We have asked Polaroid for answers to the following questions about their newly announced "Pro" line of 3D glasses. We'll fill in the blanks when the answers arrive. We meet with them on Tuesday, 13 September at IBC. The Press Release closes this article.
What is the light transmission spec for these specs?
What is the polarization efficiency?
These are the questions asked, and now answered during an email coorespondance:
Given that darkness is the main issue with 3d and typically glasses contribute to that darkness by some varying degree... How good can polaroid get with circular polarization – We have a transmittance of 42-44% which is as high as one can get without loosing polarizer efficiency. We are looking at AR coating to further improve this value.
What is the light transmission spec for the specs? – 42-44%. More importantly is the transmittance of the polarized light, which in our case can reach as high as 84 to 88%.
What is the polarization efficiency? – It needs to be 99.9% in order to maximise the 3D effect.
Are the lenses matched left and right- tests have shown that this is a common problem with those glasses – From a transmittance point of view, yes.
[It is obvious that there a lot to learn if we're going to ask the proper questions. Back to the original article.]
Are the lenses matched left and right - tests have shown that this is a common problem with some glasses.
Is there an AR coating on the inside? Does this reduce transmission more than it helps internal face glare?
Part of the problem that "Pros" face is that they have to look up at 3D screens while they have to look down at computer keys and editing levers and knobs in 2D. They need a dual lens solution, maybe even the ability to have their doctor etch their prescription into the bottom of the lens. Has Polaroid accommodated for this?
Is this line being sold direct through Polaroid?
We wrote an article last year whenn Polaroid announced a line of 3D glasses for consumers. Wonder how that went. RealD and Polaroid — Possible Promise PR.
Here is the new press release:
Polaroid Eyewear Launches Professional Range of 3D Glasses
Zurich, Switzerland, 9 September 2011 – Polaroid Eyewear today announced the launch of the first two styles in its Professional 3D Eyewear Collection.
The Polaroid Professional 3D Collection, which uses passive circular polarization, has been specifically created for 3D professionals and producers of 3D content. These first two styles both have interchangeable lenses, meaning that after work, professionals can simply change the lenses and use them as stylish sunglasses.
The frames are produced using premium quality materials and precision, making them both lightweight and robust. The lenses are produced using ThermofusionTM technology, which is exclusive to Polaroid Eyewear and ensures distortion-free vision.
Polaroid Eyewear already has a wide range of consumer 3D glasses on the market place, which offer high quality and comfortable viewing, and can be used with passive 3D systems, such as RealD and masterImage, as well as a number of passive 3DTVs.
Both the professional and consumer ranges have curved lenses, which wrap around the sides of your face and therefore block out any excess light, providing high contrast vision right across the lens.
“Polaroid Eyewear’s entire range of 3D glasses combines stylish design and expert technology to deliver great quality passive circular-polarized 3D glasses.”, commented Eva Dudek, Marketing Project Manager, Polaroid Eyewear. “With the Professional Range we have taken that one step further to give professionals extra comfort for long viewing periods, as well as a picture-perfect 3D viewing experience.”
The collection is due to be expanded shortly and will offer a choice of exclusive high quality styles.
