Our optical grade undoped Czochralski grown monocrystals Lead Tungstate Crystal Substrates with high optical homogeneity excluding the central core of crystal boules, without visible striae with shadowgraph, inclusions, and bubbles.
Lead Tungstate Crystal Substrates have high density, short radiation length, high radiation hardness, small decay constant and moderate price and are promising radiation detection materials.
PbWO4 crystal has the characteristics of fast luminescence, high density, and high irradiance. PbWO4 single crystal is widely used in high-energy physics detection devices and has broad application prospects in nuclear medicine. Due to its good optical properties and stable physical and chemical properties, Lead Tungstate Crystal Substrate is also an excellent photovoltaic crystal material.
