Karel Bata Posted February 3, 2018 Share Posted February 3, 2018 Hi, I've got a couple of Chauvet LED pinspot 2s that I'm modifying for a specific install. Nice lights BTW! http://www.blue-room.org.uk/public/style_emoticons/default/smile.gif https://www.amazon.co.uk/gp/product/B003N7BCFE/ref=oh_aui_detailpage_o07_s00 They come with 50mm diameter lenses giving 6 and 9 degree beams. (I haven't figured out the focal lengths yet.) I'd like some other beam angle options, so I'm looking for sources of decent quality lenses. Anyone here know a good source? Many thanks! http://www.blue-room.org.uk/public/style_emoticons/default/wink.gif Link to comment Share on other sites More sharing options...
Brian Posted February 3, 2018 Share Posted February 3, 2018 British Optical would be a good place to start. Link to comment Share on other sites More sharing options...
Karel Bata Posted February 5, 2018 Author Share Posted February 5, 2018 Thanks Brian. http://www.blue-room.org.uk/public/style_emoticons/default/wink.gif They haven't anything at the small size I'm loking for, but I'll write to them - they're likely to know who else might help. Cheers. Link to comment Share on other sites More sharing options...
sandall Posted February 5, 2018 Share Posted February 5, 2018 From memory the condenser lens in a CCT Minuette condenser profile was (is?) about 30mm diam, & almost certainly came from them, so they should be able to handle small sizes, though a one-off might be a bit expensive.

Karel Bata Posted February 5, 2018 Author Share Posted February 5, 2018 Gotta be somewhere in China (I know) that knocks these out for something or another. Link to comment Share on other sites More sharing options...
p.k.roberts Posted February 5, 2018 Share Posted February 5, 2018 A quick fleabay search threw this up (and I'm sure there are others) - no idea about the quality, but cheap enough to find out. https://www.ebay.co.uk/itm/Double-Convex-or-Concave-Magnifying-Glass-50mm-Diameter-lenses-Free-UK-Postage/322316965297?hash=item4b0b9695b1:I:322316965297 Link to comment Share on other sites More sharing options...
Karel Bata Posted February 5, 2018 Author Share Posted February 5, 2018 Thanks, but I've got a pair of 500mm of those already ( which I'd bought for something else). Tried them. Decent quality, but far too wide. I doubt the 1000mm (the max they have on eBay) will be narrow enough. I'll get a laser out and a couple retort stands and work out what focal length I need. Might be worth asking the seller on eBay. Link to comment Share on other sites More sharing options...
Karel Bata Posted February 6, 2018 Author Share Posted February 6, 2018 OK. So I've been doing the measurements and a 6º lens is 125mm, while a 9º is 100mm. So I think I'm looking at a 150mm lens to go to a more narrow angle. Meanwhile I seem to have got the decimal point in the wrong place (!) and your link p.k. does actually offer 150mm.! Thanks. http://www.blue-room.org.uk/public/style_emoticons/default/wink.gif Link to comment Share on other sites More sharing options...
Brian Posted February 6, 2018 Share Posted February 6, 2018 Would be interesting to see how long a FL you can go on those unit. Link to comment Share on other sites More sharing options...
alistermorton Posted February 6, 2018 Share Posted February 6, 2018 At the price it's got to be worth the experiment - try 200, 500, 1000? Link to comment Share on other sites More sharing options...
Karel Bata Posted February 7, 2018 Author Share Posted February 7, 2018 I've ordered a couple and will report back with photos. http://www.blue-room.org.uk/public/style_emoticons/default/wink.gif Link to comment Share on other sites More sharing options...
