On this
web page, you will see my collection of early optical instruments
used in the chemical laboratory. The collection consist of old
instruments such as spectroscopes, refractometers, polarimeters,
goniometers, and microscopes.
These instruments were designed specifically for making measurements
on or doing experiments with chemical substances. The instruments
date from the late 19th to the early 20th century.
Elsewhere
on this web site, you can see my more extensive collection of
antique brass microscopes dating from the end of the 18th to the
beginning of the 20th century. I am always interested in acquiring
new scientific instruments for these collections and will answer all
inquiries.
