A past master in the art of lenses, Julbo continues to lead the field with
cutting-edge solutions perfectly adapted to the requirements of high-level
sport. Our technical lenses Falcon, Octopus, Cameleon, Zebra and Zebra
Light continue to use NXT Technology for unrivalled performance and the
most effective solution for each discipline and each user.

4. 2. NXT TECHNOLOGY// a lens for all occasion
The technology was initially developed for the US Army in the 1990s for two
purposes:
 To protect against bullets
 To guarantee the finest optical quality
NXT is used in the most extreme conditions:
Aeronautics:
helicopter windscreens
Motor sports:
helmet visors
Police forces:
riot shields

5. 2 // NXT, a high-tech lens
NXT is made from Trivex, the most effective material on the optics market,
combining the advantages of mineral and organic materials.
 An optical quality close to that of mineral glass
 Crystal clear images
 Stronger than polycarbonate
 The lightest
2 // A unique manufacturing process
NXT is produced by casting at moderate temperature rather than by
injection molding.

7. 2 // With NXT, get the competitive advantage
NXT lens characteristic:
Lightweight
With a density of 1.11, the NXT lens is the lightest lens currently available.
Superior optical quality
NXT is cast at moderate temperature: no residual internal stress.
The geometry of the lenses is homogenous: no image distortion.
Unbreakable
An NXT lens can withstand the impact of a 7mm bullet travelling at 165 kph.

8. 2 // Get the competitive advantage
NXT lens characteristic:
Crystal clear image:
the ABBE number of the NXT lens is 45.
Its chromatic aberration is 1.5 times lower than polycarbonate.
Vision is clearer.
Resistance
 Mechanical strength : NXT lenses withstand repeated stresses.
NXT lenses have withstood torsion tests applied for 10,000 cycles.
 Resistance to solvents : NXT withstands the effects of acetone.
An NXT lens subjected to petrol vapours for 10 minutes remains
intact.
 High scratch and cracking Resistance
Longlasting material treatment: NXT lenses undergo an
in-mass photochromic process. The polarizing films of NXT
lenses are inserted into the centre of the lens between two
layers and are therefore protected against any risk of
delamination.

9. 2 // The best of optical quality
NXT technology guarantees optimum optical quality, great visual clarity and
exceptional resistance to wear. NXT lenses are unbreakable and ultra-lightweight.

10. 3. JULBO HIGH-PERFORMANCE LENSES

11. A solution for every situation
Sea, mountain, desert, snow, the light changes with each environment
and our eyesight has to adapt to special conditions. The Julbo range has
been developed to meet the constraints of every situation...
The world needs your vision
For everyone who enjoys the outdoor life, Julbo has used NXT
technology to develop high-performance lenses adapted to the
environment in which you will use them.

12.  Photochromic: protection category 2 to 4.
