QTH10 Lamp to LCFW5 Filter Wheel. Germany. The absolute amount of light power is not so interesting for me, the relative power versus wavelength should be known with a few percent precision though. Buechtemann mentioned "The spectrum supplied via graph and Excel sheet has its maximum at 621 nm". To power the bulb, a universal power supply (90 - 264 VAC) with plugs for all regions is included. We offer VIS or tungsten halogen lamps for HPLC equipment by Agilent, Shimadzu, Beckman and many more. Spectrum of halogen (reflector) lamp. The spectrum intensity does not actually decrease from 250 nm to 200 nm as shown in the spectrum plot above. We strongly recommend the use of gloves (such as latex or cotton gloves) when replacing the bulb in order to prevent skin oils from being deposited on the glass. It seems that an inner diameter (1 mm) of this connector not corresponding picture of QTH10/M. A representative spectral distribution is shown in Fig. published and measured emission lines, as seen in Figure 12. thanks! The spectral distribution of the irradiance from the 6315 Lamp at its rated voltage is illustrated in Figure 2. As the name implies, the emission of three-band sources tend to be concentrated in three bands of the spectrum. Tungsten halogen lamps provide a continuous spectrum from 315 nm to over 2000 nm. Select products. The included universal power supply comes with common international plug adapters and accepts 90 - 264 VAC, 50 - 60 Hz input voltages. To prevent the tungsten wire from burning up, the bulb is filled with a gas, usually argon. We have removed that plot until we have completed further testing across various batches. I'm considering to use the lamp as an intensity calibration source for a CCD. Can you help to solve this doubt? However, it seems to me your application might benefit from a broadband stabilized source instead like the ones at the following link: http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_ID=7269, Hello, For liability reasons, please verify all laser goggle selections with your local laser safety office who would have access to the complete specs of this light source and how it will be used in your application. Callum J. Hello Callum, I have reached out to you directly with this information. Whether it would be suitable as an approximation would depend entirely on the tolerances of your application, but we would not be able to guarantee it against any NIST-traceable or similar standard. With the stabilized tungsten light source (SLS201L), a plot of spectral power distribution compared to a true blackbody is provided. This lamp is not intended for use in household illumination applications. Adapters are available separately to couple the free-space output into liquid light guides (LLGs). The QTH10B is a replacement light bulb for the QTH10(/M) Quartz Tungsten-Halogen Lamp. I will follow-up with you regarding the percentage fluctuations of the relative intensity with wavelength. This lamp is not intended for use in household illumination applications. Can this product be used as a blackbody calibration source as a 2800K temperature blackbody? We will reach out to you directly with this information. Due to high temperature tungsten filament gets evaporated during working & also due to conventional flow of gas inside the bulb, the evaporated tungsten is transported away from the filament. description: tungsten industries slc150w-1 slc150w1 discontinued by manufacturer bulb 150w wide spectrum halogen light available surplus never used surplus 2 year radwell warranty lamp type: halogen lamps For the best imaging quality, the filament should be oriented perpendicular to the optical axis. I'd read in specification about strange inner diameter: "Output Connector: 1 mm ID x 5.5 mm OD x 9.5 mm Long (Female)". This lamp is controlled just by connecting it to its power supply. With increase in operating pressure, line spectrum broadens and colour distortion is reduced. Hi, The wall of the bulb is relatively cool. We are looking to update the expected Spectrum after additional testing, as the current plot of the spectrum does not match the bulb's specs. 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. Power at Fiber Tip at Maximum Bulb Intensity. Replacement bulbs (Item # QTH10B) are available below. Integrating sphere light sources with continuous emission spectrum. They lack radiation in some wavelengths resulting in colour distortion of some objects seen under these lights. Lamps for special luminaires; Medical fiber optics (HLX) Family data sheet. The power supply connector barrel plug is actually 2.1mm ID x 5.5mm OD x 9.5mm Long (female). Tungsten (VIS) Lamps. Tungsten halogen lamp based uniform light sources with manual and remote control variable intensity. The decrease in the plot is due to decreased efficiency at low wavelengths of the photo detector used to measure the lamp intensity. After warming up, the heat sink will reach a temperature of 50 °C. The tungsten-halogen capsule can be positioned inside the light-transmissive envelope. What inner diameter is correct? Monitor detectors. I will reach out to you directly with preliminary testing done on a QTH10 lamp. Thank You. The deuterium lamp emits radiation extending from 112 nm to 900 nm, although its continuous spectrum is only from 180 nm to 370 nm. Used in conjunction with deuterium lamps, tungsten lamps provide the wide ranging output required in UV/VIS spectrophotometers. Compared to standard lamps up to 10 % higher luminous efficacy (HLX) Instant light (HLX) Areas of application. This is not the case when halogen like iodine is used in the bulb container. I will reach out to you directly to discuss your application. Is this data available for the QTH10 light source? Hence here also tungsten will be evaporated from lamp fila… Viele übersetzte Beispielsätze mit "tungsten halogen lamp" – Deutsch-Englisch Wörterbuch und Suchmaschine für Millionen von Deutsch-Übersetzungen. More downloads . Please see Section 3.4 of the QTH10(/M) instruction manual for installation instructions. IR blocking glasses will be most suitable for this type of light source.
