The cost structure of quartz lens mainly includes material, dimension size, dimension precision and process complexity. 1.Materials : common materials that can pass through UVC are synthetic quartz JGS1, fused quartz JGS2 and sapphire. The transmittance of synthetic quartz JGS1 is 1-3% higher than that of fused quartz JGS2 in the UVC 250-280nm band, and its price is several times higher than that ...
