Zinc selenide granules are a high-purity II-VI compound semiconductor material with the chemical formula ZnSe. The product appears as yellow to orange-red crystalline granules featuring a sphalerite cubic crystal structure and a direct bandgap of approximately 2.7 eV. It exhibits outstanding broadband infrared transmittance, high laser damage threshold, efficient photoluminescence properties, and excellent chemical stability, making it a key foundational material for fabricating infrared optical components, lasers, and optoelectronic devices.
We offer high-quality zinc selenide granules in multiple purity grades and particle size specifications, with professional optical-grade custom processing available. Contact us for tailored solutions.

Infrared Optics & Thermal Imaging: Manufacture high-performance windows, lenses, and coupling mirrors for infrared thermal imagers, night vision systems, and laser optics.
Laser Technology & Nonlinear Optics: Serves as substrate or nonlinear crystal material for tunable lasers and optical parametric oscillators in the mid-infrared band.
Optoelectronics & Display Devices: Used in core functional layers for blue-green laser diodes, light-emitting diodes, and thin-film electroluminescent displays.
Advanced Ceramics and Functional Materials: Used to prepare high-damage-threshold, high-temperature-resistant infrared-transparent ceramics, or as special additives to enhance material properties.
Q1: What is the difference between ZnSe particles and ZnSe ingots in application?
A1: They differ in morphology and processing pathways. Particles serve as raw materials for regrowth or hot-press sintering into optical components; ingots are finished or semi-finished products that can be directly cut and polished for use.
Q2: Why is ZnSe highly regarded in infrared applications?
A2: Its core advantages lie in an exceptionally broad infrared transmission range, minimal optical absorption, and high laser damage threshold, making it an ideal choice for high-performance infrared windows and laser components.
Q3: How should the product be stored?
A3: Store in sealed containers in a dry, light-protected environment, away from acids, alkalis, and oxidizing agents to prevent surface contamination or corrosion that could compromise optical performance.
Q4: Is it safe to use?
A4: Selenides possess some toxicity. Avoid inhaling dust during handling. Work in well-ventilated areas and wear appropriate protective equipment.
