Biotech Optics

!%Edmund Optics%! has released its Precision Biotech Optics catalog, which features in-stock products for researchers and developers in fields ranging from DNA sequencing to microscopy to biomedicine. It presents aspherized achromat lenses for high-precision focusing applications, including retinal photocoagulation; broad-wavelength lens systems, such as UV-NIR triplets, for use in two-photon excitation microscopy; and stable and sharp cutoff filters with high damage thresholds, such as ultrasharp long-pass filters for Raman spectroscopy.
