PKS-250M Polariscope / Polarimeter for determining double refraction in flat blanks and products of transparent and weakly tinted materials.
Highlights:
- quantitative assessment of double refraction value by Senarmon method with an error of not greater than 10 nm,
- assessment of double refraction distribution in an object by interference tinting,
- examining distribution of double refraction in an object with circularly polarized light.
- large observable field for monitoring of large blanks and products and simultaneous monitoring of a few specimens.
