In the Warm Polarizer filter, Tiffen combines the properties of the polarizing filter with the exclusive effects of the 812® Warming Filter. This valuable filter adds natural warmth to all skin-tones, exterior shade and highlight areas. This is useful in outdoor open shade situations where there is excessive blue in the image and total control over lighting may not be possible.

The tool Gauss Beam Calculator computes some free parameters of the Gaussian beam when changing one of its parameters and fixing some others. As it is not possible to make all the parameters to be free, we introduce two fixing modes called Lock waist and Lock front.

A circular polarizing filter absorbs rays of sunlight, by rotating the ring you control the effect. A Circular Polarizer is used on cameras with beam splitting metering systems commonly found on auto focus SLR’s (for most 35mm auto-focus cameras see your camera manual). The Standard Circular Polarizer filter blocks 1.5 stops of light and is one of those must have filters.

Polarizing filters provide color and contrast enhancement. Reflected light often shows up as whitish glare that washes out color in an image. A Polarizer filter corrects this problem producing deep, dramatically blue skies. It also removes glare from non-metallic surfaces, such as windows and water. Color saturation in general, especially outdoors, can be improved significantly. Standard Polarizer filters blocks 1.5 stops of light.

How to find z: substitute z0 as w0/Vs into formulas for w(z) and R(z), express w0 from both, equate them and solve against z.

Lock waist - find such values of free parameters at which the beam waist w0 stays constant when one of the parameters changes.

Find beam quality parameter M2 giving specified beam radius at the same axial distance z and with the same waist radius w0.

Assigning either real or imaginary part of complex beam parameter, we define both the beam radius w and the wavefront ROC R at the same time.

For specified Vs, find such a distance z and beam quality M2 at which the wavefront ROC keeps its previously calculated value.

Fixed Focal Length Lenses ideal for machine vision systems with demanding space constraints and industrial C-Mount cameras are available at Edmund Optics.

The low light polarizer has less of a polarizing effect than a standard polarizer filter, allowing for it to be used in indoor and darker situations when available light is at a premium. Low light polarizer filters require 1 stop of exposure compensation, instead of the standard 1.5 stop compensation.

A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves.

How to find z: express w02 from formula for R(z), substitute the expression into formula for w(z) and solve it against z.

Quadratic equations have two solutions and we have to define a way to point out which solution to take. So the tool has one additional parameter - zone - which can be Near zone or Far zone.

For specified waist radius w0, find such a distance z and beam quality M2 at which the wavefront ROC keeps its previously calculated value.

For specified z0, find such a distance z and beam quality M2 at which the wavefront ROC keeps its previously calculated value. + sign is for the far zone, - is for the near zone.

Changing of real part is equivalent to changing of wavefront ROC R, and changing of imaginary part is equivalent to changing of beam radius w.
