Features
(1) Maximum optical output : 5mW
(2) Wavelength: 635nm
(3) Compact ø5.6mm package
(4) Stable transverse mode
(5) High temperature operation at 60˚C
(7) Realizes high temperature operation by introducing a tensile strain
into the multi-quantum well active layer.
(8) Stable optical characteristics by developing an index guide
structure of MBE method 2 times growth
(9) Pair use with Sharp's OPIC* light detector
IS1630
is
recommended.
