Thorlabs' SLS203F(/M) Stabilized Globar Light Source provides a constant-intensity, 1.8 W blackbody radiation spectrum from 500 to 9000 nm in free-space applications and 500 to 4500 nm using the included fiber focusing package and ZBLAN fiber patch cables (sold separately). Since the blackbody spectrum spans the visible and mid-infrared spectral ranges, this source is ideal for integration into mid-IR measurement and analysis systems. It uses a silicon carbide Globar that is housed in an ellipsoid reflector to increase the optical output.
An internal feedback system is employed to achieve a highly stable power output. The superior performance of Thorlabs' stabilized light sources makes them ideal for experiments that require high accuracy and stability, such as transmittance and reflectance measurements. A LA5370 Plano-Convex Lens inside the main housing coarsely collimates the output light and the included fiber package focuses it down onto a fiber tip. The included filter holder is interchangeable with the CFH2-F filter holder, sold below. The SLS203 collimation package (sold separately below) produces a beam with lower divergence.
