The LCD Plan Apo NUV 50X (t0.7) is a high-quality plan apochromat objective designed for bright field inspection and laser applications through 0.7 mm or 1.1 mm LCD cover glass (BK-7). Engineered for precision imaging, it provides wavelength correction from the visible spectrum down to near-ultraviolet (355 nm), making it ideal for advanced inspection and near-UV laser processing applications.
With a long working distance of 15 mm through 0.7 mm glass, this objective offers 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.
The lens includes dedicated LCD glass thickness compensation, ensuring optimal image quality when observing through specified substrate materials. A High Resolution (HR) variant 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 50X is well suited for precision inspection, laser processing observation, and demanding near-UV applications.
