This a precision aspherical lens that can condense the light into the range of diffraction limit when plane wave is incident. This is used when condensing the light of semiconductor laser into the parallel light and the parallel light into fiber.

◦Aspherical micro lens is formed by pressing the glass in a precision mold. Since this is non-abrasive forming, flange surface (FD) as a reference surface is provided on the lens.
◦It is designed that spherical aberration is minimized by consideration of a window of semiconductor laser (t=0.25mm).
◦Since outer diameter is small, it is possible to manufacture a compact optical system.

▶Please contact our International Sales Division when specifying anti-reflecting coating.
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶If using wavelength is significantly different from the design wavelength, large wave front aberration occurs.
▶Spherical aberration occurs when used without putting the LD window, collimated beam is not a plane wave.
▶If the lens direction is used reversely, he lens, it will not be able to be condensed into collimated beam or one point.
▶If there is slope when installing the lens, astigmatism and coma aberration can occur.
▶Please use the flange (reference plane) and use it after adjustment to be accurately perpendicular to the optical axis.
