摘要：

The design and performance of a beam condenser for ir spectrophotometers such as the Beckman model IR-11 is described. The instrument has an image size of 4 mm X 8 mm and permits the use of samples mounted in the tail of a cryostat whose outside dimension is as large as 7 cm square. Applications to negative light flux spectroscopy are described, in particular, the direct measurement of the longitudinal optical frequency of lattice vibration for AgBr and AgCl. © 1969 Optical Society of America.
