Light emitting device

A light emitting device comprising:

• a base defining a recess;
• a lid portion covering the recess so that a hermetically scaled space is defined by the lid portion and the base, the lid portion having a bottom surface fixed to the base and a top surface opposite to the bottom surface;
• a first semiconductor laser element provided in the hermetically sealed space, the first semiconductor laser element being configured and arranged to irradiate a first light having a first peak wavelength in a visible range;
• a second semiconductor laser element provided in the hermetically sealed space, the second semiconductor laser element being configured and arranged to irradiate a second light having a second peak wavelength in the visible range, the second peak wavelength being different from the first peak wavelength;
• and
• a collimate lens fixed on the top surface of the lid portion with an adhesive, the collimate lens having a plurality of lens portions including a first lens portion through which the first light passes, and a second lens portion through which the second light passes.
