Zeiss 100w Halogen bulbs

[75RR]

.
Anyone have an original 100w bulb 380059‐1660‐000 with box for the illuminator 100 ?

Interested if there are any UV and/or IR warnings on it

These are some I picked up a while ago (they are meant to be equivalent replacements) but have not used yet. Seems to warn about everything!

Zeiss never made those bulbs by themself. They labeled Osram bulbs. You will find the information required on the Osram website. Yes, it produces some UV but by far not enough to create any risk as long as you don't place it directly on your eye. Walking in day light is a much stronger exposure to UV. Like any other halogen bulb it produces an quite significant amount of IR. This is why those lamp houses came with heat filters.

I have both Osram and Ushio 100 watt bulbs here but Krypton type and there are no such warnings. HLX means that Xenon gas has been used in the bulb, an Osram technology called Xenophot. Normally Krypton is used. Xenon is supposed to allow for a higher burn temperature, so perhaps there is more UV and IR. I also have another brand with no warnings but it claims to use UV block technology. No other warnings.
HLX 64623 is a 2000 HR. bulb that has a lot of general purpose uses in various medical devices. The 50 HR. version, HLX 64625s I have here, just have a warning for hot.
Some countries might have very strict guidelines about such warnings too.

Thanks Alexander and apochronaut,

afraid not much info on the Data Sheet (copy paste link below in browser)

Can anyone translate these symbols

If you have one of the Illuminator 100 lamphouses can you point out the heat filter for me.

Only glass between the bulb and the microscope that I can see is the focusing lens.

I should have been more precise.

Leitz Lamp houses for 100 W and up always had filter slots. Zeiss didn't have them. You could easily grill a specimen by using a 100 W bulb for translucent bright field work on a Zeiss scope. Just do proper Kohler.

100 W are rarely used für translucent bright field. Much too bright for that. A more typical use is epi-Illumination and fluorescence (blue excitation) work. Epi-illuminators have heat filters build in.

[Wes]

Newer Zeiss lamphouses have a heat blocking filter which you can spot by its red reflective tint. Older ones (like the ones me and 75' use) don't have it.



There is a KG1 (IR blocking) filter in the base of some of the large research scopes (Universal, Phomi).

Here's an older Leitz lamp I converted from a 100W halogen to 55W Xenon, I removed the filter since the heat that the Xenon puts out is minimal compared to the 100W Halogen, also the ( car) Xenon bulb glass cover that Im using already filters out enough UV so didn't want to add with the filter .

Can anyone translate these symbols
.

Left = Don’t look directly at the lamp, there is an eye-safety hazard
Right = Not suitable for room lighting

or words to that effect

One is, " not for household use" The other is a bit strange. There must be a problem with baby European Vipers taking advantage of the warmth in the lamphouse or just even the security of the bulb packing box in Germany. That appears to be a warning along the lines of "beware of nesting baby snakes biting you in the eye".

The other possibility is " beware of staring straight at the lamp filament or beam".

Thanks Alexander, Wes, Plasmid and MichaelG.

re-Left: Badly drawn medical symbol? Hardly intuitive though.

Hazard mostly IR I take it? Solvable with a Schott KG1...

Sorry, concurrent posting - does look like a lamp filament!

I am all for helping hard up relatives out, but this is silly!

That is my assumption … but I was disappointed to find no easily accessible ‘key’ to these icons when I looked earlier

Surely this stuff is the very essence of what the folks in Brussels are supposed to do

I would try a KG3 filter first. It is thicker than the KG1 hence it blocks more IR. These are absorpion filters, so transparency to IR depends on the thickness.
The medicine symbol is not so bad if the snake is not a viper and its head is not the (scary) wide triangular form.

All filters in link are 2mm thick ...?

Maybe the symbol is telling you to look upon the brazen serpent to cure your snake bites

Sorry, seems my memory failed me about this. I stand corrected. They could be had within a range of thicknesses.

Still, from personal experience with 100W (high pressure) lamps, I would prefer a KG3 or even KG5 if available. The data tables show that T% at 800nm of the KG3 and KG1 are ~0.3 and ~0.1, respectively, for the same 2mm thickness.

I'd make a guess and say seek medical attention if you have been staring at the bulb

I have just sent the following request to OSRAM :

Dear Sirs,

There is a discussion currently ongoing on the ‘microbehunter’ forum, concerning the pictograms on the box containing your
64623 HLX lamp.
I find it extremely worrying that no-one in the group has been able to find definitive interpretations of these graphic symbols.

Could you please advise ?

If you can provide a link to an explanatory document then I would be very happy to post it on the forum as a helpful guide to safe usage.

Many thanks in anticipation of your kind assistance.

interesting thread...thanks for all the useful info. I am curious about a couple of things (from ignorance). I do mostly work with DIC and was wondering if the combination of the polarizing filter and all of the prism combinations have an impact on the amount of IR that would be transmitted. A bright light source is needed for DIC so the 100W Zeiss lamp on my PM3 is needed, especially at higher magnifications. Do the heat blocking filters mentioned in some of the posts reduce the amount of light that is transmitted?

Dear Michael,

I'm happy to answer your question. The two pictograms are not safety-relevant symbols in terms of their shape. Prohibitions or warnings are usually shown in a triangular symbol, instructions in a circle and general information in a rectangle. There is a reasonably suitable European regulation on this (EN ISO 7010).
The symbol with the rod of Asclepius and the eye indicates the intended use of the lamp, as required by Directives 2019/2015/EU and 2019/2020/EU. In this case, it is a special lamp for medical optical imaging. There is no pictogram predefined by the directive.
The crossed-out house symbol indicates that this special lamp must not be used for household applications. This symbol is also an information requirement resulting from the Single Lighting Regulation mentioned above. Following an interpretation of Lighting Europe (Guideline to SLR V4), the symbol even states that the lamp must not be used for any other purpose than the one stated. The opinion of our customers is very important to us and we thank you for the advice regarding pictograms that are difficult to understand. We will check whether an adjustment is necessary at this point.

Best Regards

[MichaelG.]

Many thanks for the explanation, ‘Phosphorous’

I did send follow-up message to Osram, on 01-December
… Would I be correct in assuming that you have seen that, and posted as their representative ?

I greatly appreciate your advice on the matter …Thanks again.

Yes, we received the request via the global contact form and I was asked to comment on the issue.

P.S. __ I think the most important takeaway from your very helpful response is this explanatory note:

The symbol with the rod of Asclepius and the eye indicates the intended use of the lamp, as required by Directives 2019/2015/EU and 2019/2020/EU. In this case, it is a special lamp for medical optical imaging. There is no pictogram predefined by the directive.
