Calcium Fluoride Double-Convex Lenses — GLH52 Series
From $136 USD
Request a quoteProduct description
Calcium fluoride (CaF₂) 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 IR1 antireflection coating; average reflectance <1.5% over 3–5μm; 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.
Schematic
Dimensions in mm unless otherwise stated.

Curves
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.
