Visible Spectrum Achromat 49.4mm Focal Length
ATL-30-50PY2
Visible spectrum achromats are air spaced achromatic triplets or doublets for lasers in the visible spectrum or white light applications. The elements are made of crown glass of low dispersion and flint glass of high dispersion.
◦These lenses have been optimized for achromatic and spherical aberrations and coma for the 3 wavelengths; blue (486.1nm), green (546.1nm) and red (656.3nm). They are coated with a broadband multi-layer anti-reflection coating for 400 − 700nm.
◦Air spaced design allows high power laser applications which includes YAG second harmonic wavelength (532nm).
◦The triplets with F-numbers ≧2 and doublets with F-numbers ≧3 are designed to have each spot size equal to the diffraction limited spot size and very ideal for a Gaussian input beam.
