The BS-5040 series of transmitted polarizing microscopes are designed for high-precision observation of a wide range of polarized specimens, including mineral thin sections, polymers, crystals, and particulates. These microscopes feature a smooth, rotating, and graduated stage combined with a set of polarizers that enhance clarity and detail in transmitted light applications. The instrument is equipped with an advanced color-corrected infinity optical system, ensuring superior image quality and resolution. It also includes strain-free infinity plan objectives, offering a magnification range from 40X to 400X. A digital camera can be paired with the BS-5040T model for image capture and analysis.
Key features include:
1. **Color-Corrected Infinity Optical System** – Ensures accurate color reproduction and sharp imaging across various magnifications.
2. **Strain-Free Infinity Plan Objectives** – Provide excellent resolution and clarity, ideal for detailed microscopic studies.
3. **Center-Adjustable Components** – The nosepiece and rotating stage allow for precise alignment, improving operational accuracy and reliability.
The BS-5040 series is widely used in geological research, mineralogy, metallurgy, university laboratories, and industrial sectors such as chemical fiber production, semiconductor manufacturing, and pharmaceutical inspection. Its versatility makes it a valuable tool in both academic and professional settings.
