Wavelength Repeatability of a Cary Model 14R Spectrophotometer.

摘要

In our laboratory Cary spectrophotometers are used to measure the transmittance of optical components and materials. One instrument in particular, a Cary Model 14R spectrophotometer, is used to calibrate narrow-band interference filters. The precision of the wavelength measurements was determined using the D sub beta line of the deuterium source lamp as a wavelength standard. (Author)
