Iris holder for Amazon microscope

For consumer grade microscope to unlock the power of 100x objective lense

• Iris: Amazon product: B0F83V9SF4
• Microsope: Amazon Product: B0DGCX95RC

Image shows old slide with mature azotobacter cysts with 100x objective lense and 40x camera lense. Without the iris those were just blobs.

Why?

At the objective lense 20x and above(40x, 100x), without iris, we start hitting the diffraction limits. Thus, the objective lenses are not usable unless iris is installed.

Big thanks to Grok @xAI for helping me troubleshoot the issue.
