Lenses for sale. Lenses for your vision.

Thanks Jake for the demonstrations. Now I know why lenses cost what they
do!

Wow, I remember hearing about the alloy being used for blocking, but that’s never heard of.

I agree, the older machines take skill and sometimes take a little more time, but the optics are much better than the automated machines.

I trained (and still use!) on the Coburn 2113, and still prefer it.

Seeing that equipment transported me back to a place in time that I had almost forgotten! Thanks for re kindling some old memories, and yes we had to really know what we were doing back then. We no longer have proper optical education due to computerization.

i trained on equipment like this, a Coburn 108 CT, i miss it, the computerized ones take all the skill out of it. Two step pads give a better finish than one step pads which seem to be the norm now. These older machines are much easier to maintain too and a lot harder to break.

Yes, this equipment is well over 50 years old but it produces excellent results. Most optical eq is computerized today but in many countries mechanical tools are affordable and less expensive to operate and repair. The equipment used in this video is now in Serbia. DE at EDGE OUTREACH

Ancient equipment…

Thanks for posting this video.

Thanks for your comment Frances. Actually the first grinding process isn’t done dry. You don’t see what’s happening inside. Water is required to cool the lens during the grinding process. There are no grit or glass particles in the air. de at EDGE

Bond the grind holding block to the lens by sucking out the air between them using a vacuum? No, by pumping in between what elnoy? To clean it up, you use a what lens microsope at 06:30?
I did not hear much clear.

a pattern edger.

This is nice and the video is informative.

Today we used .only patternless edger

Thank you so much for sharing! I work in an optical shop and we send our orders to an out of state lab, so I’ve never seen how it’s actually done. This was really informative and I’m going to share it with the other opticians.

no comments? Ok, the instruments used are straight forward, but the vid is nice and informative.

Christianity is not a religion, it’s a relationship w/ yourself. It’s your brain fooling itself. It’s the equivalent of an optical illusion

No, an optical illusion. Things can appear to move/become 3d if they have a black background. A good example of this is the 3DS.

Weird problem with Dell Laptop stalling when the fan stops. I have a new (~2 month old) Dell Inspiron N4110 that I bought from Best Buy. It has an Intel Core i3 processor, 4 gigs of Memory, running Windows 7 Home Premium Service Pack 1. The computer stalls every time the fan stops running. By stall, I mean everything is unresponsive for about 3 minutes and then working again. Key strokes or mouse clicks I do during the unresponsive time will register once it working again. Usually I am word processing in Word 2010 when it happens, but not always. Typically, if I have a Firefox browser open, I’ll get a series of unresponsive script messages once the stall is over too. I hit continue and they resolve. The stall always coincides with the fan stopping, but ends while the fan is still not running. I wonder if someone can tell my why this is happening and whether there is a quick fix. My google powers have failed me. I’m under warranty of course, but would rather avoid the…

Can’t take this anymore! Needs to go to optical shop to have my eyes check!

Slow Friday in the lab !!!! But I like it

Real-time, 3-D microscopic tissue imaging could be a revolution for medical fields such as cancer diagnosis, minimally invasive surgery and ophthalmology. University of Illinois researchers have developed a technique to computationally correct for aberrations in optical tomography, bringing the future of medical imaging into focus.
