3.5X Fisheye® Conversion Lens

Product catalog summary

Key Advantages:

Improved illumination and reduced distortion at the edges of images.
Ability to fully capture all 1920 pixels at the widest prime lens zoom.
Enhanced image quality with higher optical MTF (Modulation Transfer Function).

Applications:

Planetariums
Amusement Parks
Simulation environments

Product Overview:

The Navitar 3.5X Fisheye Conversion Lens is designed for use with lower-cost projectors that lack replaceable lenses. It is particularly suitable for planetariums looking to upgrade without purchasing new projectors or lenses. This lens is also ideal for applications requiring wide projection angles on curved surfaces, such as simulations and immersive environments.

Catalog excerpts

Navitar’s 3.5X Fisheye Conversion lens is designed to work with lower cost projectors that do not have replaceable lenses. This is an ideal solution for planetariums that want to upgrade their existing systems, but can’t afford to buy new projectors or replacement lenses. The new 3.5X Fisheye will also work in many applications where users simply want to project a very wide projector angle onto a curved surface, such as simulation, immersive environments, and amusement attractions. Key Advantages: • Better Illumination at the edge of the image • Lower Distortion at the edge of the image • Fully capture all 1920 pixels at widest prime lens zoom • Better Image quality (Actual optical MTF of lens will be higher) Applications: • Planetariums • Amusement Parks • Simulation •without vignetting
