5000-FEL 1000 W Halogen Light Source

This 1000 W tungsten-halogen light source produces an absolutely calibrated irradiance of 250 nm to 2500 nm. It can be configured as a simple lamp, but it bears the ANSI designation and is calibrated to the 2000 NIST Irradiance Scale, or together with numerous accessories such as a lamp holder, an alignment jig, a lamp housing, a power supply unit and a shunt box. Calibration is directly traceable to NIST.

The following components can be ordered separately:

Model 5000-16C Halogen lamp

Selected and pre-aged halogen-1000 W FEL lamp with absolute irradiance calibrated at 250-1100nm.

Model 5000-17 Alignment Jig

For the exact alignment of the lamp on the optical axis, contains a flat glass window with grid cross marking.

Model 5000-18 Lamp Holder

The kinematic holder in combination with the alignment jig 5000-17 ensures a precise positioning of the lamp. The base plate allows easy integration into the 5000-6 lamp housing.
