Long working distance objective lens (45mm focal length)

Product Introduction

Correct color difference within the visible spectral range (400-700nm).
EPL/EPLEobjective lensLightweight structure, used for autofocus and other purposes, can improve the response speed of the objective lens driving mechanism (SFS-OBL/SFAI-OBL).

▶ Equipped with a fixed objective lens holder (LHO-26).

▶ If you need to fix the objective lens on the cross motion bracket, please consult the sales department.
▶ When used as a laser processing objective lens, our company also supplies coaxial illumination observation units (OUCI-2) and laser introduction color separation prisms (DIMC)

▶ When using the objective lens for laser processing, please adjust the diameter of the incident beam (1/e)²）Used when expanding to about half the pupil diameter. When the incident beam is too thin, a very small focused spot cannot be obtained, and the energy density of the laser will increase, which may also damage the objective lens.
▶ When using an objective lens for laser processing, the powder splashed during processing may contaminate the mirror surface of the objective lens. Please ensure sufficient working distance (WD) or insert thin protective lenses to avoid dirtying the objective lens.
▶ The magnification is the value when using an imaging mirror with f=200mm. When using imaging mirrors from other manufacturers, the magnification may be different. Firstly, it is necessary to confirm the focal length of the imaging lens used, and calculate the actual magnification based on the ratio of the focal length of the imaging lens to the focal length of the objective lens.
