The LCD Plan Apo NUV 20X (t0.7) is a precision plan apochromat objective designed for bright field inspection and laser applications through 0.7 mm or 1.1 mm LCD cover glass (BK-7). With wavelength correction from the visible spectrum down to near-ultraviolet (355 nm), it is ideally suited for advanced inspection and near-UV laser processing applications.
Featuring a long working distance of 17.2 mm through 0.7 mm glass, this objective provides excellent clearance while maintaining strong optical performance. Its infinity-corrected plan apochromat design ensures flat-field imaging and superior chromatic correction across the extended wavelength range.
Dedicated LCD glass thickness compensation ensures optimal image quality when observing through specified substrate materials. A High Resolution (HR) version is also available (LCD Plan Apo NUV HR) for applications requiring enhanced resolving performance.
Compatible with VMU and FS-70 microscope systems, the LCD Plan Apo NUV 20X is well suited for precision inspection, laser process monitoring, and demanding near-UV applications.
