Representing the mid-sized option in their line of modular spotting scopes, the Swarovski Optik ATX/STX/BTX 95mm Objective Lens Module gets an updated tripod shoe that fits Arca-type quick release plates and accepts any of the three available eyepiece modules including straight viewing (STX), angled viewing (ATX), or the binocular viewer (BTX). The bayonet mount for the eyepiece modules is backward compatible with the original ATX/STX modules, so it's easy to upgrade your objectives without needing a new eyepiece module. The 95mm objective strikes a nice balance between light-gathering ability and portability, making it well suited for hunters, outdoor enthusiasts, and birders. Extra-low dispersion fluoride glass elements efficiently transmit all wavelengths of visible light, resulting in bright images that are color faithful, crisp, and rich with detail. An integrated field-flattener lens system corrects spherical aberrations to reveal crisp details at the edges of the view without distortion. SWARODUR and SWAROTOP coatings on all lenses and prisms minimize glare while maximizing contrast.
Complementing the optical performance is a lightweight and durable magnesium-alloy chassis that is wrapped in a protective rubber armor. Its optical tubes are nitrogen filled and O-ring sealed to be dustproof, waterproof, submersible, and resistant to internal fogging when moving through extreme temperature changes or environmental conditions. The tripod collar has a 1/4"-20 socket on the bottom of the Arca-type compatible shoe and rotates to allow for precise eyepiece placement relative to the mounting system.
- Separate eyepiece module required: straight (STX) or angled (ATX) viewing and binocular viewer (BTX) available
- Large 95mm objective lens draws in more light than the smaller module and produces a larger exit pupil for improved low-light performance
- Extra-low dispersion fluoride HD glass limits chromatic aberrations to produce clearer and sharper views with little or no color fringing
- Field-flattener lens system eliminates spherical aberrations to eliminate distortion at the edges of the field of view
- Antireflection SWAROTOP lens coatings reduce glare and improve contrast, color rendition, and clarity
- Scratch-resistant SWARODUR coatings protect exterior lens surfaces
- Large focusing collar is easy to manipulate even when wearing gloves
- Rotating tripod mount allows for precise eyepiece placement
- M97x0.75 objective lens filter thread
- Tripod shoe is compatible with Arca-type quick release plates; standard 1/4"-20 socket on bottom of shoe
- Lightweight and impact-resistant magnesium-alloy housing
- Rubber armor protects against impacts and provides a slip-resistant grip for more secure handling during setup and breakdown
- SWAROCLEAN nonstick coating on exposed lens surfaces allows sap and oils to be easily cleaned for clearer views
- Nitrogen filled and O-ring sealed to be dustproof, waterproof, submersible to 13', and resistant to internal fogging when moving through extreme temperature changes or environmental conditions
- Broad -13 to 131°F operating temperature range
