Description

Floroscope - Brass insectoscope - pocket microscope

These small microscopes, also known as Floroscopes or botanist's microscopes, were sold in France from the 1850s to the 1930s.

These small pocket microscopes, made of brass and glass lenses, enabled rapid observation of insects, small minerals, flowers etc. in nature.

Warning: These small microscopes usually consist of two different parts, but this is not the case here. The floroscope consists of two identical systems: two Stanhope lenses.

It is used for magnifications greater than ten times. The Stanhope lens is very rudimentary, consisting of a cube, prism or cone made of glass with a flat surface.

I suppose that the single lens with its original cage must have been lost and replaced by a second Stanhope lens...

Late 19th - early 20th century

Perfect for any self-respecting budding entomologist!

Height: 5.5cm Diameter: 2.5cm
