Robust Optical Connection Between the Process and the Sensor
Luxtron is the world's leading supplier and designer of lightpipe optical systems for radiation thermometers. Lightpipes act as a conduit, taking light from the hot object and directing it to the radiation thermometer's detection electronics.
Luxtron lightpipes are usually constructed of sapphire, but sometimes of quartz. While the sapphire is more expensive, the advantage is that the single crystal sapphire can survive many of the harsh environments encountered in modern industrial processes.
In general, the advantages of lightpipes are: - Small size makes them easy to integrate into process chambers,
- Ability to collect light from a wide-angle helps to reduce emissivity and surface roughness errors that can occur using lens based optics,
- Sapphire material is immune to most corrosive environments, and
- Sapphire has a high melting point allowing it to survive temperatures up to 2000°C.
