Features

top
The Model DR-M Series Abbe Refractometers, featuring multiple wavelengths and automatic Abbe Number measurement are the first instruments of their kind for the high-level Refractive Index analysis of liquids, glass, plastic, & film.

Easy to Use. Operation consists of placing a sample on the prism; inserting an interference filter in the light source; while looking through the eyepiece, the control knob is turned until the shadowline is centered in the crosshairs (see Eyepiece View); the reading is shown on the large LCD display. Units calibrate with water (Model DR-M2) or the included glass standard.

Professional Features. Large, menu-driven LCD display; primary & secondary prisms; color compensator
dial; large measurement dial; focusable eyepiece; desiccant case; drain nozzle.

Multiple Wavelengths. Measures at 589nm (vD) or 546nm (vE) with the two included interference
filters. Capable of measuring in the range of 450-1100nm with the use of optional interference filters. For testing above 680nm, the optional infrared Viewer is required. External halogen light source features digital readout, variable intensity, and adjustable positoning of the light guide.

Abbe Number Measurement. Automatic; digital readout of Abbe Number (vD & vE) in 4 easy steps. For vD, the included 589nm interference filter and the optional 486nm & 656nm interference
filters are used. For vE, the included 546nm interference and the optional 480nm & 644nm interference filters are used.

Digital Accuracy. High resolution and accuracy provides substantial precision for both liquid and solids testing. The digital display and simple operation both enhance overall precision - no analog scales to read.
Prism Temperature Control. Featuring 2 circulator nozzles for the primary prism and 2 for the secondary prism, The DR-M Series models can be connected to a circulating bath to accurately regulate prism temperature. The prism temperature is displayed on the LCD display. The effective temperature range is 5-50°C.

Glass, Plastic, & Film Testing. Transparent or translucent glass and plastic samples can be measured
with the use of the included contact liquid. Transparent or translucent film samples can be measured with the use of the included contact liquid and lighting glass. Note: The refractive index (nD) of the sample must be lower than that of the contact liquid. The included bromonapthalene contact liquid has a refractive index (nD) value of 1.6300; the included methylene iodide solution (Model DR-M4 only) has a refractive index (nD) value of 1.7400.

Double Refraction (Birefringence) Testing. With the optional polarizing eyepiece, the DR-M Series models can test samples exhibiting double refraction.

Refractive index or Abbe number (vd or ve) 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 is required.)

The DR-M2, DR-M4 display 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. These refractometers are connectable with a digital printer (optional).
