DH-Si

The DH_Si ultraviolet silicon photodiode offers excellent linearity and low noise over the UV-vis-NIR spectral range. 

Housing a 10x10mm (200-1100nm) active-zone silicon photodiode, the DH_Si operates in photovoltaic mode. The photocurrent generated by this detector is best measured using the 487 picoameter or the 477 preamplifier followed by the 496 lock-in amplifier. 

The mounting flange supplied with the DH_Si is compatible with the full range of Bentham monochromators and accessories. A quick-change variant is also available.
