Sarspec high-power light source LS-DWHP

Product Name:Sarspec high-power light source LS-DWHP

Product Model:LS-DWHP

Product Introduction

LS-DWHPIt is a stable light source that combines the continuous spectra of two high-power deuterium lamps and tungsten lamps in one fiber optic cable In SMA connectors, the connector has an adjustable focusing lens component. The combined spectrum of these two lamps produces an output between 180 and 2500 nm, providing light quantity for absorbance, transmittance, and reflectance measurements.

The integrated shutter on the LS-DWHP light source simplifies the operation of dark measurement and limits UV exposure without the need to turn off the light source, while the lamp selector allows for easy selection of single or combined deuterium and tungsten lamp operation. As a supplement to its high-power lamps, the DWHP light source has a built-in filter slot that can accommodate a filter holder to narrow the wavelength range or reduce light intensity.
