LASOS HeNe module: LGK 7654-15 specs?

The closest on the LASOS Web site is the 7654-13, red (633 nm) 10 mW,

6.5 mA, 2.9-3.1 kV.

The -15 is probably the same tube sorted for slightly higher power. Confirm by checking dimensions.

Thanks Sam. Dimension-wise it is identical to the -8 type.

Besides the dimensions, I cannot see any other physical or performance differences between the -8 and -13. Even the weight is shown to be the same.

The type numbers on the labels (according to the datasheets) are different:

-8 has 577009-1153-000

-13 has 577009-1161-000 and mine, the -15, has 577009-1169-000

So maybe the -15 is the -8 package with a binned tube. In any case a 6.5 mA supply rather than a 7 mA should work without overload.

I have emailed LASOS but I won't hold my breath.

If it's really critical, I can ask a contact at LASOS but I think what you have is close enough for government work. ;-)

I was once told: If you can accept that a moving electron produces a magnetic field, you become an engineer. If not, you become a physicist. I am the former with the inquisitiveness of the latter.

So - besides me stewing it is not something the government would consider critical.

If you can relate to any of this Sam then I would highly appreciate if we find out what to expect from this unit. In the meanwhile I will measure optical power output at 6.5 mA.

Alex

I received a reply from LASOS.

Apparently this is an OEM version for a Leica microscope.

The datasheet can be found here, for a little while:

Kudos to LASOS!

Cheers Alex

Well, whoever told you that wasn't a physicist, I suppose. ;)

Cheers
