Optical Windows
These optical windows are precision components manufactured from BK7 borosilicate crown glass, Calcium Fluoride (CaF2), and Fused Silica (FS), each material selected for its transmission properties across UV, visible, and IR spectra. The supplier offers bespoke windows tailored to specific wavelength requirements, with surface quality and flatness critical for applications in laser systems, spectrometers, and thermal imaging equipment. AR coating options are available to enhance performance in demanding optical environments.
BK7 glass provides broad transmission from 350 nm to 2 µm, making it a standard choice for visible and near-IR applications, while CaF2 extends transmission into the deep UV (down to 180 nm) and IR (up to 8 µm), ideal for excimer lasers and medical diagnostics. Fused Silica offers exceptional UV transparency and thermal stability, typical for high-power laser systems. Each material undergoes rigorous quality control to ensure low scatter, high homogeneity, and minimal absorption, meeting typical industry standards for optical-grade substrates.
These windows serve OEM supply chains in scientific research, defence, and industrial sectors where precision and reliability are non-negotiable. Buy in bulk for integration into spectrometers, medical devices, or aerospace instrumentation, with packaging designed to prevent surface contamination during transit. The supplier provides material certification and traceability documentation, ensuring compliance with international optical component standards for industrial applications.

Sourcing Optical Windows from Tianjina tengteng Industrial And Trading Co., Ltd. - China Import Guide
Before ordering, verify the exact material composition and transmission range required for your application, as each material (BK7, CaF2, Fused Silica) offers distinct optical properties. Confirm whether AR coatings are necessary and specify the target wavelength range to ensure compatibility with your system’s performance requirements. Request the supplier’s material certification to validate that the windows meet your precision standards.
Discuss logistics details such as shipping methods, lead times, and Incoterms to align with your project timeline. Optical windows are sensitive to surface damage, so ensure the packaging and handling procedures meet international standards for fragile, high-precision components. Clarify whether the supplier can accommodate bulk orders and if they offer flexible MOQs for custom specifications.
Conduct quality checks upon receipt, focusing on surface quality, flatness, and coating integrity. Use a wavefront interferometer or similar tool to verify flatness specifications like λ/10 at 632.8 nm, and inspect for scratch-dig defects under controlled lighting. Request a certificate of conformance to confirm the windows meet the agreed-upon optical and dimensional tolerances before integration into your equipment.
