Scitec Instruments supplies a range of
high quality synthetic crystals. The use of high quality
starting materials for crystal growth, whole boule
interferometry, and precise measurement of bulk losses
using transmission spectroscopy ensures that each
crystal will perform to customer specifications. Each
rod is inspected with a 532nm laser to verify it is free
of bubbles and inclusions. Advanced growing and
manufacturing technology and state-of-the-art
fabrication and coating processes result in a
consistently reliable finished product. Our product
range offers a wide variety of finished laser rods and
slabs with high optical homogeneity, consistent
performance and high processing accuracy suitable for
R&D and OEM requirements.
|
 Non-
linear Crystals |
NEW Nonlinear optical (NLO)
crystals are used in frequency conversion for
lasers. We supply a complete line of NLO
crystals including BBO, KTP, KNbO3,
KDP & DKDP and LiNbO3 crystals. |
|
Laser
Crystals |
NEW Laser crystals are used to
generate laser radiations. Laser crystals
supplied by Scitec Instruments include Nd:YVO4,
Nd:YAG, Nd:YLF, Er:YAG, Cr4+:YAG,
Yb:YAG, Ti:Sapphire and Cr:Mg2SiO4,
etc. We also provide complete kits of crystals
and optics for diode pumped solid state lasers. |
|
EO
& AO Crystals |
NEW Electro Optic (EO)
Crystals: When an electric field is applied to
an EO crystal, the refractive index of the
crystal will change linearly with the electric
field. Acousto-Optic (AO) Crystals: When a
piezoelectric transducer is bonded to an AO
crystal, it will generate an acoustic travelling
wave or standing wave in the medium. |
|
Optical
Crystals |
NEW Optical crystals and
glass, such as quartz, YVO4, Calcite,
a-BBO, LiNbO3, undoped YAG, Sapphire,
CaF2, MgF2, BK7, etc are
widely used in IR and UV optics. We supply high
transparency and low loss optical windows,
prisms, lenses, achromatic lenses and parallel
planes in these optical materials. |
