The objective lens, located at the front of the riflescope, gathers light and determines the scope’s light-gathering capability. A larger diameter objective lens generally allows for better performance in low-light conditions. Its size directly impacts exit pupil diameter, a crucial factor for a clear sight picture. Bushnell offers a variety of objective lens sizes across its product line, catering to different lighting conditions and magnification ranges.
-
Erector Lens System
The erector lens system, situated within the scope’s body, magnifies the image formed by the objective lens. This system contributes significantly to the overall length and weight of the scope. The quality of these lenses affects image sharpness and brightness. Bushnell utilizes various erector lens designs and coatings to maximize light transmission and minimize chromatic aberration across its diverse range of riflescopes.
-
Ocular Lens
The ocular lens, located at the rear of the riflescope, is what the shooter looks through. It magnifies the image produced by the erector lens system and presents the final image to the eye. Eye relief, the distance between the ocular lens and the shooter’s eye, is a critical factor for comfort and safety, particularly with high-caliber firearms. Bushnell designs its ocular lenses with specific eye relief considerations for various shooting applications.
-
Lens Coatings
Lens coatings play a vital role in light transmission and image quality. Anti-reflective coatings minimize glare and maximize light passing through the lens system, improving brightness and clarity, particularly in challenging light conditions. Bushnell employs proprietary lens coatings, such as Rainguard HD and EXO Barrier, to enhance performance in various environments and protect against scratches and other damage.
Careful consideration of these lens characteristics is essential for maximizing riflescope performance.

Reticle Focus
The reticle focus mechanism adjusts the sharpness of the reticle, ensuring a clear and defined aiming point. This adjustment, usually located on the eyepiece, compensates for individual eyesight variations, allowing for optimal clarity. A crisp reticle is essential for precise shot placement, especially at higher magnifications. Bushnell utilizes different reticle focus mechanisms across its product range, each designed for specific applications and performance levels.
-
Parallax Correction
Parallax occurs when the reticle and target image are not on the same focal plane, leading to aiming errors as the shooter’s eye moves behind the scope. Parallax correction mechanisms, typically located on the objective lens or side focus turret, adjust the focal plane to align with the target, eliminating parallax error and ensuring accurate shot placement, especially at longer ranges. Bushnell incorporates various parallax adjustment systems in its scopes, catering to different shooting disciplines and distances.
-
Illumination System (If applicable)
Illuminated reticles enhance visibility in low-light conditions. The illumination system, often integrated within the internal mechanisms, controls the brightness and sometimes the color of the reticle. This feature improves target acquisition in challenging lighting, benefiting hunters and tactical shooters. Bushnell offers various illuminated reticle options with different brightness settings and colors to suit diverse environments and preferences. This system typically requires a battery and adds complexity to the internal workings of the scope.
