Description

Brücke achromatic magnifying glass with engraved linear reticle

19th-century portable scientific instrument

Used in ophthalmology, surgery, dissection, histology, botany and mineralogy

Foldable brass scientific magnifying glass, Brücke type, equipped with achromatic optics and a linear reticle engraved directly into the glass.

The reticle, composed of superimposed parallel lines forming a scale, allows for comparative observation and dimensional estimation of fine structures.

The instrument unfolds using sliding tubes.

The eyepiece is made of black-painted brass, characteristic of scientific laboratory instruments from the second half of the 19th century.

Carefully crafted, with no visible markings.

Used in histology, botany, mineralogy and physiology, this magnifying glass was used for rapid examination and relative measurement of fibres, striations, veins and other structures, often in conjunction with a microscope.

Material: brass

Optics: achromatic to avoid aberrations due to magnification

Reticle: linear scale engraved in the glass

Mechanism: foldable with telescopic tubes

Condition: good antique condition, patina from use

Circa 1860–1890

Authentic 19th-century scientific instrument, somewhere between an achromatic magnifying glass and an optical measuring tool.
