For reference, the average human hair measures 70 microns, while a red blood cell measures eight.
That makes the Q3p an incredibly powerful optical tool.
What the Q3p crucially gains this time is a polarizer.
As with the Q2p before it, this enhances the contrast and color of images viewed through it.
Its particularly effective when it comes to viewing the structures of crystals and minerals.
Because these materials are birefringent, their visual properties depend on the direction that light travels across them.
The polarizer lets you adjust for this.
That makes it orders of magnitude more portable and less expensive than a professional desktop microscope.

The applications for a fingertip microscope are many and various.
Also available with the Q3p is a focusing stand.
