❓ SWIR Lens FAQs

Q1: Can I use visible lenses for SWIR?
⚠️ No. They lack IR transparency and introduce chromatic aberrations.

Q2: Do you support hyperspectral lens design?
✅ Yes. We cover 1.0–2.5 µm ranges with matched coatings and precision MTF.

Q3: Which materials are available?
🧪 ZnSe, Sapphire, Ge, Si, ZnS, Chalcogenide glass.

Q4: Typical lead time?
🚚 Stock: 1–2 weeks; Custom: ~4–6 weeks.

Q5: Environmental ruggedness?
🛡️ Yes. Lenses rated –40°C to +85°C, optional IP65 sealing.
