EXPERIMENTERS MULTI-ELEMENT LENS ASSEMBLY
We don't have a clue what this was originally designed
for, but you can use it as is as an objective lens, or take
it apart to get six different lens elements, positive and
negative between 30 and 40mm diameter. As is, the
focal length is about 9 inches and gives a nice clear,
sharp color corrected image with an eyepiece. One of
the lens elements has what appears to be a strong
dichroic coating reflecting red on the coated side. There is a lever that
when turned moves a group of lenses up and down the barrel, but it doesn't
appear to effect the focal length. Barrel is 55mm diameter by 60mm long.
Clearly a quality piece. If you can figure out what it was made for, you
might be able to re-sell them at a profit. Unused.
L3338 $7.50
FUJI MIRRORED COPIER LENS 187MM FL, EYE/FACE INSPECTION?
Unused with front and rear covers. Front element has
a 55mm clear diameter. Mirrored lens easily unscrews
from the back. It's a 40mm diameter negative lens
with the rear center 20mm aluminized. The focal
length is perfect for viewing your eye, nose, teeth, etc.
Assembly is 77mm diameter by 45mm long with a
flange 90mm diameter.

MTD 25MM FUJINON COPY LENS, 170MM FL
Quality coated multi-element optics made by Fujinon,
Model CP. Clear front and rear lens elements are
25mm diameter. Plastic housing is 100mm long by
24mm wide. Has two mounting holes. This would be
great for a small compact finderscope as the images
with an eyepiece are sharp and color corrected. Also
makes a great 2X wide field magnifier with a sharp,
flat color corrected image edge to edge and nice working distance of about
120mm with a 120mm diameter view. Focal length is 170mm. Unused.
L3344 $4.50 or 10 for $35.00
MTD,CTD LENS ASSY, 20MM FL, 42X
Multi-element, coated lens assembly made in Japan.
Not sure what it was made for. Barrel is 35mm long by
21mm diameter. Focal length is 20mm. Marked "20MM
42X JAPAN". Does not work well as an eyepiece. Field
of view is very narrow for that purpose. Does well as a
sharp color corrected magnifier but not a wide field.
