Hi,
lasersam and I have a newly refurbished Burleigh WA 10L wavemeter for sale. This will read the center emission wavelength of any laser in the visible range and slightly beyond up to 200 GHz linewidth with 0.01 nm resolution. Most interferometer wavemeters will only handle around 2-20 GHz linewidth but this is a special lower resolution high bandwidth model made for diode lasers, Ti: sapphire, dye etc. The reference laser is strong, the optics are pristine, new belt, new paint. A manual is included...like new and ready to go. Phil Bergeron, 142laser (813) 974-2378
