POL-D4:Built-in sodium lamp, supporting 50/100/200 mm tubes. Ideal for routine testing, education, and budget-sensitive projects.
POL-D4I: Enhanced sodium lamp version with 4X magnification for clearer readings. More stable structure, suitable for long-term use in industrial QC labs.
POL-D4L: Energy-saving LED light source with longer lifespan and no preheating needed. Lighter weight, perfect for frequent use or mobile testing applications.
Disc Polarimeter Operation Step:
Switch on the power, the polarized light beam radiatesto the polarizer filter. The operator is able to observe the distinctvisual fieldsthrough eyepiece. Put the glasssample tube into the measurement chamber, rotate the vernier knob until the visual fields appear the equal brightness. Read and record the measured values from the vernier scale, the measurement is completed.
Disc Polarimeter Feature:
The disc polarimeter is precision engineered to provide highly accurate spin measurements.
Wide wavelength range to accommodate different samples at different wavelengths.
The disc polarimeter is simple to operate, making it easy for even beginners to get started.
