Absorption readings of dichromate solution standards were made with 9 Cary-14 spectrophotometers and 16 Cary-11 spectrophotometers. Agreement among instruments was somewhat better than that obtained in previous similar studies with ultraviolet solution standards.
The absorption spectra of two glass filters were determined in the near infrared region with the Cary-14 spectrophotometers. Wavelength and absorbance readings were in excellent agreement.
