Hanzhong Brisun Optics Co., Ltd. Is the high High precision optical element manufacturer provides customized production of Various optical lenses, including spherical lens, cylindrical lens, optical window, mirror, prism, filter, metal base mirror and other high-precision optical elements. The base materials include various optical glass, fused quartz, calcium fluoride (CaF2), zinc selenide (ZnSe), germanium (GE), silicon (SI), sapphire, metal and other materials. And provide antireflective film, high reflection film, spectroscopic film, metal film and other optical coatings. The light parallel to the central axis of the paraboloid is reflected by the paraboloid and converges at the focus. Off axis paraboloid reflector, the reflector is a part of the paraboloid, and the focus is outside the optical axis. Borisun optics launched the off-axis paraboloid mirror standard with a diameter of 25.4mm and a diameter of 50.8mm, which is plated with gold film, silver film and aluminum film and an off-axis angle of 90 . According to different coatings, it has good optical properties in the visible band, near-infrared band and infrared band. The surface roughness of these off-axis paraboloid mirrors are 50 and 100 respectively, which can effectively reduce the scattering of light in application. It is widely used in reflective optical systems Laser focusing system, terahertz and other products or related fields, we can also customize products that meet your needs. Technical parameters: Material: optical glass, H-K9L (N-BK7), quartz Radius of curvature: ± 1mm - ± 50000mm ± 1% Outer circle: 3mm-500mm ± 0.1mm Center thickness tolerance: ± 0.05mm (we can process to ± 0.01mm with high precision) Center deviation: 3²(we can process to 30 ³with high precision) Surface accuracy: / 8 (high precision, we can process to 1 / 10) Surface quality: 60/40 (we can process to 10-5 with high precision) Effective caliber: 90% Coating: according to the customer requirements In addition, we have thousands of kinds of stock, such as quartz plano convex lens, quartz plano concave lens, quartz biconvex lens, quartz biconvex lens, cylindrical lens, prism, filters, windows, beamsplitter and so on. The price is preferential and the quality is excellent, which can meet your demand for a small order.
