Is it possible to have a non tinted linear polarizer that has at parallel transmittance of 80% but a crossed transmittance less than 1% please help me out with this
No one else has this question

Agilent doesn't make or sell polarizing film and I'm not particularly familiar with what is on the market. Maybe some of our other participants can add information.
But 80% transmission for the desired polarization (40% for unpolarized light) seems to be a pretty high quality film and I don't know where you will find still higher transmitting film. The <1% transmission for the rejected polarization should be realistic. I think such film can be obtained from some of the general optical and scientific suppliers, whose catalogs are on the internet.
For higher performance you will probably need to use a polarizer based on coated glass or prism optics. These are often available from the same suppliers. Of course they are not available for such large areas as film if that is also important.
Since you use the word "tint" I guess you may be looking for a polarizer for the visible wavelength region. Anyway the specifications to the wavelength range will be important to match to your need and a wide range with good transmission would indicate that it is "untinted".
