antique
microscope,

on
the limb Abraham
& Co., Liverpool”.
This mid 19th
century (circa 1850),
monocular microscope with accessories in it's fitted
case
is similar in
style to the Society of Arts microscope but was made before the
Society offered the prize for the 3 guinea microscope. The
microscope accessories
include forceps,
eyepiece, a 1inch objective, a ¼ inch objective (both in
matching brass cans and with pre-RMS threads), old slides, and
watch glass type wet cells. The microscope
has a detachable body
tube with rack & pinion main focus, square stage with slide
bar & built-under wheel
of stops condenser
and a single sided substage concave mirror.
The mahogany
case,
which is just under 9 inches long, has brass hinges & catches.
The finish on the instrument is somewhat worn and chipped as you
might expect from a 150+ year old microscope, but is in good
working order and is a typical example of this famous maker’s
instruments -

BAKER INTERFERENCE
MICROSCOPE - A
20th
century
Interference Microscope with petrological and dark ground
facilities. The instrument has both binocular and monocular
eye sets,
quickly exchangeable single
and triple
nosepieces, three, interference objective/sub stage condenser
pairs (X10, X40 & X100) and a darkfield objective/sub stage
condenser (X100) pair. There is a plano-concave mirror plugged
into the limb beneath the sub-stage. The sub-stage has built-in
lever operated iris, filter holder and separate lever operated
polariser. Focussing the sub-stage is by rack & pinion
thumbwheel and the sub-stage has the quick change facility for
condensers. The centring/rotating stage is graduated 0 – 360
degrees and course & fine focus is by racking the whole stage
assembly. Above the nosepiece is a lever for mon/bi use by sliding
a small correcting lens into or out of the light path, a slider
with a quarter waveplate, a rotating polarising disc graduated 0 –
240 degrees with a magnifier to help read the scale. The whole
body tube assembly is removable and clamped in place with a small
lever on the right side of the body tube. The binocular eye set
rotates and inter-ocular separation is swinging out the eyepieces.
The binocular set is replaced by a monocular set by un-screwing
the ring at the top of the eyetube. As well as all the built-in
features, this microscope comes with a separate goniometer
eyepiece set
comprising 0-360
degree graduated base with lever operated iris, above which is a
sliding 6 order quartz wedge with micrometer scale and a sliding
eyepiece filter pair, with magnifier. There are also two pairs of
eyepieces (X5 & X10) for the binocular set and two monocular
eyepieces (X7.5 micrometer & a telescoping variable power).The
microscope was made by "C.BAKER,
London",
and comes in a fitted case
along with
another case of accessories.
