ADC offers the most complete set of ultra-high-precision slits from monochromatic to white beam that includes; Micron precision, encoder option, ability to monitor the beam, best slit blade edges in the synchrotron community, and blades can go "past closed" without clashing (Overlapping/Zero beam). Our slits are being used in many synchrotrons, neutron and x-ray facilities around the world (APS, NSLS, ALS, DLS, NSRRC, BESSY, DESY, CHESS, ESRF, BSRF, CAMD, NSRL, PAL, LNLS, CLS, SSRF, ANKA, KEK, SPring-8, ASP, ELETTRA, MAX-LAB, …)
