Small Microscope

Originally created while researching basic microscopes for McMaster SCA/FI workstation. These need to see a rough idea of a die position, but not resolve individual transistors. Goals were:

• Light enough to mount on 3018 Pro CNC Z axis
• Compact => not get in the way of other tools such as laser
• Relatively inexpensive (no more than $300?)

USB microscope

Dino-Lite

These are the most common professional option in this category. Common models appear to be the AM2111 (basic, ~$100) and AM3111 (more LEDs, variable brightness, $150). However they have relatively low resolution (0.3 MP)

McMaster: ordered "Dino-Lite Premier2 1280x1024 USB Microscope AD-4013MT" for $300 on eBay. With a 1.3 MP camera I'm hoping this will produce a pretty decent image.

Modular tube

These can be used to make custom microscope assemblies. Some of these support epi illumination as well as ring illumination.
