description

The CLE333 contains a N side up,

AlGaAs, 850nm, point source die.

A special lens provides a sharply

focused beam pattern capable of

projecting a spot, 3” (76mm) in

diameter on a surface 10 feet (3.05m)

away. Designed primarily for the

encoder industry, the CLE333 has wide

application anywhere a very narrow

beam pattern is required.

mechanical axis of the device and spaced 2.54" (6.45cm) from the lens side of the tab. This is geometrically

equivalent to a 10° cone.
