Sigma optical fiber laser focusing lens

Product Introduction:

For lenses with a focal length of over 60nm, the spherical aberration and coma at a wavelength of 1064nm are fully corrected, and the focal spot diameter after collimated laser imaging is almost close to the diffraction limit.
Coated with a broadband anti reflection film, it can be used for fiber coupled lasers in the wavelength range of 1040-1150nm.
There is also a certain transmittance at 632.8nm, and He Ne laser can be used as a light guide.

▶ Equipped with dedicated brackets for fixed condenser lenses (LHF-M29-25, LHF-M34-30, LHF-M50.9-50).

▶ HFTLSQ-15-20PF1 comes with a dedicated adapter required for installation onto the condenser lens bracket (LHF-M29-25).
▶ The HFTLSQ-20-30PF1 comes with a specialized adapter required for installation onto the condenser lens bracket (LHF-M34-30).
▶ Undertake the manufacturing of high-energy pulse lasers or products with specified wavelengths outside of the product catalog.
▶ According to customer technical specifications, hundreds of orders of magnitude can be produced in bulk.
▶ In order to protect the lens from damage caused by powder splashing during laser processing, additional protective window glass can be configured for sale.

▶ A spotlight lens enables an infinitely distant object to be imaged at the focal position, or converts a point light source into parallel light. If we want to image objects at close range, the optical performance of the lens will not be fully utilized.
▶ The incident light must enter the condenser lens from the specified direction, and the parallel light must be incident into the lens from above (engraved with upright text). If the incident light enters the lens from the opposite direction, it will cause the spherical aberration to deteriorate, the focal spot to become larger, and the image to become blurry.
▶ When used under conditions outside the designed wavelength, it leads to deterioration of spherical aberration and a decrease in transmittance.
▶ When using high-power lasers or near heat sources, it may cause an increase in the temperature of the condenser lens and a change in focal length. If used for a long time, good heat dissipation measures must be taken.
▶ If the diameter of the incident beam is too small, a small spot cannot be obtained.
▶ This spotlight lens is not an achromatic lens and does not correct chromatic aberration.
