High quality polarized lenses, like SunRx® polycarbonate polarized lenses, ofer the best protection from harmful UV light and blinding glare. It’s important for anyone who sells or dispenses polarized lenses to understand how they work and to be able to explain to patients how they difer from conventional sun lenses.
A computer-interfaced polarized optical microscope with a laser source at 543.5 nm (Figure 9) was constructed on the optical bench and used to inspect the lenses on a microscopic scale and to...

Cut-away diagrams of the objectives reveal internal lens elements, which are corrected for chromatic and spherical aberration. The objective on the left is a low-power 4x objective designed to view birefringent specimens at lower magnifications.
A phase contrast microscope, a reflected-light (metallurgical) micro-scope, and a biomedical, clinical-type microscope fit-ted with polarizing filters, as are commonly provided, are inadequate. The microscope must be a true polar-izing microscope, as will be described later in detail. Figure 2-14.
Polarized lenses selectively absorb glare to allow good optical acuity and comfort, even in bright sunlight. But not all polarized lenses are equal in quality and performance.
Polarized light microscopy (PLM) is a technique which employs the use of polarizing filters to obtain substantial optical property information about the material which is being observed.
