GH20707S2A/GH20707S2B
GH20707S2A/GH20707S2B
(Under development)
s
Features
(1) Dual-wavelength type
With 2-laser chips for CD-ROM and for DVD-ROM
(2) Employing a self-oscillating laser chip enables a compact
and low cost pick-up.
It eliminates the need for radio frequency modulation
circuit and related resistors/shields.
(3) Wavelength : TYP. 788nm/654nm
(4) Maximum optical power output : 7mW/7mW (CW)
(5) Operating temperature : MAX. 70˚C
(6)
φ5.6mm
