HLS-1000 Halogen Tungsten Light Source
HLS-1000 halogen tungsten light source is a versatile light source, suitable for VIS-NIR (340 nm-2000 nm), can be used for sample detection in absorbance transmittance. The light source can adjust SMA905 connector. The cooling fan cools and stabilizes the light source. Filter can be embedded in groove at light exit port.

Related Applications and Solutions
1. Transmittance Measuring Experiment
In this experiment, the HLS-1000 halogen-tungsten light source is connected to a three-channel sample cell and a cuvette by optical fiber. The light beam passes through the cuvette and another fiber is connected to Aurora 4000 high-resolution spectrometer which is produced by our company. The transmittance of the liquid is obtained by software operation.

2. Reflectivity Measuring Experiment
In this experiment, a specially designed Y-type fiber is connected to the HLS-1000 halogen tungsten light source, and the receiver is connected with the Aurora 4000 high-resolution spectrometer which is produced by CNI. The probe part of the optical fiber is fixed on the optical fiber support, facing to the test samples. The reflectivity of the object can be obtained by software operation.
