Nikon Introduces New MONARCH Fieldscopes
August 19, 2013
Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to announce the release of its new MONARCH Fieldscopes which employ the Hybrid Body System.
The optical system of Fieldscopes designed for observation has been used for digiscoping up to now. The new MONARCH Fieldscopes break fresh ground with an optical system that achieves both observation and detailed digiscoping. This is made possible through the Hybrid Body System. With the completely redesigned optical system and body structure, the user can freely choose the preferred combination of objective lens unit, prism unit (straight or angled) and eyepiece. Even more impressive is the realisation of higher-definition prime focus shooting through the direct connection, without going through the prism unit, of the desired attachment to the Fieldscope body.
The new MONARCH Fieldscopes are true heirs to the widely acclaimed "MONARCH" brand which has gained tremendous popularity among birdwatchers and nature observation lovers. As a brand that consistently delivers highly reliable performance, Nikon remains committed to the further expansion of its attractive MONARCH lineup that meets the needs of various users around the world.
MONARCH Fieldscope Key Features
- Hybrid Body System realises an optimised optical system for both observing and digiscoping;
employs a unit structure that permits the prism unit to be easily attached/detached from the objective lens unit;
enables your desired combination of Fieldscope diameter, prism and eyepiece for observation, as well as realising prime focus digiscoping via attachment - One focus ring for quick and fine-focusing performance: Dual Trans Focus System
- Advanced apochromat optical system uses ED (Extra-low Dispersion) glass, realising a contrast-rich, clearer field of view
- Field-flattener lens system employed for consistent sharpness across the entire field of view
- Multilayer coating is applied to all lens and prism surfaces, ensuring superior brightness and colour fidelity
- Highly reliable sleeve mechanism enables connection of an objective lens unit and prism unit to minimise optical axis deviation
- Employing a prism featuring total reflection minimises light loss and provides a bright, clear field of view
- Fully rubber-armoured exterior body fits comfortably in your hand; easy-to-operate focus ring
- Labyrinth structure prevents water entering and each unit is filled with nitrogen gas for waterproof performance
- Objective lens unit/Prism unit: Waterproof (up to 1m for 10 min.) *1 and fog-free with nitrogen gas
Unit joint: Waterproof (water equivalent to 5mm per minute for a duration of 30 minutes) *2
Eyepiece: Not waterproof. Waterproof when attached to the Fieldscope body. *2
- *1This product will suffer no damage to the optical system if submerged or dropped in water to a maximum depth of 1 metre for up to 10 minutes. NOT designed for underwater usage.
- *2This product will suffer no damage to the optical system in falling water equivalent to 5mm rainfall per minute for a duration of 30 minutes. NOT designed for underwater usage.
Fieldscope Eyepiece Key Features
- Advanced optical system provides a wide field of view and comfortable eye relief
- Refined optical design corrects chromatic aberrations effectively and delivers a uniformly sharp image throughout the field of view
- CircuLock system is employed so that an eyepiece can be easily and smoothly attached/detached, with the eyepiece mounting firmly secured
- Multilayer coating is applied to surfaces of all lens elements
- Connecting joint is sealed with waterproof packing to ensure waterproof performance when attached to a Fieldscope
