Index Matched Lens System
A Leupold exclusive, this system has nearly perfected Leupold's already impeccable light management. Leupold engineers specify different coating materials for each lens surface in the riflescope, based on the lens' index of refraction, placement and function, layering each coating to eliminate reflections and maximize light transmission. The result is unparalleled brightness and extremely sharp resolution across the entire visual field.

What is Twilight Factor?
The factor that has the greatest impact on resolution or image detail, will be dependent upon the amount of light available during the time of observation. During daylight hours, when your eye pupil size will be only about 2 to 3mm, magnification will be the principal factor in image resolution. At night, with the eye pupil dilated to 6 to 8mm, aperture size is the controlling factor. In twilight conditions both of these factors control resolution effectiveness and the twilight factor is the term that compares binocular performance under these conditions.

The twilight factor is calculated by taking the square root of the product of the magnification and the aperture. The higher the twilight factor, the better the resolution of the binocular when observing under dim light conditions. For example, a 10 X 40 (twilight factor 20) would effectively resolve better under these conditions than a 7 X 35 (twilight factor 15.4) even though the 10 X 40 has a smaller exit pupil. Remember, however, that the twilight factor does not take into account the transmittance or quality of the optical system.

The Leupold Golden Ring 12-40x60mm HD spotting scope offers impeccable optical performance with unmatched resolution and brightness, even at the highest magnification. The compact tripod features adjustable legs and a swivel/tilt head. The Leupold digital camera adapter makes digiscoping easy. Compatible with most digital cameras. Window mount makes in-vehicle use simple. The hard-side case is rugged and features a padded interior to protect your valuable Leupold optics
