Remark -
Attention Focusing Lenses can be used to bring an object at infinity into focus, or to convert a point light source into a collimated light. When used for imaging at close distance, sufficient optical performance will not be provided. Focusing Lenses have a designated incident side. Be sure to input a collimated light from the upper side of the engraved lettering on the lens barrel. When reversed, chromatic and spherical aberrations increase, leading to a larger focus spot and blurred images. Chromatic aberration and transmittance will deteriorate if used outside the specified wavelength range. When used with a high-power laser or near a light source that produces heat, the focal length has possibility to change due to the high temperature of the lens. Heat dissipation measures are required for prolonged irradiation. If the incident beam diameter is too small, the spot size will not be well focused. Chromatic aberration is not corrected in this focusing lens, which is not an achromatic lens.
