The Pin-hole lens design is ideal for use in camouflage video systems.
Conical lenses are designed to use an outer screen formed by masking elements.
Sharp cone lenses are designed to work without an outer aperture because it is formed by a small exit aperture of the lens.
Flat lenses are recommended when using thin masking materials.
Compatibility with the matrix size of the TV camera must be taken into account when selecting the lens thread size.
The actual viewing angle depends on the specific type and size of the visible area of the television camera matrix and its resolution, and may differ from the resolution given in the table.
Viewing angles were measured using a TV camera based on a 1/3 "CCD SONY ICX259AL 1/3" CCD and an ASX340AT APTINA 1/4 "CMOS matrix.
