The
skilful engineers and technicians at
Dream Lasers are developing specialized fabrication
techniques for optical components to meet the requirement
of the highest international standards. Dream
Lasers possesses two large production lines for
fabricating Plan and Sphere custom-made optical components.
Especially, it has reached a high capability of producing
Penta Prism and Waveplate over 100,000 pieces each per month.
With occupation of many experienced engineers, advanced machines,
using the latest design techniques, our coating department
is able to meet your wide range of demand.
In
addition to standard optical components described in the above
pages of this catalog, Dream Lasers
designs and provides a wide range of custom optics. Based
on our two large production lines in fabricating Plan and
Sphere optical components and our skilful engineers and technicians,
Dream Lasers is not only
capable of serving high volume order but also in a position
to provide as few as single piece custom-made part. Custom-made
components are normally quite cost intensive. However, one
will find that his budget will no longer be so tight if he
chooses Dream Lasers. Please
keep in mind that Dream Lasers
is really unusual. Our engineers are always ready to take
the chance to discuss with you for your custom-made parts.

Dream
Lasers processes thousands of radius test
pieces for fabricating lenses in stock. Our customers
may benefit a lot from our large tools inventories because
they do not need to pay additional tooling charge, which
may be quite high among overall cost percentage for
small amount orders. In additional to that, our customers
can have larger flexibility in designing their systems
for there are quantity radius can be selected. Large
tools stock further means quicker delivery due to saving
time in fabricating tools.

Dream
Lasers has developed a particular technology
in fabricating high precision Penta Prism (up to 5"
deviation) and Beamsplitter Penta Prism. A large production
line for Penta Prism has been established with capability
of producing more than 100,000 pieces per month.
Roof-Angle
Prisms, Dove Lens, Fresnel prisms, Polygonal Prisms,
Porro Prisms, Pechen Prisms, Amici-Dove Prisms, Coupling
Prisms, Hollow Retroreflectors,.....are also available
in Dream Lasers.
Dream Lasers is especially
good at fabricating special shape prisms.

| Waveplates |
With
the experience on orientating and fabricating high quality
nonlinear optical crystals, Dream
Lasers assures to control the orientation of
the crystalline axis precisely maintained from first cut
through final assembly. Dream
Lasers has set up a computerized system to
produce more than 20,000 pieces of multipule order and
zero order waveplates per month. Dream
Lasers has organized a strong R&D team
on the waveplate project that it is possible to provide
any technical supports as needed.

Dream
Lasers' quality control and assurance department
sets a series of complete standards for the optical
components. Every product is strictly inspected to meet
our standards or specifications required by customers
before it leaves Dream Lasers.
Inspection reports and pictures are available upon request.
Some of the main inspection instruments are:
0.5
arc second goniometer
Laser plano interferometer
Twyman Green interferometer
Pekin-Elmer lambda 19 UV/VIS/IR spectrophotometer
Zygo GPI-XP interferometer
Waveplate Retardation Inspector
pico-second Nd:YAG laser
40mW He-Ne laser
CW Diode pumped Green laser
