DX.7900-T Infinity‑corrected 100× / 1.25 Plan Semi‑Apochromatic Objective (Objective lens)

DX.7900-T is an infinity‑corrected, plan semi‑apochromatic objective designed for high‑resolution light microscopy with M25 mounting and cover‑glass correction.

• High NA 1.25 for superior resolution
• 100× magnification for fine detail
• M25 thread for compact mounting

Exceptional resolving power for detailed imaging

The objective delivers a marked improvement in detail reproduction thanks to its numerical aperture of 1.25, which defines the light‑gathering ability and resolving power. A higher NA translates directly into finer detail and improved contrast at high magnifications; this makes the lens particularly suitable where precise structural discrimination is required. The plan semi‑apochromatic correction reduces field curvature and compensates for chromatic aberration across the visible spectrum, so images remain sharp from centre to edge.

Compact design and straightforward integration

With an M25 thread and a compact form factor, the lens integrates easily into systems that accept small‑format objectives. The specified working distance of 0.2 mm supports very close focal approaches for high‑magnification observation while the infinity‑corrected optical design enables compatibility with a wide range of modern microscope tubes and intermediate optics. These mechanical and optical attributes streamline retrofits and reduce alignment time in busy laboratories.

Practical optical features explained

The optical designation indicates an infinity‑corrected system and cover‑glass correction, meaning the objective is engineered to perform when the specimen is observed through a standard cover glass and when used with a tube lens in an infinity optical path. Cover‑glass correction compensates for the refractive effect of the glass, preserving image quality; users should match cover‑glass thickness and the chosen imaging medium to obtain optimal results. Such design choices reduce the need for downstream image corrections and increase throughput.

Applications and benefits for precision microscopy

This objective is aimed at demanding tasks that require reliable high magnification and consistent field flatness, such as detailed material inspection, histological observation, or any application needing critical visual assessment under a light microscope. The 100× magnification paired with the high NA supports the visualisation of fine structures, while the compact M25 mount helps laboratories maintain a small, flexible optical footprint. The lens thus contributes to reproducible results and faster sample evaluation in routine and specialised workflows.
