SCHOTT High End Microscopic Glasses Enable Apochromatic “True Color”
New short flint glass types introduced to North American Market at SPIE Photonics West
January 27, 2009 (at Photonics West- San Jose, Calif.) – SCHOTT Advanced Optics (Booth #809) introduced to the North American market the special short flint glasses especially well suited for high apochromatic microscopy lenses at the SPIE Photonics West Exhibition.
As “true color” glasses, the N-KZFS4, N-KZFS5 and N-KZFS8 offer a unique pronounced deviation of the partial dispersion from the normal line. They are especially well suited for high end apochromatic lens design, almost eliminating chromatic aberration in state of the art microscopy applications.
They have been specially developed to highly transmit light in the blue violet range in combination with a low fluorescence at a 365 nm excitation wavelength. “True color” glasses are well suited for fluorescence microscopy, in which the fluorescence background of the optical components needs to be minimized to achieve an optimum contrast for the detection of the fluorophore labeled specimen.
Low fluorescence microscopy is widely used in the life sciences.
“SCHOTT offers a variety of optical glasses fulfilling tight specifications for optical position, dispersion and fluorescence, and these are especially well suited for sophisticated microscopy,” said Dr. Bernhard Hladik, Product Manager Optical Glass.
“True color” glasses are frequently used in combination with SCHOTT’s low dispersion Fluoro/Phosphate glass types like N-FK51A or N-PK51. Modern melting technologies enable SCHOTT to reduce the fluorescence of selected glass types, just as has been achieved for N-LASF44. SCHOTT can determine fluorescence for a wide range of excitation wavelengths between 200 nm and 1,500 nm.
“Customers can select the right material with specific characteristics for a broad range of biotech applications,” Dr. Hladik explained.
