Description:
|
As indicated in the previous booklet in this series,
the Oesper Apparatus Museum contains a
large selection of visual colorimeters, filter
photometers and spectrophotometers based on
collections of these instruments donated in
1990 by the late Melvin Guy Mellon (figure 1)
of Purdue University. Though additional instruments
have subsequently been added, each
of these collections has been named in Mellon’s
honor in recognition of his initial gift. The
M. G. Mellon colorimeter collection was the
subject of booklet No. 4 in this series. The present
booklet (No. 5) deals with his filter photometer
collection, and booklet No. 6 will deal
with his spectrophotometer collection. |
