Import Aspherical Lens — Buy in Bulk from Supplier in China

Tian Cheng Optics Co., Ltd. manufactures glass aspherical lenses, also known as condenser lenses, for stage lighting and optical lighting systems. The supplier produces these using hot riquetting technology sourced from Japan, with volume production capability across multiple lens variants. Diameter range spans 10 mm to 300 mm, with diameter tolerance of +0.00/-0.5 mm and center thickness tolerance of +/-0.5%. Surface form error is held within 0.00 micron on finished components. The product line includes standard BK7 glass, 20 glass, and Pyrex variants, with part numbers such as TCA0208.5, TCA02, TCA03, TCA04, TCA05, TCA06, TCA020, and TCA08, TCA09 in the catalogue.

The lenses are fabricated from three material grades: BK7 optical glass, 20 glass (a Chinese optical glass designation), and Pyrex borosilicate glass. BK7 offers excellent transmission in the visible and near-infrared spectrum with low dispersion, making it suitable for general illumination optics. Pyrex provides superior thermal shock resistance for high-intensity lighting applications where rapid temperature changes occur. The hot pressing process allows complex aspheric profiles to be formed in volume without the lengthy cycle times of traditional polishing. Surface finish is specified as l/2 for the processing surface, with edge chips limited to a 2 classification. Each material grade serves distinct thermal and spectral requirements in professional lighting systems.

These condenser lenses integrate into stage lighting fixtures, cinema projectors, medical illumination devices, and semiconductor inspection equipment. Buyers include theatrical lighting manufacturers, optical instrument makers, and medical device companies requiring precise light collimation. The 10 mm to 300 mm diameter range covers everything from compact endoscope lighting to large-format theatrical spots. When sourcing, confirm the effective focal length, centre thickness, and edge thickness for your specific part number, as these vary across the standard catalogue. The supplier's location in Changchun, Jilin Province, places it within China's established optical manufacturing corridor, though import logistics and lead times should be confirmed directly.

Tian Cheng Optics Co., Ltd. is located at No. 1188 Ruipeng Street, Chao Yang Zone, Changchun 130021, Jilin Province, China. The supplier operates from Changchun, a city recognised as a centre for China's optical industry with established supply chains for optical glass and precision manufacturing equipment. The company holds a harbor trust tier classification. Its response rate is recorded at 0.00% with an average response time of 0 hours, indicating no response data is currently available through this channel. The supplier profile does not state year of establishment, factory size, employee count, or annual revenue.

The listing presents Tian Cheng Optics as a volume producer with Japanese-derived hot pressing technology, though no specific production capacity figures, certification holdings, or named client references are provided. The company offers standard catalogue part numbers across multiple material grades, suggesting a product-line approach rather than fully custom fabrication. Buyers should verify whether the supplier provides coating services, custom aspheric designs beyond the listed part numbers, or metrology reports with interferometric data. The absence of stated international standards compliance (ISO, RoHS, REACH) means these must be confirmed directly for regulated markets.
