X-Ray Slits SLT-100-P

 

X-Ray Slits SLT-100-P

 

SLT-100-P is from a new family of X-Ray slits ADC has introduced. The SLT-100-P is ADC’s latest design that incorporates many improvements/feedback we have received from hundreds of our customers that have been using the SLT-100 X-Ray Slits (Blue Slits).

 

These improvements includes:

-Better O-ring design resulting in a better and long-term consistent vacuum (eliminating any

  biding)

-Much better quality bearing and simpler assembly

-Bigger micro stepper motor resulting in smoother operation

-Bigger and better quality drive screw mechanism for higher precision and better accuracy

 

These high-precision slits systems consist of four blades that are housed in an aluminum body. All of these slits use standard micro stepped stepper motors that can be controlled with a wide array of controllers/drivers available on the market. The design incorporates mechanical limit switches.
