Detail Information

Factory Supply CVD ZnSe Plano-Convex Spherical IR Window Lens (Square & Round Dual Sizes Optional)

Felix Glass plano-convex ZnSe lens window is an integrated optical component combining infrared focusing lens and protective window, manufactured from high-purity CVD polycrystalline zinc selenide crystal. We provide two mainstream outline options: square rectangular and round circular to match different optical module installation structures.

ZnSe substrate supports ultra-wide continuous transmission from 0.5μm visible red light to 22μm long-wave infrared, the exclusive material for high-power 10.6μm CO₂ industrial laser and dual-spectrum thermal imaging equipment. The plano-convex spherical structure features flat plane as external protective surface, convex surface to converge infrared laser beam. Custom multi-spectrum broadband AR coating is deposited on both surfaces, showing iridescent interference color under light, improving infrared transmittance and protecting soft ZnSe crystal from scratch and oxidation.

The integrated lens-window design replaces separate lens + window two-piece structure, simplifies optical assembly and reduces equipment production cost.

- Aerial infrared multi-spectral detection optical assemblies

OEM Manufacturing Capability

We provide full one-stop CVD ZnSe optical processing including large crystal blank cutting, ultra-precision plano-convex spherical polishing, multi-spectrum broadband AR coating, square/round edge deburring, strict multi-wavelength spectral transmittance testing and laser damage threshold inspection.

Prototype sampling, small-batch trial production and factory mass supply are supported. Every ZnSe plano-convex window lens (square or round) is fully tested to meet customer-specified spectral, dimensional and laser resistance requirements before delivery.

FAQ

1. What shape options are available for this ZnSe lens window?

We supply square rectangular and round circular two standard outlines, all dimensions, thickness and focal length can be customized according to customer optical system drawings.

2. What is the advantage of integrated ZnSe lens window vs separate lens + window?

It combines focusing lens and protective window into one part, reduces parts quantity, simplifies optical assembly and lowers equipment manufacturing cost. Square fits compact flat modules, round matches standard circular laser cutting heads.

3. Why ZnSe is the standard material for CO₂ laser optics?

ZnSe has extremely low absorption at 10.6μm, high laser damage threshold, stable under continuous high-power laser irradiation, and wide visible-infrared transmission for auxiliary alignment light.

4. What equipment matches square & round ZnSe plano-convex infrared window lens?

It fits CO₂ laser cutting/marking machines, dual-spectrum vehicle night vision cameras, industrial multi-band temperature measuring equipment and laboratory infrared spectrometers.

5. Do you provide factory mass supply for ZnSe infrared optical components?

We offer factory direct bulk supply, small trial samples and OEM customization, all square & round ZnSe lens windows pass full spectral and laser resistance inspection before shipment.
