The 1.1mm glass thickness is found in older LCD panel generations, certain semiconductor packaging substrates, and other flat panel or encapsulated specimen configurations. Selecting the correct t-value is critical: using a t0.7-corrected objective on a 1.1mm substrate (or vice versa) will introduce residual spherical aberration that degrades resolution and contrast at 50×. The t1.1 correction ensures optimal optical performance specifically for this substrate thickness. The 480–1800nm spectral range enables NIR and SWIR imaging through the 1.1mm glass layer, including inspection at NIR wavelengths where panel defects, electrode structures, and backplane features are more clearly revealed than in visible light, as well as InGaAs camera imaging and Raman spectroscopy with NIR\/SWIR excitation lasers. The 17mm working distance provides practical clearance for large panel specimens and inspection fixtures. For 0.7mm glass substrates at 50×, see the LCD Plan Apo NIR 50× t0.7 (378-829-16). For uncovered specimens at 50× NIR\/SWIR, see the M Plan Apo NIR 50× series (378-825-17 or 378-863-5 HR). Compatible with Mitutoyo FS series microscopes and other infinity-corrected systems with M26 thread nosepieces.
