Import Achromatic Wave Plate — Buy in wholesale FOB from Supplier in China

United Photonics Technology manufactures achromatic wave plates that deliver constant phase shift across broad wavelength ranges by bonding crystal quartz with magnesium fluoride. The design eliminates the chromatic dispersion problems of single-material wave plates, making these components suitable for tunable lasers and multi-line laser systems where wavelength varies. Retardation tolerance is specified at better than λ/100 across the entire operational range, with wavefront distortion held to λ/4 at 632.8nm. Dimension tolerance is +0/-0.2mm, indicating precision machining suitable for drop-in mounting in standard optical assemblies.

The achromatic construction relies on the differing birefringent properties of crystal quartz and MgF2 crystal, materials selected for their complementary dispersion characteristics. Crystal quartz provides high birefringence and excellent UV transmission, while magnesium fluoride extends transparency deeper into the ultraviolet and offers superior durability. The two materials are typically contact-bonded or optically contacted, with the relative thicknesses calculated to produce the desired quarter-wave or half-wave retardation over the design bandwidth. Flat response across the spectrum reduces the need for multiple single-wavelength wave plates in instruments using broadband sources.

These wave plates serve spectroscopy, metrology, and laser system integrators who require stable polarization control without component swapping. Typical buyers include OEMs building tunable laser systems, research laboratories running multi-wavelength experiments, and manufacturers of polarimetric sensors. United Photonics Technology operates from Fuzhou, Fujian Province, with a harbor trust tier and no recorded response data. Buyers should confirm availability, exact wavelength ranges, and coating specifications directly with the supplier before committing to volume orders.

United Photonics Technology is located at 2nd Floor, Building 6, No.26 Changlong Middle Road, Tieling Industrial District, Minhou, Fuzhou, Fujian Province, 350100, China. The company holds a harbor trust tier on the platform, which represents a baseline verification level. No response rate or average response time data is available, meaning buyers should anticipate potential communication delays and plan sourcing timelines accordingly. The listing provides no information about manufacturing floor space, employee count, annual revenue, or year of establishment.

The supplier specializes in precision optical components, specifically achromatic wave plates fabricated from crystal quartz and magnesium fluoride. Their product claims center on retardation precision and wavefront quality rather than volume production capacity. Buyers should note that the address places the company in Fuzhou's industrial district, a region with established optoelectronics manufacturing infrastructure. No certifications, client references, or export experience is stated. Direct inquiry about quality control protocols, inspection equipment, and previous supply relationships remains essential before technical qualification.
