Infinite Plan Semi-Apo Fluorescent Objective for Upright Microscope

10X NIR Infinity Long Working Distance Metallrugical Industrial Objective Lens NIR, NUV, and UV Infinity Corrected ObjectivesIdeal for Bright Field Imaging in UV, Visible, and NIR Spectral RegionsExcellent Performance at Nd:YAG Laser LinesBroad Spectral Ranges20x M Plan APO NIR Objective This objective is suitable for laser applications and provides long working distances between the lens and working surface. NIR, NUV, and UV infinity corrected long working distance objectives combine the benefits of the standard M Plan Apo and M Plan Apo series objectives with enhanced spectral ranges. The NIR objectives are corrected from 480 to 1800nm, making them ideal for semiconductor and telecommunication inspection, or for laser cutting with common Nd:YAG lasers. The HR series offers an increased numerical aperture, providing smaller spot sizes and higher resolution. The NUV and UV series of objectives have excellent performance at the doubled, tripled, and quadrupled.     ItemNAWD(mm)f(mm)R(μm)DF(μm)On object(mm)WF 10X24On image(mm)1/2 CCDWavelength5X0.1545402.5184.80.96X1.28400-1064nm10X0.334201.03.502.40.48X0.6420X0.331101.03.501.20.24X0.3220X0.4520.2100.71.71.20.24X0.3250X0.4520.1640.71.60.450.1X0.1350X0.659.640.40.550.480.1X0.13This objective is suitable for laser applications and provides long working distances between the lens and working surface.With 10 years of exporting experience, FSM provides 24 hours service for our distributors.
