I then deleted my post so not to offend anyone. JLewis posted that you had a connection to the Burntwater trading post.
#UNERTL SCOPES FOR SALE EBAY CODE#
Is there a password or code key to decipher this ?īurntwater, In response to your post about chuckles, I wrote one saying I got a chuckle when oxymorons are used. Rollingblock, actually he has a family connection to: (You need to Login or Register to view media files and links) If you haven't tried a 15x 2 inch Unertl, you are missing out on a jewel. Let me add this: I do not believe I can shoot a better target with the higher powered Lyman. (You need to Login or Register to view media files and links) I'm no expert, so correct me if I am wrong. I believe I can see more detail on the target with the lower powered Unertl than with the Lyman, and the reason is higher resolution. I think the objective on the Lyman is 1-1/2". I have a Unertl 15x 2" and a Lyman 24x STS. Magnification is a factor, but higher magnification without increasing your objective diameter gets fuzzy in the focus.
I'm no expert, but I think they hit a sweet spot with that scope. The larger objective gathers more light and allows for a sharper focus. All a product of lens quality and resolution. There's a big reason: Clarity and brightness. Unertl sold a heck of a lot of their 15x 2" scopes. Resolution with any optical device is a big deal. But in the end the buyer has eliminated the risk of all their eggs in one basket and a run of bad or marginal glass that could shut down production Of the 6-10 shops maybe one or two don’t cut it so they are out. Each of these small shops knows all too well that they must supply perfect lenses or never get another contract. Instead of letting a contract for a thousand lenses to company ‘Big’ like we do in the USA, Japan will put our contracts to like six to ten small shop lens grinders and factor in maybe 25% more than needed. You may be interested to know how the Japanese deal with quality control in the lens grinding business. They in affect get real close, real fast, real cheap. However it’s my understanding ( know an old school grinder ) that these CNC grinders work to averages and are not capable of hand polishing a lens that deviates. Of course like much of today’s old hand skills there are robotics doing lens grinding. Other than tube assembly the scope relies heavily on the lens grinder. The glass has better UV resistance and clarity.
High quality Schott glass is very very uniform so that light passes through at various wave lengths without being bent or altered due to internal defects. Just don’t look through a good one cause it will ruin you. However if the scope works for you then really that is all it needs be. You can’t build a true high quality optical device for less money cause the glass just isn’t cheap. and it sells cause almost nobody has the equipment or the eyeballs to test and confirm good quality optics. These reduce glare, improve low light transmission etc. Many of today’s scopes are selling performance based on their coatings. The glass is expensive but no good lens grinder wants to risk their reputation on less than the best glass. This German company now in the US is the finest and Unertl and Fecker used these glass lenses for repeatable performance. To build the best quality optical resolution you need very high quality optical like Schott Glass. Let me add to this by just saying all scopes and optics are built around one component and that is the glass lens.
