Lenses
We possesses thousands of radius test pieces for fabricating lenses in stock. Our customers will benefit from our large tools inventories because they do not need to pay additional tooling charge, In addition to that, our customers can have greater flexibility in designing their systems since there is a wide valiety of radius that can be selected. Large tool stock further means quicker delivery due to saving time in the fabrication of tools.
1. Aspherical Lens
2. Spherical Lens
3. Cylindrical Lens
4. Achromatic Lens
Materials: please refer to "Optical Material"
Diameter: f1 - f100 mm
Focal Length: 3 - 1,000 mm
Prisms
We has developed the ability to fabricate with high precision Penta Prism (up to 1" at 90° deviation) and Beamsplitter Penta Prisms. A large production line for Penta Prism has been established with capability of producing more than 100,000 pieces per month.
Polarizing Optics
We specializes in developing, growing and fabricating birefringent crystals, such as YVO4, a-BBO, LiNbO3, MgF2 and Quartz crystals. Many polarizing optical components have been developed based on our birefringent crystals, which include Glan Laser Polarizing Prisms, Rochon Polarizing Prisms, Polarizing Beamsplitters, new Phase Retardation Plates, Achromatic Fresnel Rhomb Retarders, Birefringent Filters and Birefringent Wedges, etc.
Waveplates
With the experience on orientating and fabricating high quality nonlinear optical crystals, We assures that the orientation of the crystalline axis precisely maintained from first cut through final assembly. We has set up a computerized system to produce more than 20,000 pieces of lower order and zero order waveplates per month. We has a strong R&D team on the waveplate project to provide any technical support as needed.
Inspection Instruments
Our 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 the specifications required by customers before it leaves our company. 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 900 UV/VIS/IR spectrophotometer
Zygo GPI-XP interferometer(2)
Phase retardation inspector
Pico-second Nd:YAG laser
40mW He-Ne laser
CW diode pumped Green laser
Spectroscopic Ellipsometers
Spherometer
Automatic Lens tester
Japanese Laser Interferometer
MTF testing machine
Focal Adjustment machine
Spectrum machine and optical Collimator
