WTB: Lenses for Laser 301

[Marco Polo]

I need to replace the lenses in some of my 301's. The threaded lens holder is slightly larger in diameter than the 9Mx0.5mm. I think it might be 10mm. The 0.5mm thread width is definitely correct.

I would prefer glass lenses. Single-element or three-element are OK. AR coated for 405nm to 455nm is also OK (although they will be used in 532nm lasers).

If anyone knows a good source for lenses, either in a holder or just the bare lens itself (I think it's a 5mm lens) please let me know.

The 9Mx0.5mm ones are too small.

Edit: Below is the specific part I would like to replace:

Bumping this since I added a photo of the specific part that I would like to replace.

Please contact me if you know where to get this part, or if you can supply it.

Thank you!
