Re: Optical bandpass for laser-app: source?

There are bandfilters for example at edmund scientific.
If they are't suppressing sufficiently, you could
consider a Faby Perot, built from 2 mirrors.

Hi Rene,
no, it is only one of them. I just want to seperate one laser line in
the image - but I can choose the laser.

Dear colleagues,

we are looking for an narrow optical bandpass filter for a laser
scanner application. The lasers are 635 and 650 nm. The only source I
have found is Semrock Inc. (Laser-line product line) but they are
around 300 dollars (!). Is there a cheaper source?

And you intend to separate theses two lines
with the filter ? Or you want only them to
pass ? Please supply some specifications.
