Paraxial ray approximationcalculator

Available in various sizes, with typical dimensions being around 20" x 20", accommodating different depths based on specific requirements.

In analyzing lens systems, it can be helpful to make the approximation, referred to as the paraxial appoximation [3], that the distance r and angle of rays from the optic axis is small. This can allow approximations such as and . In a cylindrically symmetric lens, we may also assume that the radial force is a linear function of r by ignoring terms in the series expansion [1]. Transfer Matrix methods can also be applied. The term occurs in other areas as well, notably light optics [4] [5].

Made from dual-density polyester media, this filter incorporates a dry tackifier to enhance efficiency. The filter's frame is constructed from heavy-gauge metal, providing robust support.

The filter features two deep pockets designed to optimize airflow and maximize paint holding capacity. The filter configuration ensures low initial resistance, which helps maintain its efficiency over time. The polyester material is durable, with a coarse first layer followed by a denser, needle-punched layer to trap finer particles.

Ideal for use in automotive, aerospace, and industrial painting applications, these overspray cube filters are a cost-effective and environmentally friendly solution for capturing and filtering paint particles in spray booth exhaust systems. They are perfect for maintaining high air quality and ensuring a clean working environment.

Commonly used in multi-stage spray booths, particularly in automotive, aerospace, and industrial painting settings. It’s a high-capacity solution for capturing paint overspray.

Paraxial ray approximationclass 10

SIMION-specific: SIMION does not impose the paraxial approximation because it can just as well, in the general case, perform a complete calculation of the ray (direct ray tracing), but the paraxial approximation is still a useful concept for describing and reasoning about systems, and it can be observed. See also Lens and SIMION Example: lens_properties.

Notice that at low values of radius (y, also known as r), the second column is fairly constant and the last two columns (for measured and estimated radial field component) match closely.

As an example, load the SIMION Example: einzel (3D cylindrical Einzel lens) and execute these lines in the command bar (using the SIMION 8.1 simion.pas API):

Designed for optimal performance in multi-stage spray booths, these polyester cube filters feature dual-density polyester fiber construction that ensures even airflow, full inflation, and minimal resistance. Combined with deep pockets, the cube configuration allows for low initial resistance and maximizes paint-holding capacity, providing superior filtration for paint overspray.
