  1. The apparatus here described was developed in the Optical Instruments Section of the Bureau of Standards during the summer of 1918, and suggestions were contributed by various members of the section. Mr. W. O. Lytle, who was in charge of the binocular testing, made the designs and constructed most of the apparatus. The photometric device and the mil scale projector are the work of Mr. F. S. Brackett, who has also drawn the illustrations for this article.

  4. Let AB be the axis of one telescope and AC the axis of the other, the angle between the two being Q Now let light come to the binocular along the direction of the axis AB, making thus an angle O with the axis of the second telescope, AC. This light will leave the first telescope still traveling in the direction AB, but will leave the second telescope along a direction A′E, such that the angle CA′E is M times O. The angle DBE, to which the eye has to accommodate itself, is hence (M - 1) O.
