Mitutoyo 378-893-8 LCD Plan UV 50X(t0.7) Objective for bright-field observation in ultraviolet range with cover glass compensation

The LCD Plan UV 50X (t0.7) is a precision objective lens designed for bright field inspection and laser applications through 0.7 mm LCD (SiO₂) cover glass. Engineered with a high-quality plan optical design, this objective is specifically corrected for both ultraviolet (266 nm) and visible (550 nm) wavelengths, making it ideal for advanced inspection and UV-based applications.

With a long working distance of 12.6 mm through 0.7 mm glass, the lens enables stable and accurate imaging while maintaining excellent clearance. Its infinity-corrected design and dedicated glass thickness compensation ensure optimal performance when imaging through LCD substrates or similar materials.

Compatible with VMU / FS-70 microscope systems, the LCD Plan UV 50X is well suited for precision inspection, laser processing observation, and UV-sensitive applications.
