Detail Information

Custom ZnSe Zinc Selenide Infrared Optical Window For CO₂ Laser & Infrared Detection

 
Felix Glass ZnSe selenide infrared window is made of high-purity zinc selenide crystal, featuring ultra-wide infrared transmission range from 0.6μm to 18μm, with extremely low absorption loss at 10.6μm CO₂ laser band, which is the core protective window material for industrial CO₂ laser equipment.
 
We provide round, square and rectangular ZnSe blanks with customizable size, thickness and edge chamfer. Double-sided anti-reflection AR coating for infrared band can be deposited to raise infrared transmittance above 95%. The material features stable thermal performance, low thermal expansion coefficient, not easy to deform under long-time laser irradiation.
 

Core Optical Specifications

 
- Raw Material: High purity zinc selenide single crystal
- Transmission Range: 0.6 ~ 18 μm
- Key Band Transmittance: ≥70% uncoated, ≥95% after IR AR coating
- Standard Shape: Round, square, rectangle, special irregular outline OEM
- Surface Quality: 60-40 scratch-dig industrial grade, 20-10 high precision optional
- Custom Process: Edge chamfer, single/double side infrared AR coating
 

Core Product Advantages

 
1. Excellent transmittance at 10.6μm CO₂ laser, low energy loss for laser cutting/marking machine
2. Wide infrared spectrum coverage, fit thermal imager, infrared temperature sensor and FTIR spectrometer
3. Stable thermal property, resistant to laser thermal radiation, long service life
4. Multiple shape & size customization, match different laser cavity and infrared sensor housing
5. Optional IR anti-reflection coating to reduce surface reflection and improve light efficiency
6. Small sample trial and mass industrial batch orders both acceptable, full spectral test report provided
 

Typical Application Scenarios

 
- CO₂ laser cutting, engraving, marking machine output protective window
- Non-contact infrared temperature measurement sensor optical substrate
- Laboratory FTIR Fourier transform infrared spectrometer optical window
- Industrial infrared gas absorption detection equipment
- Thermal imaging camera, infrared night vision optical components
- Medical infrared body temperature detection optical window
 

OEM Manufacturing Capability

 
We provide full one-stop ZnSe processing including crystal blank cutting, ultra-precision parallel polishing, vacuum infrared AR coating deposition, edge chamfer treatment, dust-free packaging. Custom size and coating parameters are supported, every ZnSe window passes transmittance and surface defect inspection before delivery.
 

Standard FAQ

 
1. Why choose ZnSe for CO₂ laser window?
ZnSe has ultra-low absorption at 10.6μm, high infrared transmittance, better thermal stability than other infrared crystals.
2. Can I customize anti-reflection coating for specific infrared wavelength?
Yes, we customize AR coating matched to 2~14μm infrared band according to customer working wavelength.
3. What shapes of ZnSe window can you produce?
Round, square, rectangular and special irregular shapes are all available for OEM customization.
4. What’s the difference between coated and uncoated ZnSe window?
Uncoated ZnSe has around 70% transmittance; IR AR coated one reaches over 95% transmittance, less energy loss.
5. Do you supply small quantity samples for laser equipment R&D test?
We accept 1 piece small sample order and provide complete spectral transmittance test certificate for each batch.
