Detail Information

Custom Zinc Selenide ZnSe Infrared Optical Window

Felix Glass Zinc Selenide (ZnSe) infrared window is high-purity polycrystalline infrared optical substrate specially developed for mid-far infrared and CO2 laser systems. It features ultra-high transmittance within 0.6~18μm infrared wavelength band, with excellent optical performance at the 10.6μm CO2 laser core wavelength, making it the standard optical window material for industrial carbon dioxide laser equipment.

We adopt high-purity CVD-grown ZnSe crystal raw material, with stable physical and chemical properties, low thermal absorption and low thermal distortion. Optional single-sided or double-sided anti-reflection coating can further reduce infrared reflection loss and improve laser transmission efficiency. The substrate supports long-term stable operation under continuous laser irradiation and high temperature environment.

Core Product Advantages

Ultra-wide infrared transmission spectrum covering visible light to far infrared, peak transmittance over 97% at 10.6μm CO2 laser band.

Low thermal absorption coefficient, effectively avoid thermal lens effect and surface deformation during long-time laser work.

High mechanical uniformity, low internal stress, high scratch resistance optical surface with strict 40/20 scratch-dig grade standard.

Full customization support: outline size, substrate thickness, edge chamfer treatment, 10.6μm AR anti-reflective coating.

Stable chemical inertness, resistant to moisture and weak acid, suitable for complex industrial workshop environment.

Each finished ZnSe window will pass infrared spectral testing, dimensional inspection and surface defect detection before delivery.

Custom Processing Options

1. Shape Customization: Custom square, rectangle, circular wafer and irregular special outlines per customer engineering drawing.

2. Thickness Customization: 1mm to 10mm optional, strict thickness tolerance ±0.02mm.

3. Surface & Coating Customization: Uncoated bare ZnSe substrate or double-sided AR anti-reflection coating optimized for 10.6μm CO2 laser.

4. Edge Treatment: Raw edge, 0.5~2mm chamfer polished edge, anti-oxidation passivation edge for assembly.

5. Size Customization: Diameter or side length from 5mm to 300mm available for small laser head and large-format laser cutting equipment.

Typical Application Scenarios

This high-purity ZnSe infrared window is the core optical component of all kinds of CO2 laser equipment. It serves as protective output window for CO2 laser cutting machines, laser marking engraving equipment and laser welding systems. Besides, it can be applied to thermal infrared imaging detectors, mid-infrared spectral analysis instruments, industrial temperature measurement cameras and medical infrared diagnostic optical modules.

FAQ

1. What is the core advantage of ZnSe window for CO2 laser?

ZnSe material has extremely low light absorption at 10.6μm, avoiding thermal deformation, and maintains high transmittance for stable long-time laser output.

2. Can I customize anti-reflective coating on the ZnSe window surface?

Yes, we provide single-sided and double-sided AR coating specially optimized for 10.6μm CO2 laser to reduce surface reflectivity below 0.5%.

3. What shapes and sizes can be customized for ZnSe infrared window?

Round, square and rectangular outlines are all available, customizable size range from 5mm to 300mm, thickness adjustable from 1mm to 10mm.

4. Do you offer sample testing service and bulk mass supply?

Free prototype samples are available for laser performance testing. We support small trial orders and large volume mass production, with full optical inspection for every finished ZnSe window piece.
