PHOTOGRAPHING PINNED INSECT SPECIMENS

A simple effective process in both cost and time, that requires two Led light rings, and a PVC pipe connector for the standoff backlighting.
Results
Hypochrysops theon upperside

Led Ring light, or other lighting for specimen Aputure Amaran Halo cost $80
Led Ring light or Flash for Backlighting cost $30
Vertical Rack Made from
Stage X-Y Movable Stage with 0-50 mm Scale Ruler Microscope $25
PVC storm pipe coupling 90mm cost $1.75

Small Insects and Focus stacking
Microlepidoptera examples
There are many examples of focus stacking rigs
I recommend a Horizontal System as opposed to a Vertical System to reduce the chance of damaging the specimen.
I use a Wemacro Focus Rail sliding on a Dovetail on a substantial base.

The ball jointed specimen rack can been turned to an upright position for safe mounting of the specimen, and then locked when returned to the Horozontal.

The specimen stage can be moved crosswise by a Novoflex or similar slider
Vertical up and down is done with an adapted microscope stage rack

Using Microscope lenses I use a Helical focus tube and appropriate extension tubes

Lighting of the subject is a matter of choice

Horizontal mounts of butterflies also helps minimize dust settling on them. I like to add a dust protector.

Thanks Lou,
When using the Led/Back lighting system as in the initial post ,the turnover time from entomological cabinet draw, taking a photograph and back to the drawer is about four minutes, so that problem is minimized.

Looks like one of the components of your rig are the rails from a Honeywell Repronar, which I also use in my stacking setup.

Mike,
You are correct on the Honeywell Repronar rail for the specimen movement.
The Wemaco is clamped to a short Leitz Aristophot dovetail rail with a Leitz clamp.
This combination works well,
Len
