Beam Expander - What You Should Know About It

What's an achromatic lens?

An achromatic lens or Achromat is a lens that's produced with the goal of restricting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses have been adjusted to bring two wavelengths to focus in precisely the same plane.

What is a chromatic aberration?

Chromatic aberration, too Called chromatic distortion and spherochromatism, is a result generated from dispersion due to the failure of a lens to focus all colours to the identical convergence point. When white light passes through glass, then each wavelength element of the light is separated and focuses at several points onto a plane. Chromatic aberration seem as "fringes" of color along boundaries that separate bright and dark parts of the image, due to every color in the optical spectrum can't be focused at a single common point.

What is a spherical aberration?

Spherical aberration is an Optical effect which occurs in a lens due to the increase of refraction of light rays when it strikes the lens. The produced image will end in imperfection. Both this phenomenon signifies that the lens isn't working normally.

Achromatic double lenses

Achromatic doublet is the Most frequent sort of achromat lens. Generally, it consists of two separate lenses made from glasses with different amounts of dispersion.

Achromatic lenses utilize 2 Different glass substances of distinct dispersion to refocus the individual wavelengths of light to one focal point.

Achromatic lenses can be Used to adjust the line of sight and focus laser beams. These lenses are widely utilized in high quality digital imaging, surface inspection, and spectroscopy applications.
