Well...

Am primit un raspuns din partea lui Robert Sach de la Cargille, foarte prompt si la obiect: 

"Dear Mihai -
 
Thank you for your inquiry.  I believe that the nomenclature that Mr. Sigler used is the same as is used with Optical Glass.  His liquid code 400513 I believe is our Refractive Index Liquid Series AA n = 1.4000.  His liquid code 550206 is our Refractive Index Liquid Series E n = 1.5500.  Please see the attached Typical Characteristics Sheets.  You can order these liquids as follows:
 
Catalog # 1806Y Refractive Index Liquid Series AA n = 1.4000 +/- 0.0002 @ 5893A at 25'C
1 fl. oz. ....................$62.00
 
Catalog # 1843Y Refractive Index Liquid Series E n = 1.5500 +/- 0.0005 @ 5893A at 25'C
1 fl. oz. ....................$111.00
 
Please let me know if you have any further questions.
 
I would suggest that you download the order form from our website, www.cargille.com, complete all of the required information, including your credit card and shipping information, and fax this form to us at (973) 239-6096.

Best wishes -

Bob"

Din matrialele trimise de la Cargille rezulta o stabilitate foarte buna, nefiind detectate schimbari in proprietatile optice ale celor 2 lichide dupa 10 ani de expunere la soare.  

Acum problema sticlei.

Dupa ce toata ziua am trimis mail-uri la mai toti producatorii de sticle optice despre care am gasit informatii cat de cat utilizabile ex: Newport Glass, Schott, Naked Optics si altii, am gasit cateva PDF-uri cu preturi estimative pe care l-e aveti atasate mai jos. 

Arbitrar am ales un diametru de 140mm si o grosime de 25mm pentru blank-uri: 2 x BAK2 si 1 x SF2

Rezumat: 

Lichide speciale:

Sigler 1991                        Cargille
400513                              AA n 1.4000              30cc - 62$
550206                              E n 1.5500                30cc - 111$

Total estimativ - 173$

Sticle

          Diametru    Grosime   Densitate  Nr  Greutate totala  Pret     Volum

BaK2  140mm       25mm      2.86g/cc    2   2196g             21$/Lbs 1098g

SF2    140mm        25mm     3.86g/cc    1    1482g            21$/Lbs  1482g

(Dupa cum puteti vedea in atasamentele de mai jos, pretul sticlelor variaza intre 4.40 - 100$/Kg pentru BaK2 si 6.30 - 100$/Kg pentru SF2)

BaK2 - 100.8$
SF2 - 69.3$

Total estimativ - 170.1$

TOTAL COST MATERIALE - 343$

In momentul de fata adevarata problema o reprezinta totusi costul sticlei, cel putin pana primesc un reaspuns.
