Optical Glass Plano-Convex Lenses
Optical-glass plano-convex lenses have one flat surface and one convex surface. This category covers the GLH11 and GLA11 series families; dimensions and coating options are specified for each series.
Use the GLH11 or GLA11 family to reach the appropriate model table. The GLA11 branch also separates coating options, making it useful to identify the operating band before selecting the focal length and mechanical dimensions.
Choosing Optical Glass Plano-Convex Lenses
Compare the series specifications directly; do not assume the same nominal focal length implies identical thickness or coating.
Choose diameter from the beam aperture and holder, then check back focal length against the available spacing.
Include wavelength, intended surface orientation and object or beam geometry when asking for a substitution between series.
Use the optical-parameter guide to distinguish focal, aperture and surface specifications.GLA11 standard models use N-BK7. Non-standard GLA11 models include N-BK7, ZF and H-ZLAF2A; check the material listed for each model. GLH11 remains a separate series with its own specifications.
