I found a set of lenses in subject.
They appear in good condition and I think that are fully compatible with original barco's supports.

Which is the just price for these set?

Thank you

I've thrown out two sets for total lack of interest, so they should be pretty cheap...

The 24s are hard to find. They will focus on large screens. I focused a set on my 10' wide screen with no problem. The 12s are easy to find but only focus on very small screens. But they are not a lens with a lot of interest so they should be almost nothing.

... the seller ask 540 dollars for a set

if I wasn't already moding hd-18's for my 808 id be trying to find these lenses also!!

I have been pondering replacing my runco 933 with my 808 that I have done a lc conversion on. Do you guys know how close the focusing of the 145s are to the 117-12's?

[papalek]

The 12's will only do really small screens.

Can I use HD117-24 lenses with Sony G70 C-elements?

Hello from Munich,

I have bought one set of the 24´s a year ago, to convert my RVP4010 to fp. But until now I only swapped to the hd215 lenses, because I did not had to change the elements. But I also have the Barco elements here. I have never changed elements, but I will have to, because I want to build a curved screen. But I don´t know how much curve the 24´s can handle. Thats why I also bought the G70 elements, to use them wit the HD18/134 lenses for curve. But I still have to buy the HD18/134.
But I know and love the throw distance of the 24´s. CRT screen distance is the same as screen width, I was told! So great if I would stay on a flat screen. Here in Europe the 24´s are rare like hen´s teeth, because many peaple want to convert Retrographics 808s to fp, or swap the tubes for a LC conersion of a fp machine. But sounds like I was lucky: Seller asked for 180 Euros, and I offered less and receives them. But I was searching one year!


Best regards

I am waiting a set of these lenses bought from a very kind user of this forum (thank you Jörg)
I hope that they are compatible for my color corrected G70 c-elements, otherwise I will swap them with the original Barco c-elements (but they are clear).

Sto aspettando una terna di queste lenti acquistata da un utente molto gentile di questo forum (grazie Jörg)
Spero che siano compatibili con i miei c-element colorati provenienti da un G70, altrimenti li cambiero' con i c-element originali Barco (che pero' sono chiari).

The set of lenses just arrived.
Watching them I have now a big doubt: the rear lens is concave
It would not have to be convex like in my HD18 set?

Le lenti sono appena arrivate.
Guardandole ora ho un grande dubbio: la lente posteriore e' concava
Non dovrebbe essere convessa come nelle mie HD18?

I think color filtered 8" c-elements (same for HD-18, HD-134 and HD-215) have different radius for concave than Barco 8" c-element (HD117), so those probably aren't working correct when mixed.

Yes I have both and I'm sure that circumference is the same because I swapped c-elements when I maked LC conversion.
I hope next week to compare concavity.
