This listing is for one (1) Dove Prism. I do not know the wavelength properties of these prisms as they have no information provided. The physical size of the prism is 75.5mm on the base, opposite the base or the top is 41.25mm, the hypotenuse is 25mm and the width and height are 18.2mm. The corners are beveled for protection and there is a opening in the top which allowed a small metal insert to be installed. These prisms have the dark coating and metal insert for mounting. This listing is for one coated prism that was stored in open packaging. Prisms for commercial applications are stored in sealed wrappings and not touched by a ungloved hands. These are in unused condition and have amazing high polished ends and base but have not been stored in protective packaging. So although these prisms may have commercial applications I am selling them as "For Experimentaiton" as they have not been stored in sealed packaging and have unknown properties. You will receive one (1) prism that has been inspected with a magnifing glass and found to be free of visaible defects. This is not to say that there may be micro scratches. From packaging I have from other prisms that came with this lot I would estimate that these were manufactured in the 1950's. Check out my other listings for similar prisms that aer uncoated and do not have a mount. For your information when viewing through the ends of the prism the object being viewed is seen inverted. When the prism is turned 90's the image is seen as normal The ends and bottom have the polished surfaces and the sides and top are not polished and opaque. Buyer pays $4.00 USPS shipping and handling in the 48 States and a PayPal is required after the purchase. No additional shpping cost if you buy multiple prisms. These will be wrapped in a lint free wipe, then protective wraoped and shipped in a bubble envelope.
