The LCD Plan Apo NIR HR 100X (t0.7) is a high-performance plan apochromat objective designed for bright field inspection and laser-based repair applications through 0.7 mm LCD cover glass (BK-7). Engineered for advanced imaging tasks, it provides wavelength correction from the visible spectrum up to near-infrared (480–1800 nm), making it ideal for NIR inspection and laser processing environments.
As a High Resolution (HR) model, this objective delivers exceptional resolving performance with a high numerical aperture of 0.7 and a resolving power of 0.4 µm. Its dedicated LCD glass thickness compensation ensures optimal image quality when imaging through specified substrate materials.
With a working distance of 10.11 mm through 0.7 mm glass, the lens maintains practical clearance while providing sharp, high-contrast imaging. The infinity-corrected plan apochromat design ensures flat-field performance and excellent chromatic correction across the extended visible-to-NIR wavelength range.
