I have often wondered about this. Is there an actual difference in lens quality in say, the lens used on pvs14 vs Anvis 6 vs Anvis 9 and are the lens interchangeable between all three housings ( pvs14, anvis 6, Anvis 9 ). I really appreciate any and all help on these questions. What would you guys consider the best lens to use on a dual unit build that are easy to get also what dual housing do you like. I can use either mx 11769uv or 10160 F9800k tubes I have a matched set of both. I lucked out about a year and got Thales aluminum objective lens for 125.00 have not used it yet and have discovered they apparently are pretty rare so I can forget about getting another one of those. It looks really nice though. It has a greeness tint to the lens. Where as my others do not. What is the tint for. I have no problem building these. I have read a lot of posts here and built several great units. Dino has been a great help in reading his posts and others here. These are just some questions I haves always meant to ask and now that I'm getting ready to build my first dual unit I want to do it right. So what better place to get started in the right direction than here
Thanks Mack |
| There have been some pretty in-depth discussions about the different lenses in various threads. I'm not in the mood to search right now but I remember one thread that specifically discussed the differences in the PVS-14 and ANVIS 6/9 lenses to include the differences in the coating (specifically the color of the coating) and how that affected use in cockpits with glare off of lights and instruments. |

PVS-14 lenses are different to ANVIS lenses, and both types come in several different models, which have significant differences in quality - from very poor to excellent. Lens speed changes, as does chromatic aberration and transmission. Most modern lenses ( except some cheap aftermarket ones ) are excellent. Coatings on ANVIS include minus-blue - will take around 20% of your light away. These are usually rather shiny. A slight green tinge is usually that the lens is optimized for certain wavelengths and those coatings help most light to go through, rather than being reflected. It's usually just a sign of a slightly better quality lens. The absence of a slight tinge when looked at in the light is often a sign of a poorer quality lens - much as it is with binoculars. Dino knows more - and hopefully will add to this - Regards David |
| Thanks David for your help I really thank you for taking your time with me. I will not forget your help. As for the other I read the entire postings here before asking and did not expect you to search for me. Thank you for your response for letting me know some where in the years of archives I could have found my answer and that you were not in the mood to answer my question. I thank you also for your help |

I thank you also for your help I have more info on Anvis coatings I won't post. I am sure the Chinese already have this information but I error on the side of caution. PM me for more detail.
