IROptical Frequently Asked Questions

Question 1

What is CVD ZnSe and why is it preferred for IR optics?

Accepted Answer

CVD (Chemical Vapor Deposition) ZnSe is a high-purity form of Zinc Selenide produced through a controlled vapor deposition process. It offers several advantages for infrared optics:

Excellent transmission from 0.5-20μm wavelength range
  Low absorption coefficient (
  Homogeneous material properties throughout
  Minimal scattering and inclusion-free

These properties make CVD ZnSe the material of choice for CO2 laser optics and thermal imaging systems.

Question 2

What is the typical lead time for custom IR optics?

Accepted Answer

Lead times vary based on complexity and quantity:

Standard products: 2-4 weeks
  Custom dimensions: 4-6 weeks
  Complex custom optics: 6-8 weeks
  Expedited service: Available for urgent requirements

Contact our sales team for specific lead time estimates for your project.

Question 3

What surface quality can you achieve?

Accepted Answer

Our standard and custom surface quality specifications:

Standard: 40-20 scratch-dig
  Precision: 20-10 scratch-dig
  Ultra-precision: 10-5 scratch-dig (upon request)

Surface flatness typically achieves λ/10 @ 10.6μm, with λ/20 available for critical applications.

Question 4

Do you provide material certificates?

Accepted Answer

Yes, we provide comprehensive documentation with every shipment:

Material certificates with absorption measurements
  Dimensional inspection reports
  Surface quality verification
  Coating certifications (when applicable)
  Full traceability to raw material lots

Question 5

What coatings do you offer for ZnSe optics?

Accepted Answer

We offer a range of optical coatings:

AR/AR coatings: Optimized for 10.6μm (CO2 laser)
  Broadband AR: Multi-wavelength applications
  Protective coatings: For harsh environments
  Custom coatings: Designed for your specific wavelength

All coatings are applied in our in-house coating facility with full environmental testing.

Question 6
