Anamorphic Prism

The anamorphic prism is an optical element designed to correct the elliptical beam profile emitted by laser diodes, producing a circular output beam through differential magnification in orthogonal axes. Changchun Sunday Optoelectronics Co., Ltd manufactures this component for integration into laser systems across telecommunications, materials processing, and scientific instrumentation. The prism pair operates by expanding or compressing one axis of the beam relative to the other, with the magnification ratio determined by the prism angle and refractive index of the substrate material.

Construction typically employs BK7 or fused silica substrates, selected for transmission in the visible to near-infrared range (approximately 350 nm to 2.1 µm for BK7, 180 nm to 2.5 µm for fused silica). The anamorphic factor, defined as the ratio of magnifications in the two principal axes, is a critical design parameter commonly ranging from 2:1 to 6:1 for diode laser correction. Anti-reflection coatings, typically specified by wavelength range and residual reflectance (standard < 0.5% per surface, though < 0.2% is achievable with V-coating), are applied to minimise insertion loss. Surface quality is specified by scratch-dig per MIL-PRF-13830B or ISO 10110, with typical commercial grades of 40-20 or 60-40 for industrial applications and 20-10 or better for precision systems.

Buyers integrating anamorphic prisms into laser cutting heads, flow cytometers, or fibre-coupling optics should confirm the prism pair's wedge angle tolerance (typically ± 0.5 arcmin or tighter), beam deviation, and whether the supplier provides pre-aligned housings or unmounted prisms. Changchun Sunday Optoelectronics Co., Ltd operates from Donghuan Road in Changchun, Jilin Province, a region with established optical manufacturing infrastructure. The platform shows 0.00% response rate and zero average response hours, so buyers should anticipate delayed communication and consider direct outreach or representative engagement.

Changchun Sunday Optoelectronics Co., Ltd is located at No 9576 Donghuan Road, Changchun, Jilin Province, China, postal code 130000. The company holds a harbor trust tier on the platform, with a 0.00% response rate and zero average response hours recorded. These metrics indicate the supplier has not responded to platform inquiries, so buyers should not rely on platform messaging alone and should seek direct contact through the provided address or alternate channels.

The supplier's available profile does not state year of establishment, workforce size, annual revenue, factory floor area, or specific quality certifications. The Donghuan Road address places the company in Changchun, a city with historical strength in precision optics and photonics manufacturing due to institutional links with the Chinese Academy of Sciences. Buyers should verify whether Changchun Sunday Optoelectronics Co., Ltd operates its own polishing and coating facilities or sources substrates and coatings from third parties, as this affects lead time consistency and quality traceability.
