DR-M2 Refractometer – Refractive index measurement at different wavelengths

The DR-M2 Refractometer can measure refractive index at different wavelengths from 450 nm to 1100 nm.

Specifications:

• 450 nm: RI 1.3277 to 1.7379
• 589 nm: RI 1.3000 to 1.7100
• 680 nm: RI 1.2912 to 1.7011
• 1,100 nm: RI 1.2746 to 1.6843

Refractive index or Abbe number (νd or νe) can be measured at different wavelengths from 450 to 1,100 nm. The DR-M2 digitally displays the refractive index or Abbe number measurement result on the LCD screen. Measurement can be achieved by matching the boundary line with the intersection point of the cross hairs. This refractometer can be connected to the digital printer DP-AD(B) (optional).
