Import Aspherical Condenser Lens — Buy in wholesale FOB from Supplier in China

West Coast Tech Ltd. offers molded aspherical condenser lenses engineered for illumination and projection systems requiring large apertures and short focal lengths. These lenses are molded on the aspheric surface and ground and polished on the opposite face, a manufacturing approach that reduces spherical aberration compared to conventional spherical condensers. Diameter spans 8 mm to 350 mm with a diameter tolerance of +0/-0.2 mm, focal length tolerance of +/-1%, and center thickness tolerance of +/-0.3 mm. Surface quality is rated at 60-40 scratch-dig with surface accuracy of PV 30-40 microns, and centration is held to 3 arc minutes. The supplier specifies pyrex glass or fused silica as standard material options, with anti-reflection coating available on request.

The aspheric profile on these condenser lenses eliminates the need for multi-element spherical assemblies in many emitter-detector and Köhler illumination setups. Pyrex glass offers thermal stability and low coefficient of expansion, making it suitable for high-intensity illumination where thermal loading occurs; fused silica extends this into UV transmission regimes. The ground and polished second surface provides a precise reference plane for mounting and alignment. Typical applications include microscopy illumination, machine vision lighting, theatrical projection, and LED/laser collimation where uniform illumination of a target plane is critical. The 60-40 surface quality suits most commercial and industrial lighting needs rather than laser-grade applications.

Buyers for this component span scientific instrument manufacturers, theatrical lighting suppliers, semiconductor inspection equipment makers, and medical device integrators. The broad diameter range supports both compact portable systems and large-format projection engines. West Coast Tech Ltd. lists no minimum order quantity or standard lead time in its profile, and its response rate is currently zero, so direct enquiry is essential to confirm current capacity, coating options, and volume pricing. Buyers should specify wavelength range for AR coating, thermal operating limits, and whether the application requires transmitted wavefront data beyond the stated surface accuracy.

West Coast Tech Ltd. is located at No. 133, Tianquan Road, Fuzhou, Fujian Province, China, postal code 350003. The supplier carries an 'imported' tier designation and holds a 'harbor' trust tier. Its response rate is listed at 0.00% with zero average response hours recorded, indicating no recent buyer engagement through the platform. The company profile contains no stated year of establishment, employee count, revenue figures, or named clients.

The listing focuses on optical components, specifically molded aspherical condenser lenses for illumination applications. No certifications, factory audit details, or production capacity figures are provided. Buyers should verify current production status, quality management system registration, and sample availability directly with the supplier given the lack of response history.
