Kowa TSN-99A KIT (SKU: 12264 TSN-99A KIT)

The Kowa TSN-99A Prominar 30 - 70x telescope, paired with the TE-11WZ II wide-angle eyepiece, is a professional-grade set designed to meet the needs of the most discerning users. Crafted using the finest materials available, this product boasts unparalleled image quality and exceptional durability.

This spotting scope utilizes an advanced optical system constructed with premium fluorite and low-dispersion Kowa XD ™ glass. Fluorite, found naturally near hydrothermal veins and in igneous rocks, possesses an incredibly low refraction index (n = 1.4), surpassing even the highest quality optical glass. This unique property of fluorite allows lenses made from it to minimize chromatic aberration, resulting in impeccable color reproduction and outstanding contrast. The Kowa TSN-99A Prominar telescope employs synthetic fluorite, devoid of rare earth impurities that cause a greenish or purple tint. However, it is worth noting that fluorite presents challenges in processing due to its propensity for chipping. Over the years, Kowa has developed a proprietary technology for grinding and polishing lenses made from this material, resulting in unrivaled image quality in optical instruments.

To further enhance image quality, fluorite lenses are coated with a comprehensive multi-layer anti-reflective coating, delivering sharp and clear visuals even in challenging lighting conditions. The entire structure is enclosed in a sealed and nitrogen-filled housing, ensuring the equipment remains impervious to adverse weather conditions such as rain, snow, or low temperatures.
