Import Beam Expander — Buy in wholesale FOB from Supplier in China

The beam expander from Wuhan Sintec Optronics Co., Ltd is a precision optical device built on a Galilean telescope design, which uses a negative lens and positive lens arrangement without an intermediate focus point. This configuration minimises spherical aberration and produces a collimated output beam with expanded diameter and reduced divergence. The unit is engineered for scientific and industrial laser applications where beam profile control and propagation stability are critical. Typical expansion ratios for this class of device range from 2x to 20x, with input and output apertures matched to common laser beam diameters of 1 mm to 12 mm. The optical elements are fabricated from industrial-grade substrates with multi-layer anti-reflection coatings to maximise transmission and minimise ghost reflections.

The optical train employs precision-mounted lens elements in a mechanically stable housing, with adjustment mechanisms for collimation and pointing alignment. Standard materials include fused silica or BK7 glass for the positive objective lens, and high-index optical glass for the negative input element, depending on the wavelength range and power handling requirements. Typical surface figure accuracy is lambda/4 at 633 nm, with scratch-dig specifications of 40-20 or better for industrial applications. The housing is typically constructed from anodised aluminium or stainless steel to provide thermal stability and resistance to laboratory environments. Sealed versions may include nitrogen purging ports to prevent moisture condensation on optical surfaces.

This beam expander serves telecommunications infrastructure, materials processing with CW or pulsed lasers, scientific research laboratories, and medical device manufacturing. Buyers include OEM laser system integrators, university research groups, and industrial automation firms. The supplier notes wholesale availability with adjustable minimum order quantities; exact figures are not stated and should be confirmed directly with Wuhan Sintec Optronics. Standard Incoterms mentioned include FOB and CIF, though specific port and freight arrangements require direct negotiation. Buyers should verify wavelength compatibility, expansion ratio, and mounting thread specifications against their source laser parameters before ordering.

Wuhan Sintec Optronics Co., Ltd is located at 1 Lingjiashan Road South, Optics Valley Avenue, Wuhan 430073, Hubei Province, China. The supplier operates within the Wuhan East Lake High-Tech Development Zone, a cluster known for photonics and optoelectronics manufacturing. The company is classified at harbour trust tier with zero recorded response rate and zero average response hours in the available data, which indicates that communication patterns are not established from this dataset. The supplier is marked as an imported-tier vendor, suggesting established export capability or registration status.

The supplier's listing emphasises precision optical devices for scientific and industrial markets, with particular attention to the Galilean telescope architecture. No verified factory size, year of establishment, revenue figures, or named client references appear in the source data. The address places the company within China's major optoelectronics corridor, though proximity to other firms in Optics Valley does not confer specific manufacturing credentials. Buyers should request ISO certification status, quality management documentation, and prior customer references directly from Wuhan Sintec Optronics, as these are mentioned as potentially applicable but not confirmed in the available record.
