SummaryCrystrong Photonics Technology Co., Ltd. is a China-based limited company established in 2012, with 77 employees and operations in Shandong. It specializes in laser crystals, optical components, electro-optic devices, modulators, and related photonics products. The supplier reports more than 10 years of industry experience, 14 years of combined R&D engineer experience, custom optical component and crystal design and production capabilities, and production lines for crystal growth, optical components, and EB+IAD and IBS coating processes. It holds ISO 9001:2015 and ISO 14001:2015 certificates and has exported goods since 2003, with exports representing 31%–40% of total sales. Custom production and short lead times are explicitly claimed, but several operational, R&D documentation, quality-control, after-sales, and customer-reference fields are marked unknown. The available SGS audit record expired on 2025-09-01, so current audit validity cannot be confirmed.

Supplier typeThe supplier is identified as a combined business entity and limited company operating in manufacturing and processing machinery, electrical and electronics, instruments and meters, and related industrial sectors. Its stated products include laser crystals, optical components, modulators, Pockels cells, lasers, and optical fibers.

CertificationsThe supplier holds ISO 9001:2015 and ISO 14001:2015 certificates. An SGS audit is also recorded, but the report expired on 2025-09-01, so the current validity of that audit cannot be established from the provided information.

R&D capabilityThe supplier reports expertise in designing and producing custom optical components and crystals, mastery of growth technology for multiple special crystals, advanced optical-component and coating production lines, and 14 years of combined R&D engineer experience. However, R&D documentation availability, SDK capability, ODM capability, private mold design, and 3D design services are marked unknown.

Production capacityProduction capability is supported by the stated manufacturing activity, a 2,352.43 m² manufacturing plant, specialized crystal-growth and optical-component production lines, and EB+IAD and IBS coating processes. The supplier also claims short lead times, including for custom production, although outsourcing procedures, contract manufacturing arrangements, and inventory capacity are unknown.

Customization capabilityThe supplier explicitly describes itself as an expert in the design and production of custom optical components and crystals and states that it provides efficient communication and short lead times for custom production. Its specialized crystal-growth and coating capabilities further support customization in its stated product area.
