Holography question:  Hoping to find green-sensitive plates suitable for reflection and transmission exposures

Go with the VRP-M.\n\nThe VRP-M is good for both reflection and transmission holograms, but it particularly good for reflection holograms, where as the VRP is generally designed for transmission holograms only. \n\nThe emulsions are exactly the same, it just that the VRP has a anti-halation layer that optimizes the diffraction efficiency for transmission holograms. The VRP-M, on the other hand, does not have anti-halation. Since you generally don't want an anti-halation backing for reflection holograms, most holographers who want to do both reflection and transmission work use the VRP-M.

The prism will have higher reflectivity and lower scatter compared to an aluminized or silvered mirror. Also, there is no coating to degrade.\n\nPrisms are less desirable in fast (<f/8) systems because they introduce spherical aberration. For these applications a high quality dielectric mirror is best.

Uh, I'm not smart on this, so I'm guessing here, but...\nSince different frequencies and wavelengths are what determines what color is being reflected, there has to be some way to quantify the amount of each in different hues of different colors.  Does that even make sense?  I don't know...

You can get a hollow prism, fill it with water or some liquid and find its refractive index using a spectrometer. I did that for my ISC exam.

distance measurements...btw...holographs have been developed (not the three beam version but the single immesion source)

Use your greenness-meter.

Depends on the filter.  If it filters out all green hues, then one would see red and blue.  If it only allows green frequencies of light to pass, then of course one would see green...

sure, what you want is an IR filter, which you can pretty easily get from any optics supplier.  here are a wide range of choices from melles-griot, but they're kinda expensive.  however they are quality professional-grade filters.\n\nhttp://shop.mellesgriot.com/products/optics/optics.asp?plga=051408&CatID=10222&mscssid=&Page=All\n\nhere are some cheaper versions with slightly less clean spectra, but probably still functional depending on your needs:\nhttp://shop.mellesgriot.com/products/optics/optics.asp?plga=085680&CatID=1023&mscssid=\n\nyou can probably get some for cheaper if you hunt around on the web.  just be careful you aren't getting the opposite of what you want - a stop-visible/pass-IR filter, which is used a lot in infrared photography.

What you want is an IR blocking filter. An optical supply house like Melles Griot , Reynard, or Edmund can supply you with one.  Depending on the intensity of the radiation, you may be better off using a cold mirror or hot mirror. These are dichroic mirrors that pass infrared and reflect visible light, or vice versa. They can be used where a blocking filter might get too hot from the radiation absorbed. \n\nSchott glasses KG1 through KG5 are some available IR blocking filters.

The short answer:\n\nThe larger the hologram the larger the coherence length needed.\n\nThe holography setup can be thought of as a Michelson interferometer, since the superposition of the two split path lengths taken by the reference and object beams creates an interference pattern on the film plate\n\nFor the hologram to be created, the total path length difference between the object and reference beams must be less than the coherence length of the laser. If the path length were to deviate outside this length, then the phase would not be the same for an object ray and a corresponding reference beam ray. \n\nTherefore, as a general rule the maximum size of the object is limited to about L/N. \n\nWhere L is the length of your laser cavity. \nand N is the number of modes in your laser cavity.\n\nIn our experiment we have a HeNe laser cavity which is 40 cm operating with 3 modes. Thus our maximum object size is about 13 cm. \n\nWe can approximate the coherence length of the laser as L/N.
