HOW WOULD YOU DESIGN A COMPUTER-CONTROLLED SINGLE-CRYSTAL DIFFRACTOMETER?
Rigid construction . . . flexible operation. Maximum accuracy . . . minimum cost. Reliable hardware ... realistic software. Doesn't this just about sum it up? Now take a look at. ..
T h e new Philips P W 1 1 0 0 . . . designed a n d p r o g r a m m e d by crystallographers themselves! Any way you look at it, the Philips PW 1100 is really W e think it's the way you would design a computerthe crystallographers' diffractometer. From its patented controlled single-crystal diffractometer. two-point chi-circle suspension (vital when using Order Brochure PW 1100 and see for yourself. crystal-monochromatised radiation) to its unique "manmachine dialogue" concept of controller operation, this instrument is tailored to the special needs and N.V.

Now the software. Standard routines are pre-programmedbycrystallographers iSpec'ia programmes...for automatic orientation, lattice parameter refinement, checking procedures, etc...are available too. Most interesting of all is the provision for a dialogue between you and the computer when determining unit cell, orientation and lattice parameters.
