About Explore Scientific 100 Degree 5.5mm Argon-Purged Waterproof Eyepiece, 2" Barrel

Are you seeking an unparalleled viewing experience for your astronomical or microscopic observations Look no further than the Explore Scientific 100 Degree Series 5.5mm Argon-Purged Waterproof Eyepiece. Engineered with precision and the astute observer in mind, this high-quality eyepiece is the epitome of optical excellence, designed to deliver high contrast, high resolution, and a superior flat field across an expansive 100-degree apparent field of view.

Crafted using a sophisticated combination of low dispersion and high refractive index optical glasses, this durable eyepiece is enhanced with multilayer deposition coatings. These advanced coatings are meticulously applied to ensure maximum light transmission, resulting in images that are bright, clear, and full of detail. The fully multi-coated lenses are a testament to the eyepiece's ability to reduce internal reflections and elevate the clarity of your observations.

The robust construction of this eyepiece makes it an ideal companion for the outdoor enthusiast. Waterproof and ruggedized, it is built to endure the elements, ensuring reliable performance in wet or humid conditions. The argon-purged design not only prevents internal fogging but also protects against the intrusion of fine particulates and potential fungal damage, thereby preserving the integrity of the internal coatings over time.

Experience the extreme full-immersion effect provided by the long eye-relief and wide-angle view. The visual impact is nothing short of breathtaking, offering an immersive experience that must be seen to be believed. Each lens element within this eyepiece is carefully cleaned and aligned within its precision-machined barrel, ensuring optimal performance.

The attention to detail extends to the Enhanced Multilayer Deposition (EMD) Coatings on each lens and lens grouping. These coatings, along with edge-blackened optics, effectively eliminate light scatter and maintain image contrast. Strategic baffles further enhance contrast by masking and deflecting stray light that could otherwise detract from the viewing experience.

To guarantee its waterproof integrity, each eyepiece undergoes rigorous testing, including submersion to a depth of 1 meter for 30 minutes. This level of quality assurance means that you can trust the Explore Scientific 100 Degree Series 5.5mm Eyepiece to deliver exceptional performance, even in the most challenging environments.

Elevate your observation experience with this wide-angle, argon-purged, and fully multi-coated eyepiece, designed for those who demand nothing but the best in their optical equipment.
