1000-Watt Lamp Source

  • Product No:5000 FEL
  • Manufacturer:Gamma Scientific

Gamma Scientific’s Model 5000 FEL 1000-Watt Lamp Standard provides absolute calibration of spectral irradiance from 250 nm to 2.4 microns.

This tungsten-halogen lamp standard bears the ANSI designation of FEL. It is calibrated to the 2000 NIST spectral irradiance scale.

The 5000-16C Lamp Standard is a bi-pin 1000 watt lamp that is adapted by Gamma Scientific into a bi-post configuration. It is used in conjunction with the 5000-18 Lamp Holder and 5000-17 Lamp Alignment Jig to obtain a higher degree of accuracy as a result of improved alignment reproducibility.

The 5000 FEL Lamp comes in two models. The Model 5000-16C is calibrated, while the Model 5000-16A is uncalibrated.
