Ferretboy111 Posted January 22, 2007 Report Share Posted January 22, 2007 Keep us posted, am really intrigued to see how one could enhance the bresser nightvision that we have purchased. I emailed bresser about infared attachments, and they recommneded a kodak wratten infared gelatine filter, so am trying to hunt one of these down.

pin Posted January 22, 2007 Author Report Share Posted January 22, 2007 Well mate the difference with the thing I made already is like night and day. It really works well just doesn't shine up the eyes of little furry critters I would say the beam was going out to 400 yds, under 200 yds it was literally like daylight on anything it was pointed at. The torch itself is quite heavy and doesn't last long (25 mins) which isn't really much use. On the plus side though the beam was probably a good few times stronger than it needs to be. So you have options.. Replace the bulb in the lamp - its a car headlight bulb of H3 fitting, you can pick up 55w ones from halfords which would extend the use out to over an hour, which might be more useful in the field. Put the filter on something that's less bright but lighter and more useful in the field - which is what I am going to do. First up is the deben tracer max pro I have sat there. No better place for the filter now I think of it, and that lasts longer, is lighter to carry and generally more useful out in the field.

Ferretboy111 Posted January 22, 2007 Report Share Posted January 22, 2007 That was my plan, my deben max pro, the battery lasts around 1hr 1/2. Alex Quote Link to comment Share on other sites More sharing options...
pin Posted January 22, 2007 Author Report Share Posted January 22, 2007 You know deben sell an IR filter made specifically for that lamp, don't you? (Deben item no. GA2553IR @ £19.99) I picked up a second hand one off karlgixer on here, but I still want to make one myself - its taken a lot of research and thought so I have to do it, if that makes any sense Quote Link to comment Share on other sites More sharing options...
Ferretboy111 Posted January 22, 2007 Report Share Posted January 22, 2007 OOPS no i didnt know, is ures any good? Id hate to buy it to find out tis rubbish? Alex Quote Link to comment Share on other sites More sharing options...
pin Posted January 22, 2007 Author Report Share Posted January 22, 2007 Don't know its not here yet Should be tomorrow then I will get it tested Quote Link to comment Share on other sites More sharing options...
Ferretboy111 Posted January 22, 2007 Report Share Posted January 22, 2007 Ok wicked, well as soon as u have tested it, i shall then buy one, saves so much hassle. I would of thought it would work perfectly well, out to distant ranges, as the beam currently goes a fair old wack. Alex Keep me posted.

pin Posted January 22, 2007 Author Report Share Posted January 22, 2007 Depends on how IR there is coming from the lamp and how efficient the filter is. The 3million candle power thing has a beam which you can see on distant trees out to half a mile, I'd say it was about 1/3rd the brightness with the filter on under the NV - so I am hoping for a good 100yds+ from the tracer Quote Link to comment Share on other sites More sharing options...
Ferretboy111 Posted January 22, 2007 Report Share Posted January 22, 2007 Anything out to 100yrds is perfect for what i need it for, currently the LIDL's one goes around 70yrds to be seen clear. Just need a longer range and brightness/clarity. Deben rarely let me down. Alex Quote Link to comment Share on other sites More sharing options...
pin Posted January 22, 2007 Author Report Share Posted January 22, 2007 ****** it New filter stuff doesn't do it either, I need to do some more working out I am beginning to think its not the filter but the bulb, perhaps it doesn't have sufficient of the correct frequency light in it to work, so going to look into different types of bulbs.

Ferretboy111 Posted January 22, 2007 Report Share Posted January 22, 2007 The tracer max pro filter doesnt work either? how very very bizaare. And ive ordered 1 Ah well. Alex? Quote Link to comment Share on other sites More sharing options...
pin Posted January 22, 2007 Author Report Share Posted January 22, 2007 No the filter stuff I ordered doesn't work, still don't have the deben one, hopefully tomorrow. Quote Link to comment Share on other sites More sharing options...
Ferretboy111 Posted January 22, 2007 Report Share Posted January 22, 2007 Oh thank god, i rang up deben and she didnt have a clue really about it, but she says it works with all nightvision stuff, i asked bout wavelengths etc, lol certainly stopped her talking..... Well ive ordered one, so cant wait to try it out. Alex Quote Link to comment Share on other sites More sharing options...
pin Posted January 22, 2007 Author Report Share Posted January 22, 2007 Ok, so turning on my brain I thought, ok, so is it the filter or is it that the right frequency of light isn't there to start with (in the white light chucked out by the halogen). So with the bunny sat there blissfully unaware in the dark on the sofa I turn on the NV and light him up, backs of his eyes shining brightly. So then I pop a small square of the filter in front of the built in IR illuminator and nothing happened, his eyes are lit up just the same, perhaps a 1% drop in brightness almost could not perceive the difference. Barking up the wrong tree all the time, there simply isn't enough of the right wavelength IR emitted by the headlight. Or a torch, or anything I had to hand. The filter is passing the right wavelengths and its blocking the visible light as well - exactly like it says on the tin. So I need a new light source, which has about 805nm in abundance Quote Link to comment Share on other sites More sharing options...
Ferretboy111 Posted January 22, 2007 Report Share Posted January 22, 2007 Wicked, do you reckon ill need one for the tracer max pro? Alex i assume so?? Quote Link to comment Share on other sites More sharing options...
pin Posted January 22, 2007 Author Report Share Posted January 22, 2007 I need 10 minutes on some universities photon-spectroscope armed with bunny and NV goggles and then I wouldn't have to faff about Its bloody annoying trying to measure something you can't see and work out how much of it there is Its starting to do my head in now, time for a beer Quote Link to comment Share on other sites More sharing options...

the pelt man Posted January 23, 2007 Report Share Posted January 23, 2007 Hi Pin Take a look at this guy's stuff: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...s_promot_widget Only 50m range ? I will ask him about the bulbs see what he say's PELTMAN Quote Link to comment Share on other sites More sharing options...
pin Posted January 23, 2007 Author Report Share Posted January 23, 2007 Ohh, yeah ask him about the eyes thing In complete honesty I have been looking at specs of IR LED's thismorning. Quote Link to comment Share on other sites More sharing options...
the pelt man Posted January 23, 2007 Report Share Posted January 23, 2007 Ohh, yeah ask him about the eyes thing In complete honesty I have been looking at specs of IR LED's thismorning. Even though he only uses LED lamps with no reflector, Reading some of this guys info, he says that the the range is also Camara dependent. So our NV might not be able to pick up the reflection over a certain range PELTMAN Pin Just got this reply from the first e-bay seller: Infrared Lamp IR X-Ray Torch Night Vision Infra Red (280072047294) This message was sent while the listing was active. ubergoat is the seller. Hi Just tried it out with the goat and a Sony camcorder with night shot and there is most definatly reflected eye shine. I would presume therefore that combinations other than goat/sony would produce the same result. Regards ubergoat PELTMAN Quote Link to comment Share on other sites More sharing options...
pin Posted January 23, 2007 Author Report Share Posted January 23, 2007 Which is good news, but still doesn't solve the problem of low cost IR If I had £130 to spend on an IR torch I wouldn't have spent about 20 hours trying to make my own Quote Link to comment Share on other sites More sharing options...
