Open Beam Butterfly (Single-Mode)

The butterfly package offers more pin configurations than the TO-Can and tends to be easier for board mounting applications. TE cooling is external, and internal TE cooling is available upon request.

The single-mode packaged product line comes standard with a circularized output beam, internal photodiode, thermistor and ESD protection. Lasing wavelength can be accurately specified and repeatedly manufactured to within +/-0.1 nm upon request.
