Dragon Skin A/R coating is an advanced broadband multi-layer oleophobic anti-reflective coating. It is applied in a vacuum chamber using high voltage electron beam ionization to evaporate a series of different materials. The thickness of each layer is controlled by a state-of-the-art software system using a quartz crystal as an in-chamber-measuring device.

Oleophobic means oil-repellent. Our Oleophobic Dragon Skin coating repels dust, oil (finger prints), and dirt.

Dragon Skin coating was engineered with a thermally cured, hard lacquer anti-scratch surface designed specifically for lenses. This extremely hard quartz based layer sets Dragon Skin apart from all other coatings with its incredible scratch resistance. Subsequent layers of aluminum and titanium are deposited to eliminate reflections. Finally, an oleophobic topcoat is applied to protect the coating and aid in ease of cleaning. An ion source is used during the deposition process to ensure flawless coatings. Only state-of-the-art equipment is capable of applying this coating due to extremely tight tolerances.

The residual color of this coating is a light greenish tint. There are two reasons for this color. First, green is the most neutral color of the spectrum, and therefore is the least obvious to the shooter. Second, the A/R coating has the best performance in the green spectrum enabling higher light transmission rates.

True Spot lenses work best for shooting spot targets.  In the beginning Jim did grind True Spot lenses with spot sizes as large as one inch. In large scopes this gave a wide field of view with the equivalent of a 1" scope floating in the middle of the lens.

Clarifiers will bring images past 20 feet in focus if the correct combination of power and distance is used. See chart on Clarifier Power page.

Clarifiers make close images difficult to see ( pins, dots, etc.). The higher the power clarifier the more difficult it is to see close. 

Yes, if you prefer a center dot you will find a True Spot lens is much easier to use than a
standard 4x, 6x, or 8x lens.  I would recommend a 3/8" spot, since the power in the center is the same as a standard lens the True Spot will give a large relaxed field of view.
True Spot Lenses are Optical Glass ground to exceptional quality with Zeiss Gold Coating.

Yes, since True Spot Lenses eliminates the need for a pin or dot, a clarifier can bring the
the magnified X in focus. This is a personal preference as many people shoot True Spot
without clarifiers,

Our new center drilled AIR-O lens will fill this gap. We are also in the process of designing a pin system for our housings.
