FTIR accessories for polarized reflection measurement

Jasco introduces the features and specs for their polarized reflection measurement instruments RAS-300 (built-in polarizing mirror model)/H and RAS-310/H (wire grid polarizer model). These instruments are intended for measuring general thin organic films on metal. Jasco designed the RAS-300/H and RAS-310/H in an attempt to improve operability by fixing their incidence angle to 75 degree and allowing measurement simply by placing a sample horizontally on the instrument.

The RAS-300/H was designed with a polarizing mirror for the reflecting mirror which is part of the optical systems so that it can measure light parallel to the plane of incidence. With this model, you are not able to detach or rotate the polarizer. The wire grid polarizer model, the RAS-310H however, allows you to do both.
