摘要:
A cell holder and photometer for use with the Beckman Model DU spectrophotometer is described. The cell holder is designed to position capillary cells of small diameter, e.g. 0.7 mm and 5 cm in length in the narrow beam of light passed through fine collimating masks. The capacity of the cells is about 20 mm3which allows analysis of quantities about 10 times smaller than have been hitherto analyzable. The photometer employs a multiplier phototube in order to achieve the requisite sensitivity for the small amount of light transmitted.

摘要:
A high speed flash tube is adapted to the Nordensen retinal camera, so that the fundus of the human eye can be photographed in color. The high speed flash eliminates the usually deleterious effect of blinking and eye movements. Special electronic circuits are needed to provide a flickering light from the same flash tube to enable the operator to adjust and focus the camera. Ektachrome film is used and this is over‐developed to gain equivalent exposure. For the fundus photographs this apparently results in no loss of color relationships.
