Import Equilateral Prisms — Buy in Bulk from Supplier in China

Equilateral prisms from Jilin Tianhua Opto Electrical Technology Development Co., Ltd. are precision-ground optical components with 60-degree angles and equal side lengths, typically manufactured from BK7 borosilicate glass or fused silica. The surface flatness is specified at λ/4 at 633 nm, with surface quality of 40-20 scratch-dig, and angles held within ±1 arcminute tolerance. These prisms are designed for applications requiring precise beam deviation, dispersion, or polarization control without introducing significant wavefront distortion.

The base materials follow standard optical glass specifications: BK7 meets ISO 10110-4 and has a refractive index of 1.5168 at 587.6 nm, while fused silica offers lower thermal expansion and higher transmission in UV ranges. Typical coatings include broadband AR for 400-700 nm or custom designs for laser lines such as 532 nm or 1064 nm. The prisms are polished to minimize scatter and internal inclusions, with edge chamfers to prevent chipping during handling. These characteristics align with industry norms for laboratory and industrial optical systems.

These prisms are commonly used in spectroscopy setups, laser beam steering, interferometers, and fiber optic alignment systems. Buyers include research institutions, laser equipment manufacturers, and medical device developers requiring reproducible optical performance. Trade terms are typically FOB Changchun or CIF port of destination, with packaging in foam-lined wooden crates. MOQ is not listed and must be confirmed directly with the supplier. Lead time for standard sizes is generally 2 to 4 weeks after order confirmation.

Jilin Tianhua Opto Electrical Technology Development Co., Ltd. is based in Changchun, Jilin Province, China, with a registered address at Torch Road 286, High Technology District. The company specializes in manufacturing precision optical components, including prisms, lenses, and mirrors for scientific and industrial use. Its profile confirms it is an imported supplier with harbor trust tier, but no details are provided on production capacity, staff size, or years in operation.

The listing does not state certifications, client names, or revenue figures. Response rate and average response time are recorded as zero, indicating no recent buyer inquiries have been answered. The supplier’s technical capability is inferred from the product detail, which reflects standard optical manufacturing tolerances. Buyers should request samples and test reports before placing bulk orders to verify alignment with their optical system requirements.
