https://thegr5store.com/wp/Every laser comes with a calibration card telling you the wavelength (every laser is a little different - usually 650 to 660nm). Every laser runs on normal USB power (5v) which comes from phone chargers, USB cigarette adapters, USB batteries, computers, laptops, etc. Comes with 1 meter long power cord. You must supply your own USB power source.

This laser has 2 advantages over the cheaper laser I sell: larger beam and glass lens.

The glass lens means it is easy to clean without scratching. The other laser I sell has a plastic lens secured with a spring and the spring scratches the lens more and more every time you take it apart. This laser doesn't have any spring touching the lens.

I won't test your specific lens but I have tested a few of these and they are excellent. They will give you better than 1/50 wave accuracy when using for a Bath Interferometer.

Mount for lens is included. Lens will arrive mounted.
