Bresser EXPLORE SCIENTIFIC 68 Ar Eyepiece 16mm (1.25 inch)

Improvements in Eyepiece Manufacture

• 15-layer Enhanced Multi-layer Deposition (EMD) coatings on all glass-to-air surfaces to maximize contrast.
• Waterproofing achieved by Argon gas purging instead of standard Nitrogen gas, providing superior protection over a wider temperature range and enhanced resistance to diffusion, extending the eyepiece's protective environment.

Design and Optical Performance

• Computer-optimized design combined with careful selection of optical glasses and enhanced multi-layer coatings.
• Features long eye relief for comfortable viewing.
• Delivers high image correction and a flat field for sharpness across the entire field.
• Provides high contrast throughout the 68° apparent field of view.
• Ideal for extended visual studies of subtle brightness variations and suitable for eyeglass wearers.

Coating and Contrast

• All 68 Series eyepieces are fully EMD-coated and edge-blackened to enhance contrast and reduce stray light.
