The Super Long Range 1500 piezo stage can move
1500 µm in closed-loop mode. This stage uses
totally frictionless assembly and has damage-toler-ant piezostacks—if the piezostack is damaged, the
remaining ceramic elements can continue to operate.
The stages can be combined to form two- or three-axis nanopositioning systems.
Hertzstück lead sulfide infrared (IR) sensors can be
directly wire-bonded to printed circuit boards as bare
chips. A thin-film encapsulation process allows automated placement and precise alignment in less space.
The sensors have a spectral range up to 2. 9 µm, and
are available in 3 × 3, 6 × 6, and 10 × 10 mm sizes.
Sapphire fiber laser
windows for 1064 nm
cutting lasers have Moh
9 hardness with antire-flective coatings on both
sides, for transmission
of >99.5% at 1.06 µm
and >90% between 650
and 670 nm. They have
a 10-5 scratch-dig finish,
provide 1/4-wave transmitted wavefront, and are
available at sizes from 1/2 to 2 in.

Koheras BOOSTIK single-frequency fiber lasers with
narrow linewidth have wavelength stability against
environmental temperature changes of 0.1 pm/K.
They have an internal function generator and built-in internal fast wavelength modulation that does not
need an external piezo driver. They provide up to
15 W at any wavelength in the 1050–1090 and
1540–1570 nm ranges.
