- Carl Zeiss Jena Deltrintem 8x30 Binoculars Serial Numbers
It happens very often that a set of binoculars touted by its seller as being “in perfect condition” can be hardly described as such. This bad practice is notoriously common. Anyway if you decide to buy something on the second hand market you must give it your full attention – otherwise you might end up sending your bargain purchase to an optics specialists and paying extra money for repair or cleaning.
From the Lens Collector's Vade Mecum: (a) Classic Zeiss Jena numbers. It does seem that very low numbers do exist, and it is suggested that they begin at Jena at 1,000 in about 1890, unless information to the contrary is found.
I check auction sites regularly for older Zeiss Porros. With the information from that means they were produced between 1928-1929 if I understand the serial carl zeiss jenoptem serial number concept. Jenoptfm guide is in response to the number of fake or non-genuine Carl Zeiss binoculars being sold on E-bay. The Kenoptem site has a recent review of the 8x30 DEltrintem, the kid carl zeiss jenoptem serial number to these.
Can anybody tell me a website where I can check the serial numbers for Carl Zeiss Binoculars. Is a Deltrintem. Of Carl Zeiss Jena 6X30 with serial.
4.1/5.0 Tripod Lack of tripod exit. In our 8x32 binoculars test we granted all the instruments the average mark of 1.5 points as in the case of the equipment of this class a tripod adapter is rarely used. 1.5/3.0 Interpupilary distance from 47.3 to 76mm 6/6.0 Closest focusing distance 1.9 m 1.5/2.0 Eyepieces FOV Apparent field of view of 67.5 degrees.
The colour fidelity can be a problem, though. In the 80s of 20th century the coatings were already multi-layered but still optimized only for the centre of visual spectrum. It had the effect which can be witnessed here - the transmission for yellow light is high but for blue and red it becomes even by 20% worse. As a result the image is seriously yellow. As we’ve already passed to disadvantages, we must also mention the other negative points. The edge of the field of view, which is not sharp enough, and noticeable distortion can be certainly counted among them. What’s more, the usage of such wide-angle eyepieces made the exit pupils distinctly truncated.
The silver streak in the box is etched out, not paint. The text in the center hinge washer(?) says 'GERMANY' just above the screw. Nothing else I can detect.
What’s interesting, at first a number of Deltrintems, released on the market, had the Carl Zeiss Jena logo on the one side and the Docter Optic on the other. With time the binoculars offered by Docter got completely new and much more efficient antirelection multilayer coatings which improved their optical properties in a significant way.
It is tentative in places.!890 Anastigmat production begins. This is partly licensed to others, including Voigtlaender for Germany.The earliest Zeiss Anastigmat noted so far is No1,51x suggesting a possible No1000 start at Jena for camera lenses: but note an aplanat for projection seems anomalous. 1895 Voigtlaender stops production of Zeiss designs, suggesting Zeiss had expanded production facilities to make the lenses at Jena. 44,040 as Unar sales begin, production of anastigmats reaches 100,000, with about 44,000 by Zeiss and 56,000 under license.
2.3/5.0 Housing A classic Porro set of binoculars with an ocular bridge. Comfortable to hold.
Two listings then exist, and run very much in parallel. Gilbert, in 'Collecting Photographica' and is reproduced in the back of McKeown's 'Price Guide'. The other is given in 'Chiffres Cles' by P-H.
There were no antireflectiion coatings so fewer air-to-glass surfaces meant higher transmission. The original optical construction of 8x30 models featured as many as 10 air-to-glass surfaces. Taking into account losses of light on every surface amounting to about 4.5% the transmission of the whole system didn’t exceed 63%.In reality it was significantly lower than that because the light absorption in older types of glass was higher, especially when it comes to blue light. The real transmission values of 6x30 and 8x30 binoculars produced before II WW reached just 40-50%. 4-element Koenig eyepiece, from Deltrentis and Deltrintem models produced in 1920-1947. The original Koenig construction was presented in 1915 and consisted of three elements (2+1). It provided a well-corrected field of view of 55 degrees and a quite comfortable eye relief for those times.

During the WWII one layer of magnesium fluoride coating was put on air-to-glass surfaces. In 1947 the ocular was replaced by an Erfle design with 5 lens-elements which was supposed to provide a wide field of view with minimum distortion level. In 1978 the producer started to use new multilayer coatings with the characteristic orange-purple hue.
Also some slight design modifications were introduced (e.g. Rubber eyecups in the 8x30 and the 7x50 models). X-ray photo of the Carl Zeiss Jena Deltrintem 8x30 binpculars. The last specimens of the Docter Optic Classic 8x30 were produced in 1995. That year Bernhard Docter went bankrupt and the company decreased its production looking for a potential buyer. In 1997 they were bought by the Analytik Jena GmbH but it is a material for another story. A page from the Docter Optic catalogue with the Classic series binoculars.
There are some specks of dust on the prisms but it is quite understandable taking into account the age of the device. Its condition places the workmanship quality in a very favourable light – after next twenty five years the Deltrintem 8x30, tested here, will look still the same, providing it is used in a similar way of course.

Instruments which have been stored and used in different conditions for 25 years can differ slightly when it comes to the oxidizing of the coatings. A difference between particular specimen can be also a factor here – the binoculars from Jena were really mass-produced goods after all. Of course measurement errors could also add to that but their influence is most probably the smallest. The right colour rendition can be a problem, though, for Jenoptem and Deltrintem and other binoculars from Jena as well. In the 80s of 20th century the coatings were already multi-layered but still optimized only for the centre of visual spectrum.
The text in the center hinge washer(?) says 'GERMANY' just above the screw. Nothing else I can detect. Thanks for any insight.
First of all, Hensoldt had already collected much experience with their Dialyt roof-prism series, during and even before the war times. Then, Zeiss had just finished the construction of its superb Porro binocular (Fig. 4) which had got the advantage of being more compact and of superior optical design.

The 8X30 Deltrintem and 8X30 Jenoptem were identical in and specs, the only difference being manufacturing techniques automated production with carl zeiss jenoptem serial number Jenoptems used, eerial the Jenoptem as less expensive, but not necessarily lesser in quality.

This guide is in response to the varl of fake or non-genuine Carl Zeiss binoculars being sold on E-bay. Fakes are always marked as multicoated. To be specific DDR Carl Zeiss Jena multi-coated Jenoptem 8x30w binos. You are most welcome to for an account, which allows you take part in lively discussions in the forum, post your pictures in the gallery and more. These were sold mainly from mail order catalogues in Britain in the late carl zeiss jenoptem serial number to early 80s.
The 8x30 remained in production until 1971, and the 8x30B stayed around until 1978. 5: The Leitz 8x30 Binuxit (serial no. 617222, about 1950s) The Leitz Binuxit was introduced as early as 1927 and remained in production until 1962, when it was replaced with the 8x32 Trinovid roof prism. During war times, light weight versions were available for the military. War production stopped around serial no. So that the sample on the picture was probably made sometimes during the 1950s. Its external appearance definitely resembles the Zeiss Deltrintem, but it is of entirely independent optical design.
The specimen, tested by us, had the serial number of 6173583, which means it was produced in 1985. The binoculars feature the newer multi-coatings then. In the set with the binoculars you get a thin strap and a small soft case.
In 1978 the producer started to use new multilayer coatings with the characteristic orange-purple hue. Around 1990 when the Jena plant was taken over by the Docter company, the binoculars not only didn’t go out of production but even were given improved multi-coatings. Its production, already under the Doctor brand name, ceased only ca.1995.
The lenses have got the typical single layer coating of that generation, but it appears that the prisms remained uncoated. This binocular is the oldest among the seven competitors, but despite of its age it is still in excellent condition, both mechanically and optically - surely a demonstration of Leitz's high quality production standards. 6: The Hensoldt DF, here with partial armor (serial no. 61714, about 1960s) The Hensoldt Diagon was introduced in 1948, it was the center focusing civilian version of the 8x30 binocular which would later become the standard binocular of the German army (Bundeswehr). The military version, the 8x30 DF with individual eyepiece focuser and a partial rubber armor, was introduced in 1955, and by 1960 the full rubber armor was available. The device in this picture belongs to the latter series, I have removed parts of the rubber so that the imprints on the prism house become readable. It is not immediately clear why this binocular had been chosen for the army, since alternatives were available in 1955.

These binocs are a great buy when in good condition. They still are excellent optics. Note that there was a thriving business making 7x50 replicas, but nobody built fake Zeiss 8x30s, to my knowledge Hi, Just got a pair of Carl Zeiss Jena 6X30 with serial number 1484950.
