The LCD Plan Apo NUV HR 50X (t0.7) is a premium plan apochromat objective designed for bright field inspection and laser applications through 0.7 mm LCD cover glass (BK-7). Engineered for high-precision imaging, it offers wavelength correction from the visible spectrum down to near-ultraviolet (355 nm), making it ideal for advanced inspection and near-UV laser applications.
As a High Resolution (HR) model, this objective delivers enhanced resolving performance with a resolving power of 0.4 µm, supported by a high numerical aperture of 0.65. Its dedicated LCD glass thickness correction ensures optimal image quality when observing through specified substrate materials.
With a working distance of 10 mm through 0.7 mm glass, the lens provides practical clearance while maintaining exceptional optical clarity. The infinity-corrected plan apochromat design ensures flat-field imaging and excellent chromatic correction across the extended wavelength range.
Compatible with VMU and FS-70 microscope systems, the LCD Plan Apo NUV HR 50X is ideally suited for precision inspection, laser processing observation, and demanding near-UV applications.
