Can these filters be used to polarize a phase contrast microscope or a transmitted light microscope?

It is possible but I wouldn't recommend them because their optical quality is not good enough for such applications. Use a good quality glass polarizer.

You can, but have to set the polarizer after focusing. Typically not a problem for distant / landscape shots as the ring is mostly around infinity focus.

There is no indication of filter size in the manual: (http://www.general-imaging.com/uploadedFiles/10_Our_Cameras/Cameras/Power_Series/X5_UM_En.pdf) so I would think not. You might be able to rig up something, but that might be more trouble than it would be worth.Not too many low-end digicams provide for filters without some sort of adapter; a shame since a polarizer can do wonders to an otherwise mediocre image.

Dinosaw,I've used these star filters in astrophotography to highlight bright stars. They don'tadd any distortions at all. Zero chromatic aberration, no vignetting as long as theyare stacked with other filters, and no detectable edge distortions. If you want tocreate highlight effects on bright objects, I highly recommend these filters.Best wishes, Ron Smith

As long as it stays on the lens and doesn't drop off you are probably OK. A polarizing filter needs to turn, that's how you adjust it to the maximum effect.

I don't believe they are polarized, but they do have uv protection. And the clarity they provide is unmatched, afield I can even distinguish individual blades of grass easily.

It depends upon what you want. I use polarizing filters and a few other. If you purchase i good quality such as B&W; they will not affect your quality. I use a filter to protect my lens especially in dust or sand. You Don't need to have a filter on all the time

If your purpose is to use the gels as a polarizing tool to photograph artwork and reduce glare, my sense would be that the gels should be used without diffusion. To diffuse the light reduces the directional quality that the polarization of the gels produces.Be sure to put each gel in front of each light in the same direction and then using a polarizing filter over your lens, rotate the camera filter 90 degrees to the angle of the gels. That way you will remove as much reflection as possible. Best of luck.

No built in polarizing filter. You would have to take off the lens cover and even then I don't think there is a filter made to fit. Might be able to add the converter extension and put a filter on it but I haven't researched that enough to know for sure.

LCD TVs have polarized filters. Lasers emit only one polarization. Turn the pointer 90 degrees. and you'll be able to see it. Green, red, blue doesn't matter, it's all one polarization.

Yes you can, it's called stacking, but why would you want to? If your going for some sort of in camera effect then the effect that you get would depend on a variety of situations like, the order in which you stack the filters and the type of lighting your shooting in. Keep in mind that when you stack filters you lose resolution and light. I know of occasions where a polarizer and a fld are staked in order to correct for fluorescent lights and blueing of the sky, so to speak. I hope this helps.

Art filters are special effects applied by the camera in software. A circular polarizer would be a hardware filter, which could be screwed in once the lens cover is remove. But the lens barrel is not marked with a filter diameter.

Yes, but the threads for the filter are not very deep, and it falls off easily, especially the polarizer, unless you always rotate it in the correct direction (as in screwing it on.)Kathi

So... these filters serve two different purposes. The UV filter that I purchased is on my lens to protect the first element when I'm in situations that require me to be less than 100% diligent about where my lens is. A hood serves the same purpose so I supposed it is kinda redundant redundant... The Circular Polarizer is designed to reduce glare coming off of non-metallic surfaces. It can add "pop" to landscapes and cloud scapes much in the same way that polarized sunglasses do for your eyes. They do reduce the amount of light that makes it to your sensor and you'll need to take this into consideration. Hope that helps.

Dear D.E.-CPL Filter (Circular Polarizer) is used for removing unwanted reflections from non-metallic surfaces such as glass or water. Take richer scenic shots and notice improved clarity in distant objects by cutting through haze and increasing color saturation.This filter is mounted on a rotating frame allowing the user to determine the desired amount of reflection to be removed by simply rotating the filter.-FLD is used for shooting under fluorescent lighting. Bring warm natural lighting to rooms that would otherwise be washed out by unappealing fluorescent lights. I hope I was able to answer properly your question.Have a good dayCustomer Service Dear D.E.-CPL Filter (Circular Polarizer) is used for removing unwanted reflections from non-metallic surfaces such as glass or water.

I believe they protect your eyes. My lens implants filter anyway. They are not polarized.

Yes, one of the filters is a circular polarizer. However, it does require a 40.5 mm thread to attach to. I have a Nikon 1 V2 with the 10 - 30 mm lens, and it does have a threaded filter mount.
