Hello together i think i need your help guys ;) i have one question, i have this product, Sanwa Laserpointer LP1 and i need your help pls. The LP1 is callibrate of 633nm, but i want to check a laserpointer 1MW with 532nm, is there any formula to recalculate for an virtue of 532nm. I cant find this 532nm in the manual, maybe you can help, that would be nice ... Iam not sure whats the bill ... thank you so much wishes

Hi Jim, thanks for your fast reply, how do you calculate that ? is there a special formula ? 488 nm x 2,08 500 nm x 1,93 515 nm x 1,71 550 nm x 1,39 600 nm x 1,12 532 nm ? or 1,34 ;) but how you calculate that normaly it must be between 1,39 and 1,71 thanks so much wishes

You are right... the number seems off. Looking at the data on the Graph Between 515nm and 550nm the graph is fairly linear. The spacing between wavelengths 515nm and 550nm is 35 points. The spacing between multiplication factors 1.39 and 1.71 is 0.32 points That is a ratio of about 0.0091428 per nm at that part of the graph. If you take the different from 515nm and 532nm (17 points) and multiply it by 0.0091428 you get ~0.1554. Take multiplication factor 1.39 and add 0.1544 and you get roughly 1.545 as the multiplication factor at 532nm. Since that is an Optical LPM it will not read correctly and probably high since it will also see ant IR that is not completely filtered out. BTW... you are in the WRONG section of the Forum this has to do with testing and LPM calibration. It has nothing to do with Companies. Ask one of the Mods to move it for you...

Hello Jerry, thank you so much for explaing, ok so i will add now the factor x with 1,545  but i think thats correct 1,4554 because 1.3 + 0.1554 = 1,4554 Thanks, will ask the mod to move the thread Thanks again Jerry wishes Last edited by Laserpower; 07242012 at 07:15 PM.
