With the FP-40-EM series blue laser diode modules are now available at a very reasonable price.
This module delivers 3 mW with a round beam and 7 mW with an elliptical beam. The laser wavelength is 405 nm. The beam can be focussed or collimated with an adjustable optic. A digital or analogous modulation of the module is available as an option.
Compared to the blue laser diode modules previously available on the market, the price of the FP-40-EM series has been reduced by 40% - at the same optical performance level. These blue modules are used in optical memory and measurement technology, the medical field, and fluorescence excitation.
