| Guide | ▶Dedicated Fixed Framed Lens Holder (LHF-M29-25, LHF-M34-30) are available for fixing various Focusing Lenses. ▶HFTLSQ-15-20PF comes with a dedicated adapter for mounting on Fixed Framed Lens Holder (LHF-M29-25). ▶HFTLSQ-20-30PF comes with a dedicated adapter for mounting on Fixed Framed Lens Holder (LHF-M34-30). ▶Custom-made Focusing Lenses for high-energy pulsed lasers and for specified wavelengths are also available. ▶Production in lots exceeding 100 pieces to customer specifications is also available. ▶To protect the lens from laser-processed splashes, optional Protective Glass (PG-33) can be attached. |
| 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. |
