Antique Direct Vision Spectroscope by Nachet of Paris c1900

A fully functioning direct vision spectroscope by Camille Nachet of Paris in its original shagreen tube style case. The scientific method is after a design by Browning of London with alternating 3 flint glass prisms with 2 crown glass prisms. This pocket-sized spectroscope was often used to detect the Rainband a spectral effect that can be seen before impending rain. Handy if you are off in the country without a brolly.

Camille Sebastien Nachet was a Parisian optician at the beginning of the 19th Century. He began producing lenses for the famous microscope manufacturer Chevalier but later set up his own small business at 16 Rue Serpente, Paris. He was succeeded by his son Jean Alfred 1831-1908. Nachet is included with Chevalier and Oberhauser as the three leading optical instrument makers in Paris at this time.

Antique French Microscope [Probably Nachet – see Billings Collection] – c1860

A nice mid 19thC microscope with original box. Likely by the French maker Nachet of Paris. Everything including the original lacquer in very good condition. Functioning well.

Similar if not identical to the Billings Collection Fig 125, page 67. Billings states makers unknown but suggests Nachet or Hartnack both of Paris and circa 1860’s. Also, see online “History of the Microscope” which shows three examples of which this is the larger of the three – they reference English maker J.H. steward as making something similar but recognise a French maker re this specific style.

The microscope arises from a painted green and gold-toned weighted foot via a ball and socket joint to the bottom of the pillar. A small knob on the foot adjusts the tension on the ball and socket joint to allow the user to lock the position of inclination. The single sided gimbaled mirror is attached to the pillar via a pin. Focusing of the main tube is by a knurled knob acting on the rack and pinion. On the tube a ring carries a two-jointed arm with a bullseye condenser. The objective “French” double button type; compounding. Beneath the stage is a revolving disc of diaphragms, above the stage a casing with a lyre-shaped stage clip. Stands circa eleven inches closed. The original box retains its original sections, has some cracks and age about it but authentic and has kept the microscope in very good condition.

Postage will require a supplement dependent on location of buyer. Please enquire.

Camille Sebastien Nachet was a Parisian optician at the beginning of the 19th Century. He began producing lenses for the famous microscope manufacturer Chevalier but later set up his own small business at 16 Rue Serpente, Paris. He produced his first instruments based on the drum- type base models made previously by other manufacturers. He was succeeded by his son Jean Alfred 1831-1908. Nachet is included with Chevalier and Oberhauser as the three leading makers in Paris at this time.

Rare Large Sized Microscope Size – Lantern Fly – China

No date or maker but this presentation was a specialty in the late Victorian / Edwardian era. Reference authority “Bracegirdle” shows a number of “outsized” examples but none quite like this.

In modern terms known as the spotted lantern fly. The insect is on the move and a potential threat in Australia – modelling has shown that it could survive well in western and north-western Victoria. When we say a threat, it was endemic to China and Vietnam but moved into South Korea in 2006, Japan in 2009 and the USA in 2014 … so the move is on.

Here the little blighter is beautifully preserved and presented in Canada Balsam … we know that CB was the mounters choice due its quality and the cursive narrative says so.

A microscopical rarity outsized mount of the Spotted Lantern Fly.
