-6mm FL Coated Lenses
Hi all
Anyone know of anywhere I could buy a couple of -6mm FL lenses?
I need these as a means of rapidly expanding a laser beam over a very short distance. Diameter of probably no less than 5mm as below that they become difficult to mount.
Either plano concave or bi-concave form would be suitable. Preferably reflection free coated for visible wavelengths as i'll be using them with 532nm and 632.8nm lasers.
Edmund Optics have them but I was hoping for a cheaper source if possible.
Many thanks
Jem
