Zinc Selenide (ZnSe) Lenses
Zinc selenide transmits from the visible/near-IR through the mid-infrared, and its low absorption at 10.
Share requirements, quantities and a drawing if available. Specifications and supply terms require confirmation.
Overview
Zinc selenide transmits from the visible/near-IR through the mid-infrared, and its low absorption at 10. 6µm has made it a historically standard material for CO2-laser lens optics — the same material property covered on the ZnSe Optical Windows page, here in lens form. Procurement review should center on focusing or collimating CO2-laser or infrared energy while managing ZnSe coating and handling constraints.
Key Selection Points
- Established material for CO2-laser (10.6µm) focusing optics
- Wide transmission range spanning visible/near-IR through mid-IR
Applications

Lens Geometry & Selection Guide
This module explains how lens geometry changes the selection path and the information required from the optical design. For Zinc Selenide (ZnSe) Lenses, the module focuses on focusing or collimating CO2-laser or infrared energy while managing ZnSe coating and handling constraints.
- Show surface orientation, optical axis and conjugate or beam condition in the drawing.
- Include focal length, prescription and aberration targets with the enquiry for feasibility review.
- State tolerance and manufacturable-range requirements on the drawing for review.
- Product-specific review: connect wavelength and beam use with ZnSe grade and document the trade-off against germanium lenses.

Frequently Asked Questions
Is this suitable for CO2 laser cutting/engraving?
ZnSe is a long-established material choice for CO2-laser (10. 6µm) lens optics. Confirm your exact power/duty requirements when requesting a quote.
Which specification should be fixed first for Zinc Selenide (ZnSe) Lenses?
Begin with wavelength and beam use. It determines how lens geometry and focal requirement and ZnSe grade should be evaluated before the mechanical details are finalized.
When is Zinc Selenide (ZnSe) Lenses a better fit than germanium lenses?
Choose between them by testing the requirement for focusing or collimating CO2-laser or infrared energy while managing ZnSe coating and handling constraints. If that requirement is absent, the comparison product may provide a simpler procurement path.
What should an RFQ for Zinc Selenide (ZnSe) Lenses include?
State beam wavelength, beam diameter, focus or collimation objective and power context for review. Also include quantity, drawing revision and the required acceptance evidence. Final availability is confirmed during quotation.
Which details for Zinc Selenide (ZnSe) Lenses still require supplier verification?
Actual material and coating availability, dimensional limits, tolerances, inspection reports, MOQ and lead time cannot be inferred from this page and must be confirmed against the RFQ.
