Precision designed for 1:1 imaging
Surfaces uncoated
Tolerances: Focal length f' : ± 2 %, Image distance s' : ± 2 %
Two equal radii of curvature

Our singlets are also available with the following coatings:
VIS range (ARB2: R < 0.5 % per surface, AOI = 0°, λ = 450 - 700 nm).
NIR range (ARB2: R < 0.5 % per surface, AOI = 0°, λ = 725 - 1050 nm).
Nd:YAG fundamental (ARHS: R < 0.2 % per surface, AOI=0°, center wavelength 1064 nm)
All singlets can be found in the database of our Optics Software WinLens Ϯ, please look at www.winlens.de.
ZEMAX files can be downloaded in the document area
