OL FEL-B Irradiance Standard (750 – 2500 nm)
Optronic Laboratories offers a 1000-W FEL-B Irradiance Standard. The spectral irradiance calibration of this lamp covers the 750-2500 nm wavelength. The OL FEL-B uses the OL 410-1000 Precision Lamp Source and OL 61 Lamp Holder. We also recommend the OL 62 FEL Alignment Jig and OL 63 Adjustable Lamp Holder Mount.
Optronic Laboratories offers a 1000-W FEL-B Irradiance Standard. The spectral irradiance calibration of this lamp covers the 750-2500 nm wavelength. Each of the 1000-W FEL lamps have a tungsten coiled-coil filament enclosed in a small quartz envelope. The lamp bases have been converted to a medium bi-post base as recommended by the National Institute of Standards and Technology (NIST). This special lamp base improves alignment accuracy, which minimizes uncertainties due to positioning and orientation of the lamp.
