SDA Manufacturing Announcements

Cross-Hair lens with improved sharpness

After months of searching, we now have a lens that offers improved sharpness over the working range.

Double Polarizer for Cross-Hair &
Concentric Circle Lenses

A “Double Polarizer” is included with all Cross-Hair and Concentric Circle units. This polarizer provides improved adjustability in line visibility that was not previously possible.

Brighter laser and smaller dot size!

The polarizing attachment is now included with the purchase of all of our units.

Design improvements in the laser module and laser aperture have allowed us to achieve an even smaller dot size, brighter dot, and longer operating distance when used in conjunction with the polarizer.

We continually strive to build a better product and achieve greater accuracy. We also rely on customer feedback to let us know when things work and when they don’t.

Brighter laser and smaller dot size!

First, all units (except CNC models) are now available with either battery power or our new A/C powered variant.

Second, SDA has developed a bridge mount A/C unit specifically made for permanent installation on waterjet and wood CNC machines (gantry-type). Keep this unit in place and there is no need to install the LC/EF on the nozzle or mill collet each time.

Third, two special lenses are available on all units; a crosshair and a circle lense. These lenses are available in either the battery or AC powered units.

Each lens is permanently installed in a dedicated LC/EF and the lenses are not available alone.

The crosshair lens is useful for aligning the workpiece on the table. The circle lens is useful for re-entering a hole already drilled.

Please take a few minutes to peruse our new accessories and we hope all your Laser Center/Edge Finder ® products serve you well.
