Field Botany and Entomology
A high-quality magnifier is essential for field study in many of the natural sciences. Botanists and plant pathologists will find a relatively high-power glass such as the D16-AR ideal for evaluating leaf, flower, and seed structures, and identifying molds and other pathological agents in crops. And a lightweight multi-lens pocket loupe like the Zeiss D12+24 which provides 3, 6, and 9 power viewing, is a handy versatile companion for every type of scientific field work... from mineralogy to paleontology, entomology to herpetology, and just about every 'ology in between.
