UV Fused Silica Plano-Concave Lenses — GLH23 Series
From $45 USD
Request a quoteProduct description
UV fused silica plano-concave lenses have one flat and one concave surface and a negative focal length. They turn collimated incident light into a diverging beam with a virtual focus and are commonly used in Galilean beam expanders. Orient the concave surface toward the incident beam, with the plane surface toward the focal plane.
Plano-concave lenses provide negative spherical aberration and can compensate aberrations from other lenses in an optical system. For source-recommended conjugate magnitudes below 0.2 or above 5, plano-concave lenses are generally selected; double-concave lenses are often used between these values.
Available coatings: Uncoated; UV antireflection coating; average reflectance <0.5% over 250–450nm; A-band antireflection coating; average reflectance <0.5% over 350–700nm; B-band antireflection coating; average reflectance <0.5% over 650-1100nm; C-band antireflection coating; average reflectance <0.5% over 1050-1700nm.
Schematic
Dimensions in mm unless otherwise stated.
Antireflection coatings reduce surface reflections and ghost images. An uncoated glass surface reflects approximately 4% of incident light; coatings on both surfaces improve transmission in multi-element systems.
UV fused silica provides transmission from 185 nm to 2.1 μm, with low thermal expansion, high homogeneity, chemical resistance and low fluorescence.
