Steve do you guys still make this?

[Jeff Trail]

Steve,
I seen the thread on lens thickness and I was going through some of my stuff in the lab and a few years back I got a "slide" rule from a SOLA rep that when you moved the scale to a certian power (plus on the front, minus on the back) looked up in another window and it gives you the CT for the plus powers and on the reverse the edge thickness on the minus powers compared to CR39 and spectralite... in 3 different blank sizes (50 mm, 60 mm, 70 mm) ...this little slide sure comes in handy and we even took it a step furthe and had a rough formula (scale) to go into other indexes attached to it.. of course it is all based on zero decentration but it sure is a fast way to check to get a pretty good idea...
So do you guys still make this slide rule? it's about 9 inches long and 3 or so inches wide and is a nice mauve color :)
Just thought some of the guys that were in the other thread might want to get one.. comes in pretty handy.

Jeff,

Here's the answer from our Tech Services department (p.s. you should try calling them sometime!) :)

The part referred to is what we call "slide chart" and is listed in the collateral guide under Spectralite.

The part number is #000 0138 87400.

Hey Jeff,

I use that one too! Its a gorgeous purplish pink color! Every so often, you work with that structural engineer type who just has to know that his Spectralite +3 lenses will be exactly 15.4% thinner than CR-39...

I posted it in the hopes (be it so slight) that SOMEONE would say..hey I want one :)
But so far only us who have one claimed it. I had hoped the ones who were in the other thread about thickness would have seen it and called SOLA, since Steve was nice enough to check on it and even give the department to call and you gave out the number :rolleyes:
I did my good deed for the week .. :)

Thanks Guys,

I ordered mine!!

I hope you're all having fun & making money!!

You can also figure out the thickness by using the edge thickness formula. 1. You need
eye size,bridge,effective diameter and pd 2.
You need to determine the power of the lens through 180 meridian 3. determine the lens
material or it's K value 4. Multiply the power by the K value and add the minimum thickness. MBS=(GCD-PD)+ED or you can use the simple ruler Steve talked about. Whew that tired me out all that writing. I m going to take a nap.

[mullo]

I'll have to check this out. What is the cost??? Mullo

[Steve Machol]

No cost unless they've changed policy since I left. Just call Sola's Tech Service department at (800) 358-8258, #3.
