Heteromorphic Window
The heteromorphic window offered by Tian Cheng Optics Co., Ltd. is a precision‑engineered optical component made from either BK7 optical glass or synthetic sapphire (Al2O3). Available diameters range from 1 mm to 500 mm with a diameter tolerance of +0 mm / -0.02 mm and a thickness tolerance of +/-0.01 mm. Surface quality is specified to 10-5 and the surface figure to λ/10, while parallelism is held within 1 minute of arc. The windows can be supplied uncoated or with anti‑reflection, high‑reflectance or beamsplitter coatings as required.
BK7 provides a refractive index of approximately 1.517 at 587 nm and transmits from 350 nm to 2 µm, whereas synthetic sapphire delivers higher hardness and transmission into the infrared range, typical for demanding laser and imaging systems. The product family also includes variants made from CaF2, MgF2, ZnSe, ZnS and fused silica, each selected for specific wavelength or thermal properties. In the optics industry, such windows are classified as custom‑shaped components and are fabricated to meet +/-0.02 mm dimensional tolerances and λ/10 surface figure as a standard practice. The supplier emphasizes high surface quality and minimal beam deviation to meet laboratory and industrial performance criteria.
Typical end users are OEMs that integrate the windows into projection optics, scientific measurement instruments and infrared imaging rigs. Buyers usually request bulk quantities with packaging in clean‑room‑rated boxes, and trade terms are negotiated per order with incoterms such as FOB Shanghai or CIF Hong Kong. Prospective importers should confirm the exact coating type, material grade and tolerance sheet before finalising the purchase.

Sourcing Heteromorphic Window from Tian Cheng Optics Co., Ltd. - China Import Guide
Before placing an order, importers should obtain the supplier’s material data sheet confirming whether the window will be fabricated from BK7 glass or synthetic sapphire and verify the exact coating type required for the application. Request the dimensional tolerance sheet that lists the agreed diameter and thickness tolerances, as well as the surface quality and figure specifications. Because no formal certifications are listed, ask for an optical performance test report to substantiate the 10-5 surface quality and λ/10 figure claims.
Logistics should be clarified early; buyers typically negotiate FOB Shanghai or CIF Hong Kong depending on their shipping strategy, and they must confirm the port of loading and the expected lead time, which the supplier does not disclose publicly. It is prudent to ask for an estimated production schedule, especially for custom‑shaped windows where machining cycles can extend lead times. Payment terms are usually agreed per contract, with common practice of a 30 % deposit and balance against shipping documents.
When the goods arrive, importers should arrange for a third‑party optical inspection to verify surface quality, coating uniformity and dimensional accuracy against the supplied tolerance sheet. Request the supplier’s Mill Test Report and a full optical test certificate documenting transmission, refractive index and surface figure measurements. Retaining these documents facilitates customs clearance and provides a reference for any warranty claim should the windows not meet the agreed specifications.
