Exicor reference samples are built to ensure repeatable measurement over time. They are built for stability over time and temperature for several different retardation levels.

There are three models:

• Low birefringence (<2nm)
• Mid-birefringence (<20nm)
• High birefringence (<100nm)

Low birefringence (<2nm)


Mid-birefringence (<20nm)

High birefringence (<100nm)
