Infinity plan high contrast objective
The Infinity Plan High Contrast Objective is engineered for researchers and industrial users who demand superior optical performance. Crafted with a precision brass barrel and high-grade glass elements, it delivers exceptional image flatness, contrast, and color fidelity, significantly outperforming standard achromatic objectives. Its standardized RMS thread (W20.32X0.706) and 45mm parfocal distance ensure seamless integration into infinity-corrected microscope systems with a 180mm tube lens.
This objective leverages an infinity-corrected optical design, where light exits as a parallel beam. This key advantage allows you to introduce filters, polarizers, or beam splitters into the optical path between the objective and the tube lens without introducing spherical aberration or affecting focus. This makes the Infinity Plan High Contrast Objective https://www.phenixoptical.com/microscope/medical-microscope/professional-biological-microscope.htmlexceptionally versatile, ideal for advanced techniques such as transmitted light contrast, reflected light fluorescence, and high-resolution imaging in both research and quality control applications.
Manufactured under strict ISO 9001 quality standards and backed by 60 years of optical expertise, this objective undergoes rigorous inspection to guarantee performance and durability. We provide a one-year warranty and full technical support. For laboratories requiring reliable, high-end imaging components, this objective represents a cost-effective solution that combines advanced optical correction with robust, dependable construction.
