355 nm Laser-Grade Fused Silica Plano-Convex Lenses — GLH21-V355 Series
From $222 USD
Request a quoteProduct description
GLH21-V355 plano-convex lenses have one flat surface and one convex surface, with a positive focal length. They focus collimated light, collimate point sources and reduce beam divergence.
The series uses HPFS 7980 fused silica for laser applications. V-type antireflection coatings minimize reflection over a narrow wavelength band; select the coating for the laser wavelength and angle of incidence.
To reduce spherical aberration when focusing a collimated beam, orient the curved surface toward the incoming light. When collimating a point source, orient the flat surface toward the source.
Schematic
Dimensions in mm unless otherwise stated.
Options in this family cover 355 nm, 532 nm, 1064 nm and the dual wavelengths 532/1064 nm at a specified angle of incidence of 0°.
The model specifications list a laser damage threshold of 5J/cm²@355nm,20ns. This rating applies to the stated wavelength and pulse duration; it must not be generalized to other laser conditions.
Select mounts appropriate to the lens diameter and curvature. The source describes SM1 (1.035″-40) and SM2 (2.035″-40) mounts; mounts and other components are supplied separately.
The schematic is for reference only and must not be used as a manufacturing drawing. Refer to the individual model specifications and drawing for engineering decisions.

Curves
Technical notes
Paraxial thin-lens estimate: f ≈ R / (n − 1), where R is the curved-surface radius and n is the refractive index at the relevant wavelength. Use each model’s listed focal length and back focal length.
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.
