Abstract

Here we describe a high-performance imaging system for creating high-resolution images of whole insect drawers. All components of the system are industrial standard and can be adapted to meet the specific needs of entomological collections. A controlling unit allows the setting of imaging area (drawer size), step distance between individual images, number of images, image resolution, and shooting sequence order through a set of parameters. The system is highly configurable and can be used with a wide range of different optical hardware and image processing software.

Highlights

  • Natural history collections are nature’s treasure houses

  • About 80 million objects are deposited in German natural history collections alone, including about 65 million insects (Brake and Lampe 2004)

  • The material deposited in natural history collections like the ZSM is principally held and intended to support research purposes
