Zinc Selenide Window (ZnSe) Dia. 25 mm x Thk. 3 mm, Uncoated FAQs

Q1: What are the key material properties of Zinc Selenide Window (ZnSe) Dia. 25 mm x Thk. 3 mm, Uncoated?

A1: Zinc selenide (ZnSe) is known for its broad transmission range, typically from about 0.6 μm to 16 μm, making it ideal for infrared applications such as laser systems and thermal imaging. Its refractive index is approximately 2.4 at 10.6 μm, providing efficient light transmission. The material offers high thermal conductivity and relatively low bulk absorption. However, it is relatively soft, which requires careful handling to prevent scratches or other surface damage.

Q2: How should this product be handled and stored?

A2: Due to its softness and susceptibility to scratches, ZnSe windows should be handled only with clean gloves to avoid contamination from skin oils or particles. Keep the window in a protective case or tissue-lined container when not in use to prevent accidental contact with hard surfaces. Store it in a controlled environment with stable temperature and low humidity to prevent moisture absorption, which can negatively affect surface quality.

Q3: Which quality standards and certifications apply to Zinc Selenide Window (ZnSe) Dia. 25 mm x Thk. 3 mm, Uncoated?

A3: These windows typically adhere to MIL-PRF-13830 for scratch and dig criteria, ensuring minimal surface defects. They may also be manufactured under ISO 9001 quality management systems, demonstrating strict production controls and consistent quality. Some suppliers provide compliance with RoHS and REACH directives, confirming minimal hazardous substances. Users can request test reports, interferometric data, or certification of conformance to confirm the window meets relevant industry and application-specific standards.

1. Manufacturing Process

The production of a Zinc Selenide Window (ZnSe) with a diameter of 25 mm and a thickness of 3 mm begins with the careful formation of high-purity crystalline ZnSe. Using specialised furnaces, the raw ZnSe material is melted and formed into uniform ingots under tightly controlled temperature conditions. These ingots are then sliced into circular blanks, ensuring minimal surface defects and optimal diameter consistency.

Skilled technicians next subject each blank to precision grinding and polishing procedures to achieve the desired 3 mm thickness and superior surface quality. Throughout this stage, meticulous attention is paid to limiting contamination and preserving the material’s clarity, making the final uncoated window well-suited for infrared applications requiring minimal scattering or absorption.

2. Applications in Advanced Industries

Expanding capabilities in optical sensing and imaging make ZnSe windows an ideal choice for research facilities and high-tech manufacturing sites. The uncoated, 25 mm diameter window provides consistent infrared transmission, enabling accurate measurements for laser-based systems, thermal cameras, and other specialised instrumentation.

Non-contact temperature monitoring and advanced spectroscopy setups also benefit from this window’s performance in hostile environments. Its durability, combined with the ability to transmit across a broad infrared range, allows industries such as semiconductor processing, aerospace engineering, and medical device development to rely on this ZnSe component for critical imaging and analytical tasks.
