The Vermont Photonics HCDR is a refractometer that uses the Hilger-Chance method to measure the refractive index of glass
slugs cut at 90º.  The HCDR combines customized software with precision angle measurement optics and a high accuracy
rotary encoder.  Index is accurate to ±3x10^-5.  Using a spectral lamp and filter wheel, automated measurements at multiple
wavelengths can be performed quickly and easily, and Conrady and Sellmeier coefficients can be generated to characterize the
dispersion curve of the material.  Custom reports can be generated with data and customer/job information etc.  The
HCDR is a compact unit that fits on a desktop.  Please contact us for more information on the Vermont Photonics HCDR
