🔬 Olympus U-CBE Berek compensator — 3 lambda (3λ) measuring range, for quantitative retardation measurement in polarized light microscopy⚡ 3λ measuring range — covers retardation values from near-zero to 3 full wavelengths for a wide range of birefringent specimens🎯 Precise tilt-based compensation — the Berek design uses a tilting calcite plate to null specimen retardation with high accuracy🏭 Made in Japan by Olympus — guaranteed OEM fit and optical precision✅ SKU U-CBE — new condition, for use with U-TAD analyzer/polarizer, compatible with Olympus BX series 🔧 Product Description The Olympus U-CBE is a Berek compensator with a 3 lambda (3λ) measuring range, designed for quantitative optical path difference (retardation) measurement in polarized light microscopy on Olympus BX series microscopes. 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. 🔎 Typical Applications Mineralogy and petrology — quantitative retardation measurement for birefringence determination in thin sections Polymer science — measuring optical path difference in oriented polymer films, fibers, and composites Pharmaceutical crystallography — characterizing birefringence of crystalline drug substances and excipients Biological research — quantifying retardation in collagen fibers, muscle myosin, and other birefringent biological structures Materials science — stress and strain birefringence measurement in glasses, ceramics, and optical components 📊 Key Specifications Specification Details Olympus Part Number U-CBE Type Berek Compensator Measuring Range 3λ (3 lambda) Measurement Method Tilt-based calcite plate retardation nulling Compatible Analyzer Olympus U-TAD Compatible Microscopes Olympus BX series Country of Origin Japan HS Code 901190 Condition New / OEM Universities and research institutions are welcome to purchase using an official purchase order.
