Re: GB FEELER--150mW(peak 220) Pro Green laser
We added the ir filter unless the customer asks to remove it.
The specs of the ir filter we use for the time being are as follows:
T>96% & 532nm
T<0.5% & 800-1100nm
10mm Diameter
Thickness: 1.0mm
These ir filters are not that cheap as we thought, but there are many really cheap ones here in China. Some are also underspeced. For example, the transmission rate may be 92% or lower when the vendor claims to be 95% or higher. To get all what you pay for is good if possible.
Just as Pontiacg5 said, people are not 100% honest. You may be upset by dealing with rayfoss but rayfoss is not that typical of Chinese people. I'm not going to talk about this any more. Anyway, We learn the lessons well and no longer easily misled thanks to them.
