Our microscope objectives are broadband AR coated and designed for diffraction limited performance across the entire visible spectrum. This allows collimated beams from lasers such as HeNe, Argon, or frequency double Nd:YAG to be focused to a small spot for spatial filtering. In spatial filtering, a laser source is focused to a diffraction limited airy disk spot pattern. A pinhole is placed at the focal plane sized such that only the central lobe of the airy disk may pass through. This removes undesired higher spatial frequencies to produce a clean uniform output beam. Please see our Three-Axis Spatial Filters and our space-saving Compact Five-Axis Spatial Filters.

Our M Series objective lenses are broadband AR coated and designed for diffraction limited performance across the entire visible spectrum. This allows collimated beams from lasers such as HeNe, Argon, or frequency double Nd:YAG to be focused to a small spot for spatial filtering.

Ellipticalpolarization diagram

Our M- microscope objectives are corrected for a rear conjugate at 160 mm, and this family is the most popular family in the microscope objective offering. The M- series is currently available in a range of powers from 5x to 20x. If cost is an issue, the MV- series is the economical choice for standard laboratory applications. Please see Economy Microscope Objective Lenses.

The electric vector is usually taken as the polarization vector. The electric field exert force $-eE$ on the electrons of the atom and the electrons will get the acceleration $-eE/m$. The strength of the magnetic force $-e(v\times B)$ is ~$1/c$ times smaller than the force by electric field (where c is the velocity of the light). Almost all the properties of the light with matter comes from its interaction with electrons inside that matter. Based on these facts the direction of electric field becomes the natural choice of the direction of polarization.

The polarizing-crystal actually filters-out the magnetic-component and allows only the electric-component only, like this-

in an event of a plane-polarization, the polarizer-crystal does NOT separate the electric-component and magnetic component of the light. The magnetic component after polarization is just Not drawn to avoid some (?) complications. So ,

Fig 2. If we could show the magnetic field, it should look like this. Fig 2a when we would see from side, fig 2 b when we would see from front. (in fig 2b i didn't used double-headed arrow because i shown condition of one moment.)

What ispolarizationin Chemistry

Fig 1. the vertical arrows is just an abbreviation showing the vertical electric field, and not showing the horizontal magnetic fields. (in fig. 1 the dot-sign indicates we're viewing the ray coming towards our eye). (In the right-side, realistic image, i did not shown double-headed arrow b'coz i've shown condition at one moment)

So, My question is, which-one of the concept of linear-polarization (from above 2) is correct? If both is wrong, then what would be the correct concept?

The polarizers are the materials which has easy movement of electrons in one direction (pass direction) and restricted movement in perpendicular direction (block direction) resulting in more absorption in block direction (Such as wire grid). Hence light wave which has electric field parallel to the pass direction is passed.

As stated in the comments, an electromagnetic wave can not consist of only an electric nor of only a magnetic field. They go hand in hand.

Circularpolarization diagram

The M-20X is highlighted here in a laser engraving example. This example highlights the fact that these objectives can be used without issue. Unfortunately there is no specific data for actual laser damage. For any high power application, due to the sensitive nature of the environment, the level of cleanliness, and laser power homogeneity, the objectives cannot be guaranteed to perform without damage.

Both of us searched internet for hours make the dispute clear, but I could not display them any diagram that displays that , after being filtered through a polarizing crystal, the wave retains both the components. So they didn't believed this and stood on the same point (fig. 3)

Magnetic field will remain same until unless you are using ferromagnetic materials. It may be noted here that even if you choose a medium in which one of the field components is absorbed preferentially, as soon as the light leaves that medium (if at all it can leave the medium) the stronger component will reproduce the depleted component naturally such that their strength become equal (as in normal case).
