Modular Darkfield Filter Set for Microscopy

Bring your specimens to life with this set of 16 darkfield microscope filters, crafted for DIY microscopists, educators, and science artists alike!  Designed to fit snugly over standard 32mm condenser lenses or into stereo microscope light wells, these filters let you experiment with light and shadow to create striking darkfield illumination. 

This set includes 4 unique styles, each with 4 variations — for a total of 16 filters. Each filter has a convenient label, so you know which objective to use it with [4x, 10x, 40x, oil]:

• 🟤 Central Patch 
  • Classic darkfield stops for bold, high-contrast edges
• 🌙 Half Arc (1/2 Edge Stop)
  • Partial obstruction for directional side-lighting
• 🌘 Quarter Arc (1/4 Edge Stop)
  • Adds asymmetrical drama and depth
• 🎯 Offset Punch
  • A shifted center spot for uneven, artistic lighting

Each variation tweaks position and size for different effects — perfect for enhancing detail or creating beautiful, abstract backlighting. 🌈📸
