Model Name

(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.

*OPIC : OPIC (Optical IC) is a trademark of the SHARP Corporation.

An OPIC consists of a light-detectinf ele,ent and signal-

processing circuit integrated onto a single chip.
