How do I integrate a pyrometer into a Czochralski or float-zone silicon growth system?

Silicon crystal growth presents two specific challenges: very high temperatures and significant changes in surface emissivity as the crystal pulls from the melt. The PSC-M322 2-color series handles both, with a 3300°C range and emissivity-independent ratio measurement. Mounting is typically through a water-cooled viewport with an air purge to keep optics clear of silicon vapor. Our application team can specify the right purge fitting and mounting accessories for your puller geometry.
