We can supply lenses to your specification:
Doublet and triplet Lens
Materials: A full range of optical materials
Diameter: 1 – 100 mm
Focal Length: 3 – 1,000 mm
We can fabricate high-precision Penta Prisms (up to 1″ at 90° deviation) and Beamsplitter Penta Prisms, Schmidt Prisms, Penta Roof-Angle Prisms, Polygonal Prisms, Porro Prisms, Pechen Prisms, Amici-Dove Prisms, Coupling Prisms, Hollow Retroreflectors.
We specialise in developing, growing and fabricating birefringent crystals, such as YVO4, a-BBO, LiNbO3, MgF2 and Quartz crystals. Many Polarising optical components have been developed based on our birefringent crystals, which include Glan Laser Polarising Prisms, Rochon Polarising Prisms, Polarising Beamsplitters, new Phase Retardation Plates, Achromatic Fresnel Rhomb Retarders, Birefringent Filters and Birefringent Wedges, etc.
With our experience orientating and fabricating high-quality nonlinear optical crystals, we ensure that the orientation of the crystalline axis is precisely maintained from first cut through to final assembly. We have a computerised system to produce large quantities of low-order and zero-order waveplates per month.
