Olympus ULWD NeoSPlan 20x / 0.40 Ultra-Long Working Distance Microscope Objective | IC 20 Strain-Free

Up for sale is a professional-grade Olympus ULWD NeoSPlan 20x industrial metallurgical microscope objective (Serial No. 104311), precision-crafted in Japan. This infinity-corrected (\infty/0, f=180) lens is designed for specialized inspection applications, including semiconductor quality control, wafer probing, and materials science.

Key Features:

• Ultra-Long Working Distance (ULWD): Features a massive 11.0mm working distance, providing substantial physical clearance to inspect deep recesses or utilize micro-probes without risking damage to the specimen or lens optics.

• IC 20 Stamping (Strain-Free): Features the rare, sought-after "IC" designation (marked by the green band), meaning the internal glass elements are meticulously selected and engineered to be strain-free. This makes the objective fully compatible with Polarized light and Nomarski Differential Interference Contrast (DIC) microscopy.

• Dual-Channel Neo Barrel: Built with a wide-diameter dual-channel design allowing for seamless use in both Brightfield (BF) and Darkfield (DF) viewing modes.

Specifications:

• Magnification: 20x

• Numerical Aperture (NA): 0.40

• Tube Length Focal Standard: Infinity Corrected (\infty / 0, f=180)

• Working Distance: 11.0mm

• Mounting Thread: Olympus Neo Thread

Condition:

The objective is in excellent physical and cosmetic condition. The silver chrome barrel is exceptionally clean with bold, perfectly legible text engravings. As shown in the detailed photographs, the front lens element and rear glass are crisp, bright, and completely free of scratches, wipe marks, hazing, or internal delamination. Threads are clean and intact.
