The Berek compensator operates by tilting a uniaxial crystal plate (typically calcite) in the polarized light path — the tilt angle introduces a known retardation that can be used to null the retardation of the specimen under observation. By reading the tilt angle at extinction and applying the Berek compensation formula, the precise retardation of the specimen can be calculated in nanometers or as a fraction of the wavelength. With a 3λ measuring range, the U-CBE accommodates specimens with retardation values from near-zero up to three full wavelengths — covering the majority of birefringent materials encountered in mineralogy, polymer science, pharmaceutical crystallography, and biological research. The U-CBE is designed for use with the Olympus U-TAD transmitted light analyzer\/polarizer assembly on BX series microscopes. Built to Olympus factory specifications, it delivers the optical precision required for quantitative compensator measurements.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp style=\"font-family:'Segoe UI Emoji', sans-serif;\"\u003e\u003cstrong\u003e🔎 Typical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMineralogy and petrology — quantitative retardation measurement for birefringence determination in thin sections\u003c\/li\u003e\n\u003cli\u003ePolymer science — measuring optical path difference in oriented polymer films, fibers, and composites\u003c\/li\u003e\n\u003cli\u003ePharmaceutical crystallography — characterizing birefringence of crystalline drug substances and excipients\u003c\/li\u003e\n\u003cli\u003eBiological research — quantifying retardation in collagen fibers, muscle myosin, and other birefringent biological structures\u003c\/li\u003e\n\u003cli\u003eMaterials science — stress and strain birefringence measurement in glasses, ceramics, and optical components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp style=\"font-family:'Segoe UI Emoji', sans-serif;\"\u003e\u003cstrong\u003e📊 Key Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOlympus Part Number\u003c\/td\u003e\n\u003ctd\u003eU-CBE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eBerek Compensator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Range\u003c\/td\u003e\n\u003ctd\u003e3λ (3 lambda)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Method\u003c\/td\u003e\n\u003ctd\u003eTilt-based calcite plate retardation nulling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Analyzer\u003c\/td\u003e\n\u003ctd\u003eOlympus U-TAD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Microscopes\u003c\/td\u003e\n\u003ctd\u003eOlympus BX series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHS Code\u003c\/td\u003e\n\u003ctd\u003e901190\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eNew \/ OEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003cp style=\"font-family:'Segoe UI Emoji', sans-serif;\"\u003e\u003cem\u003eUniversities and research institutions are welcome to purchase using an official purchase order.
