Photex Laser provides customized660nm 120mW red Powell lens line laser module
sfeaturing an adjustable line width as fine as 0.1mm at close working distances,
uniform line intensity and reduced bright spots at both ends for precision positioning,
alignment and industrial marking applications.
The 660nm 120mW Red Powell Lens Line Laser Module is designed for applications
requiring a thin, uniform and highly stable red laser line.
Featuring a Powell prism optical system and semiconductor laser diode,
the module produces a straight, evenly distributed line with minimized endpoint hotspots.
Its externally adjustable focusing structure allows users to optimize
line width according to installation height and working distance.
The standard Ø16×90mm housing supports industrial integration,
while alternative dimensions and optical configurations are available for OEM applications.

Line widths are reference values under the stated working-distance conditions.
Actual results depend on focus adjustment, installation and optical configuration.
Unlike conventional cylindrical lens systems, a Powell prism redistributes
laser intensity to produce a more uniform line profile.
The optical design helps minimize excessive brightness at the center and reduces bright spots at both ends of the projected line.
This makes the module suitable for precision alignment and optical positioning systems requiring consistent line visibility.
The adjustable optical head allows operators to modify laser line thickness without intentionally shifting the line position.
Once the desired line width is achieved, the locking mechanism helps maintain the selected focus setting during equipment operation.
