For Sale
Status: Sale Pending  Advert Category: Optics-Lens  Advert # 128804
Vintage J H Dallmeyer Objective Lenses
Post paid in UK.

Quality lenses from one of Britain's most important optical maker.

Each of these lenses is mounted in a cell engraved with the maker’s name and a serial number. From the condition I'd assume that none has ever been used.

1. A set of FOUR lenses, with a blueprint, giving specifications. The cell is possibly brass in view of the weight. Each one is stated to have a focal length of 12”. There are two 2” lenses, a singlet and a cemented doublet; and two 1.5” lenses, again a singlet and a cemented doublet. The 2” doublet has bubbling in the cement around the edge. The two singlets are in A1 condition; I can’t really examine the 1.5” doublet : it’s still sealed in its original bag!

2. A cemented doublet of 60mm aperture and 12” focus. The cell is threaded to rear. Cell in excellent condition; some cement issues at periphery of lens.

3. A cemented doublet of 60mm aperture and 18” focus. The cell is threaded to rear. Excellent condition, and unmarked glass.
