PAL - PAL-L
The PAL series visible objectives offer diffraction-limited performance across the visible spectrum. These objectives minimize aberrations and maximize transmission by utilizing multi-element optics with optimized coatings and infinity-corrected design. Key technical specifications include: High Numerical Aperture (NA): Enabling high-resolution imaging and fine detail capture. Achromatic Correction: Minimizing chromatic aberration for accurate color reproduction. Long Working Distance Options: Facilitating integration into complex setups. Standard RMS Threading: Ensuring compatibility with typical microscope and optical mounts. Applications span microscopy, machine vision, and precise optical inspection, where demanding resolution and image quality are paramount.
