UV Fused Silica Double-Concave Lenses — GLH24 Series
From $45 USD
Request a quoteProduct description
UV fused silica double-concave lenses have two concave surfaces of equal curvature and negative focal length. They diverge incident beams and are used for beam expansion, projection and increasing the focal length of optical systems, including Galilean beam expanders.
Double-concave lenses are generally preferred when the absolute conjugate ratio (object distance divided by image distance) is close to one. Plano-concave lenses are generally preferred for absolute magnification below 0.2 or above 5.
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.
UV fused silica provides transmission from 185 nm to 2.1 μm, with low thermal expansion, high homogeneity, chemical resistance and low fluorescence.
