Pl. Polavarapu et al., POLARIZATION DIVISION BEAMSPLITTERS WITH KBR AND KRS-5 SUBSTRATES FORFOURIER-TRANSFORM INFRARED-SPECTROSCOPY, Applied spectroscopy, 50(1), 1996, pp. 98-101
Polarization-division beamsplitters with KBr and KRS-5 substrates were
constructed and evaluated for their performance in Fourier transform
infrared spectroscopy. It is found that the beamsplitter with a KRS-5
substrate is not practically useful; the one with a KBr substrate has
good potential, although its current performance is significantly poor
er than the performance of a beamsplitter with a BaF2 substrate. Repre
sentative spectra obtained with a KBr beamsplitter are presented.
