DL-PNIR (Near infrared achromatic lens)
By setting the single lens bonding two lenses with wavelength dispersion of the refractive index is different, it can be smaller spherical aberration and chromatic aberration than the spherical single lens.
Specification
Attention
▶Please use achromatic lens when focusing to focus an image at infinity or when making parallel light from the one point of light source.It does not provide sufficient optical performance when used in such as short-range distance imaging.
▶There is a direction to the incident light parallel to the achromatic lens. A surface with a small radius of curvature is allowed to be incident parallel light from a rear surface (the surface on the arrow is pointing to). When it is incident parallel light from the opposite side, spherical aberration and chromatic aberration will occur and the focused spot size will increase.
▶When used in the visible region, spherical aberration and chromatic aberration increases. In addition, the transmittance decreases.
