Knight Optical’s Achromatic Doublets for Light Engines

12 Nov 2019

Knight Optical offer a range of Stock Achromatic Doublet Lenses for use within Light Engines.

Light engines are used for applications such as fibre optic lighting displays and in diagnostic tools like western blots and polymerase chain reaction systems. These Light Engines are typically able to produce changing colour displays. Within the light engine are a range of lenses and filters. The lenses help to homogenise and collimate the light, ensuring for a crisp high-quality beam output.

Achromatic Doublets are typically used in light engine systems and correct for chromatic aberrations which exist in singlet lenses. This is when different wavelengths of light refract at different rates. The doublet lens helps to correct this by facilitating the focusing of the light to the same point. This is especially important in light engines which typically generate white light.

Knight Optical can supply competitive quotes for custom positive and negative achromatic doublets. These achromatic doublets can also come in the form of aspheric lenses.
