| MULTI-WAVELENGTH ABBE REFRACTOMETER |
DR-M4 |
| Cat No.1414 |
Refractive index or
Abbe number(νd orνe) can be measured at different wavelengths
ranging from 450 to 1,100nm(For measurement at wavelengths ranging
from 681 to 1,100nm, the optional Near Infrared Ray Viewer(RE-9115)
is required.)
The DR-M4 displays measurement result of refractive index or
Abbe number digitally on the LCD.
Measurement can be achieved by matching the boundary line with
the intersection point of the cross hairs.
This refractometer is connectable with digital printer DP-21(B)(optional). |
