Microscope objective iScope IS.7200 — 100x, NA 1.25 oil-immersion by Euromex

The Microscope objective iScope IS.7200 is an oil-immersion lens engineered for high-resolution imaging in life science and educational microscopy, offering tight focal control and contrast at high magnifications

• 100x oil-immersion magnification
• Numerical aperture 1.25 for high resolution
• Working distance 0.13 mm for fine focus proximity
• Designed for life science and education microscopy

Outstanding resolution for high-detail imaging

The combination of 100x magnification and a numerical aperture of 1.25 delivers substantially improved resolving power compared with lower-NA objectives; this means finer structural details become distinguishable in brightfield and high-contrast techniques. The high NA increases the objective’s light-gathering capability, so images show better contrast and sharper edges under the same illumination. As an oil-immersion design, the lens is intended to be used with immersion oil at the specimen–coverslip interface, which bridges refractive-index differences and directly improves optical performance for critical observations.

Practical integration into laboratory workflows

Engineered for routine use in teaching labs and research benches, this objective couples high resolution with compact handling and simple mounting on standard nosepieces. The short working distance (0.13 mm) places the focal plane very close to the coverslip; this gives maximum detail for thin sections and cell preparations but necessitates careful focusing and oil application. The construction and optical design support reproducible imaging across sessions, which helps laboratories maintain consistent results and reduces time spent on re-optimising imaging parameters between users.

Safe handling, maintenance and application notes

A short working distance requires deliberate handling: apply immersion oil sparingly, avoid contacting the lens with hard objects, and focus with coarse adjustments retracted to prevent collisions. After use, clean immersion oil promptly with appropriate lens tissue and a suitable solvent to protect the optical surfaces. For users unfamiliar with oil objectives, the benefits include noticeably higher resolution at high magnifications and improved numerical-aperture performance; if uncertainty exists about compatibility with a particular microscope or intended application, technical advice is available by email or phone to clarify integration and correct usage.

FAQ

What immersion medium is required for optimal performance?
The Euromex iScope IS.7200 is specified as an oil-immersion objective; use optical immersion oil between the coverslip and the objective to achieve the stated numerical aperture of 1.25 and the highest resolution.

Is this objective compatible with standard research microscopes?
Compatibility depends on the microscope’s nosepiece and optical tube length; the iScope IS.7200 will fit most standard revolving nosepieces used in life-science microscopes, but confirm mechanical fit and parfocality before installation.

How does a numerical aperture of 1.25 affect imaging?
A numerical aperture of 1.25 increases light collection and resolving power, providing finer detail and improved contrast at high magnification compared with lower-NA lenses; this makes fine structural features more discernible.

How close can the objective approach the specimen, and what precautions are needed?
With a working distance of 0.13 mm, the front lens sits very near the coverslip; users should apply oil carefully and focus slowly to avoid contact with the specimen or cover glass.

What cleaning routine is recommended after use with immersion oil?
Remove excess oil promptly using lens tissue and an appropriate cleaning solvent; follow the microscope and objective manufacturer’s instructions to preserve coatings and optical alignment.
