    Default What's difference 635nm, 637nm, 638nm, 640nm?

    I feel a little confuse for the different, I think 637nm, 638nm and 640nm are the same, 635nm is different with the three wavelength, now some companies also say 635nm as 637nm. I don't know what shall we do.

    Do you represent Able Laser or have any connections to the company?

    I ask because if you do I'm surprised you are asking such a question.

    You are using Bonetti's defense against me, ah?

    I thought it fitting, considering the rocky terrain.

    I'm not surprised by the confusion, I've seen the G series Mitsus referred to as 635, 637 & 638. DTRs shop refers to the G71 as 635 & 638, on the same page of his web store.

I need to use it for my annual Brony-party.. What do you all thinkk? Oh, pleeeeaze help me, whatever shall I doooo?' Barf..

    I doubt this is spam, as there is no product link in the original post. I genuinely think it's just confusion based on the same diodes being referred to as different wavelengths.

    Yes, I work at ABLE Laser company. But we saw some company's 637nm spec is similar with our 635nm, some guys said that the wavelengh is as the same as +/-5nm, so I fell confusion. Maybe it is imporstant to see the beam quality spec, beam diameter and divergence to see the different.

    this 635nm should be old model, the beam diameter is as the same as 650nm. how do you think 637nm and 638nm? I think that 637nm and 638nm are as the same as 640nm.
