UV Fused Silica Plano-Convex Cylindrical Lenses — GLH25 Series

From $78 USD

Product description

GLH25 plano-convex cylindrical lenses are made from UV fused silica and have one plane surface and one convex cylindrical surface. Their positive focal length focuses parallel or diverging beams into a line or changes an image aspect ratio.

Cylindrical lenses act in one direction and are suitable for one-dimensional magnification. A pair can reshape an elliptical beam or collimate and circularize laser-diode output; a single lens can focus a diverging beam onto a detector array.

For line focusing of a collimated beam, orient the curved surface toward the incident light. For collimating a line source, orient the plane surface toward the source.

Dimensions in mm unless otherwise stated.

Available per-model coatings: SWIR antireflection coating; average reflectance <0.5% over 900–1700nm; Uncoated; UV antireflection coating; average reflectance <0.5% over 250–450nm.

The source states a UV fused silica transmission range of 185 nm to 2.1 μm, low thermal expansion, high homogeneity, chemical resistance and low fluorescence.

Antireflection coatings reduce surface reflections and ghost images. Select the coating band specified for the individual model.

Rectangular cylindrical lenses can use adjustable cylindrical lens mounts; round versions can use adjustable round lens mounts. Mounts are separate components.

General specifications

Dimensions retain the source order for rectangular sizes and the Ø designation for round sizes. A slash (/) means the source does not supply that value; it is not zero. General tolerances are reproduced at series level; verify the individual model drawing for precision design. The 6.3 mm edge thickness for GLH25-025-300-SWIR includes its housing. SWIR models appear in the current source model table, but the source series curve set contains only uncoated and UV charts.
