Hi,
   I've been using my diy crt projector for about 6 months now.

I'm using a 42cm fresnel lens,first image mirror and have a silver
pvc screen painted white.

I find that watching some movies the quality of image is perfect and
it's just as good as in the movie theatre (eg Matrix
trilogy,Underworld,Terminator 1-3)whilst other movies and tv shows
the quality is pretty good and enjoyable to watch.

Music clips also look excellent.

Dark scenes in films that are lit with artificial light show up
better than daytime scenes shot in natural sunlight.

I wonder if crt tv's reduce their light emission with daytime scenes
or if it's something to do with the exposure at the filming source.

Has anyone else noticed this with their projectors?

Sorry for my bad english : i don't buy but I sell my lens on ebay...

P. Robin

Bought several years, it seems to be a lens used for the first
retroprojector during seventees.

Diameter : 6,5 inchs.

The adress if somebody is interrested :
http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&rd=1&item=130173105502&ssPageName=S\
TRK:MESE:IT&ih=003


Best regards...
P. Robin

Is it possible to buy a fresnel lens locally, and does the fresnel
lens have to be the same size as the screen on the tv that is being
used?  Thanks.

Scott

Hey,

A local shop has a set of condenser lenses that are mounted together
convex to convex. They're pretty big, like 7inches diam, maybe more.

Just wondering if these condenser lenses from enlargers work and if
so, how well?

will they work together or will I need to split them?

Any help will be much appreciated

Andy

Hi dear rined,

 

Polished land coated Multi element lenses might not have tolerated this Hard Nursing !

 

"wiped the inside lense, waited for it all to dry, and then added the
New coolent, put the housing all back togeather, nuts/bolts etc etc
etc, no leaks, and reinstalled in to tv...

I did this to each CRT Red, Green, Blue, Blue was the worse, had a
lot of bug's and crud in there look liked plack, had to realy give it
a hard clean and wipe out and flushed it 3 or 4 times....
anyhow, reinstalled the crt's, and hooked up all the wires screwed
everything back in place, all is good..."

turned the tv on, re focused the R, G, B by covering 2 crt's while
working on the one so i can focus the single crt and then moving on
to the next crt......... . did all 3 crt's...... all is good...

I am hoping that someone out here can help, I have a magnavox 56 inch
rear screen projection (RSP), crt of couse, I had the pleshures of

The picture is now clear insted of pink being white and the blue I
can now see in focus, before, blue would not focus at all, all is
good and brighter better...

The problem that I have noticed, if you look at the picture all is
clear and bright, but on the bottom right and left there are like
dream state distortions like extra flare outs of lines, r, g, b
I did the conengencts X and all is lined up niceley and no flare outs
in that setting....

The picture dispite the flear outs is very crisp compered to what it
was like.... so yes it was worth the hassel and 28 bux for new
coolant and shipping was also on back order... it arrived on sat...

anyway.........

I am thinking that when I pulled out the crt's I must have bumped
the... I think they are called yokes, or Tabs? around the back of the
neck of the crt tube, the small plates that you can move on the back
of the crt neck... I am wondering if I have bumped them some how when
taking them out or reinstalling the crt's and this is why I am
getting lower flare outs at the bottom of the screen?

Q, How can I correct this, is there a procudre to do so?

I realy don't want to stick my hand in the back of the tv, while it
is powered on, and try and grab that small tab that is located on the
end of the neck near all that high techen voltage and move it around;

... Is there a safer way to do this?

Any Help or words of wizdom???

I will try and upload some pictures that I took of the crt's and what
the picture is showing the lower flare outs. I will see if I can make
a folder named K4eeZ, that is my Amature Radio call Sign and put all
the pictures in there.

thank you all in advance for any help!

Hi,
   I recently bought a Teac tv second hand to use for my projector and
needed to access its service settings to increase the brightness and
contrast.

   I found this website and it may be of use to some people, as it has
the service manuals for most tv brands and the manuals should also
show you how to access the tv service settings.

http://www.eserviceinfo.com/equipment_type/TV_2.html

still gettin new members tho...

I undertand that all lenses must be diaphramed except a triplet.

I ask first starting with a 115mm diameter positive meniscus how much
diaphraming is aceptable before the 6 foot wide image is too dark to
watch in a dark room?

Second lets assume the 115mm meniscus will get diaphramed to 90mm for
a decent image. Does this mean your 100mm diameter triplet will be
brighter then a 115mm meniscus?

Ok. Im confused why the files in this forum recomend fresnel lenses as
last resort for choice if you are claiming better results then with
PMN lens?
Also many have acomplished very good results with PMN lens why arent you?

You mentioned that with the fresnel setup you require a diaphram but
is this diaphram not cut more light then a 120mm diameter PMN lens?
Is seems like you are saying using the fresnel method results in
brighter image compared do pcx, triplet or PMN lenses.
however if both use the same size diaphram i dont see the logic here.

So how does one get your fresnel building guide? How much is required
to spend to build the box?

Ok. Im confused why the files in this forum recomend fresnel lenses as
last resort for choice if you are claiming better results then with
PMN lens?
Also many have acomplished very good results with PMN lens why arent you?

You mentioned that with the fresnel setup you require a diaphram but
is this diaphram not cut more light then a 120mm diameter PMN lens?
Is seems like you are saying using the fresnel method results in
brighter image compared do pcx, triplet or PMN lenses.
however if both use the same size diaphram i dont see the logic here.

So how does one get your fresnel building guide? How much is required
to spend to build the box?

Also, I would say its fair to say a 500mm distance from the tv also
has less then 1.5 times less light hitting the fresnel compared to a
330mm fresnel. I understand the fresnel is 40cm wide but since light
is not parralel leaving the crt tube i am sure plenty of light is
bypassing the fresnel at 500mm distance. I assume you have done this
type of testing so please confirm or correct me.

Thanks for your quick reply. So are you saying that the reason
standard ebay fresnels give blurred corners mostly because the FL is
too short?

So I guess you are saying with this 500mm FL fresnel you are getting
good focus all across the screen of a curved tv? Can you confirm?
Also have you compared your fresnel setup to a Positive Meniscus lens
setup with at least 100mm diameter?

Also, I would say its fair to say a 500mm distance from the tv also
has less then 1.5 times less light hitting the fresnel compared to a
330mm fresnel. I understand the fresnel is 40cm wide but since light
is not parralel leaving the crt tube i am sure plenty of light is
bypassing the fresnel at 500mm distance. I assume you have done this
type of testing so please confirm or correct me.

Thanks for your quick reply. So are you saying that the reason
standard ebay fresnels give blurred corners mostly because the FL is
too short?

So I guess you are saying with this 500mm FL fresnel you are getting
good focus all across the screen of a curved tv? Can you confirm?
Also have you compared your fresnel setup to a Positive Meniscus lens
setup with at least 100mm diameter?

Is the photo result on your website that of a normal curved 15 inch tv

Same question as here: http://www.lumenlab.com/forums/index.php?
showtopic=19997

If you don't know, I'm pretty sure the focal length of the fresnel (I
don't think it's usually used in the CRT projectors here, but I'm gonna
experiment and see how much improvement I get) is supposed to be
slightly less than the projection lens, so the focal point can be right
before it goes into the lens, and then all of the light emitted from
the CRT is projected.

The Lumenlab trading post has two Bessler triplets one for shipping and
handling only http://www.lumenlab.com/forums/index.php?showtopic=19694.

i am going to try to make my own projector in the next couple of weeks
or so but dont know what lens is good to buy.
i was searching on the surplus shed website and found this lens
http://www.surplusshed.com/pages/item/l3806.html is this the right lens.
if not can anyone tell me where to get a good lens for cheap.

thanks,
charlie

Remy

Apologies..there is something wrong with Yahoo...the last post from me
was supposed to be the first and only post...it went AWOL for hours
..so I reposted ..and now LOL it's turned up !

I can only imagine that this post that went AWOL went to a different
server...a slow server before it finally posted here.

Remy as you can read it's the same so please just ignore as like you
said you have already answered the questions.

Cheers


So Please MODS/ADMIN please delete to stop the confusion
