The 5000 FEL 1000-Watt tungsten-halogen Lamp Source System provides absolute calibration of spectral irradiance from 250 to 2500 nm. The system can be configured simply as a lamp (bearing the ANSI designation of FEL & calibrated to the 2000 NIST irradiance scale), or to include accessories such as a lamp holder, alignment jig, lamp housing, power supply and shunt box. Lamp calibration is directly traceable to NIST, employing the 2000 NIST scale from 250 to 2400nm.

Model 5000-16A Selected, Seasoned 1000 Watt Tungsten Halogen Lamp
Not calibrated, with bi-post base. Please contact factory for additional information.
Model 5000-16-C Selected, Seasoned 1000 Watt Tungsten Halogen Lamp
Calibrated (250-100nm). Must be used in conjunction with 5000-17 Lamp Alignment Jig and 5000-18 Lamp Holder. Please contact factory for additional information.
Model 5000-17 Lamp Alignment Jig
The Model 5000-17 lamp alignment jig is used to align the 5000-18 lamp holder with respect to the optical axis of the instrumentation to be calibrated. It consists of a rodmounted piece of plane glass that contains intersection scribe marks. These marks are precisely positioned (±0.0005 inch) with respect to the bottom of the medium bi-post base.
Model 5000-18 Lamp Holder
The Model 5000-18 lamp holder is based on the original NIST design as described in NIST tech Note 594-2. Its kinematic design permits precise positioning and repositioning of the lamp standard when used with the 5000-17 lamp alignment jig. Once alignment of the lamp holder is achieved, lamps can be readily interchanged with minimal loss of accuracy. The positioning surfaces consist of one “V-shaped” contact and one “tongue” contact that work with the spring loaded cylinders to precisely secure the lamp bi-posts. An adapter baseplate permits the lamp holder to be mounted directly into Gamma Scientific’s Model 5000-6 lamp housing. This adaptor can simply be removed from the lamp holder in applications that do not require the 5000-6 lamp housing.
Model 5000-6 Lamp Housing
Compact and portable, the 5000-6 lamp housing shields the 1000-watt lamp from users while eliminating stray light from room reflections. A proprietary thermal exhaust design and integrated fans maintain a constant working temperature for the lamp, and an integrated elapsed time meter tracks lamp usage.
Model 5000-6B Precision Shunt Box
The 5000-6B Precision Shut Box provides a high precision dual shunt circuit for monitoring of lamp current. Connections are provided for an external 6.5 digit voltmeter (not included). This item has NIST traceable calibration
