Zinc Selenide Double-Convex Lenses — GLH72 Series

From $204 USD

Product description

CVD laser-grade zinc selenide (ZnSe) double-convex lenses have positive focal length and two convex surfaces. The source describes use in imaging relay systems and finite-conjugate imaging, with object and image on opposite sides of the lens. Choose a model by its listed focal length, diameter, thickness and coating, then select a quantity to request a quotation.

Available source-listed coating options include IR2 antireflection coating; average reflectance <1.5% over 8–12μm; Uncoated.

The source states that an uncoated surface reflects about 4% of incident light and that antireflection coatings can increase transmission and reduce ghost images.

Dimensions in mm unless otherwise stated.

The source states a transmission range of 600 nm to 16 μm for ZnSe.

Handle with gloves, avoid direct contact, and wash hands after handling, as directed by the source.

Technical notes

Thin-lens approximation stated in the source (signed surface radii): f = (R1 × R2) / ((n − 1) × (R2 − R1)); use a thick-lens model for precision design.

Review the material, dimensions and other specifications listed for the individual model. Check any available curves against the model's stated operating range.

Illustrations and printable specification summaries are reference information, not manufacturing drawings. Confirm technical suitability and final requirements with your quotation.
