Koshin Kogaku Co., Ltd. provides wavelength tunable lasers that achieved both high wavlength purity and putput power stability at the same time, adopting our original narrow band pass filter. Its wavelength range spread over the 1-um band and other 5 wavelength ranges used for the optical communications.
Customers can choose the desired model according to the requirements. Customization of specifications is available.
Exchanging filter cassette, this product can change its transmitting wavlength and full width half maximum (FWHM). In case of the product with two slots for the filter cassettes, it can tune not only the center wavelength but also the pass band width.
Fiber-optic device type products are also in the options, which suit embedding in various optical equipment.
