Alrad has signed a UK distribution agreement to market Optometrics' range of interference filters and other optical components.

Optometrics is a worldwide supplier of optical components including gratings, lenses, filters, laser optics, monochromators, and specialised optical systems and software. Optometrics’ interference band pass filters are wavelength selectors that allow the transmission of a pre-determined wavelength, while rejecting or blocking other wavelengths. Interference filters are widely used in instrumentation for clinical chemistry, environmental testing, colorimetry, elemental and laser line separation, flame photometry, fluorescence and immunoassays.

Optometrics produces thousands of filters specified by and designed for other instrument manufacturers. If its standard filters do not conform to user requirements, Optometrics can design and manufacture filters to specific performance and dimensional specifications.
