Up for sale is a complete Rochester Cloak lens set originally supplied by Surplus Shed for building the famous Rochester University-inspired optical cloaking experiment.

Included are all pictured components:

  • (2) F1 achromatic lenses
  • (2) F2 double achromatic lenses
  • Original Surplus Shed Rochester Cloak instruction sheet
  • Original storage wrappers and packaging shown
  • Lens retaining rings/spacers included as pictured

This lens configuration is based on the well-known Rochester Cloak optical design that demonstrates a real cloaking effect using conventional lenses. When properly spaced according to the included instructions, objects placed within the cloaking region become significantly less visible to an observer looking through the optical system.

The set was acquired from the scientific optics collection of physicist Glen Jolly and has been preserved in its original packaging. Glass appears clean with no obvious chips or cracks observed during inspection. Please examine all photographs carefully as they form part of the description.
