ATAGO® DR‑M2 Multi‑Wavelength Abbe Refractometer

ATAGO® DR‑M2 Multi‑Wavelength Abbe Refractometer

The ATAGO® DR‑M2 is a high‑precision multi‑wavelength Abbe refractometer engineered for advanced optical analysis, allowing measurement of refractive index or Abbe number (νd or νe) across wavelengths from 450 to 1,100 nm. The instrument digitally displays refractive index or Abbe number on a bright LCD panel, and measurement is performed by aligning the boundary line with the intersection of the crosshairs. The DR‑M2 is widely used in optical material development, resin formulation, lens manufacturing, and research laboratories requiring wavelength‑dependent refractive index evaluation. This model is also connectable to the optional Digital Printer DP‑AD(B) for streamlined documentation.
