![]() To put it simpler, by coating these surfaces in this manner, they are able reduce the amount of stray light they don't want getting inside the lenses, and they are able to increase the amount of light they do want bouncing off the mirrors. The structure of the two scanners are identical, but the V850 Pro has anti-reflection coatings on the optics, and high-reflection coatings on the mirrors, that simply eek out the last bit of image quality we can get from that system.” “The V850 has all of the little extras that we know how to do to make that image quality better. In an interview with Mark Roslon, Senior Product Manager of Epson America, Inc. High-reflection coatings on the mirrors.But, with the flagship V850 Pro model, Epson decided to take the image quality one step higher by adding what they call “ High Pass Optics“. The purpose of the 850 Pro is to pull out every last possible amount of quality from the scanner using some additional internal design refinements to ensure minimum optical distortion: ![]() ![]() You won't find a two-lens setup like this on even the next model down in the lineup - the single-lens only Epson Perfection V600 Photo. And when you are scanning film in the included film holders, it will then automatically choose a second “super resolution” lens capable of scanning at 6400 dpi (optical). (This system was also available in the V700 series the V800 series later replaced) This means when you scan a paper print, the scanner will automatically use a high-resolution lens capable of 4800 dpi (optical). Both scanners are equipped with a Dual Lens System - unique to the V800 series of scanners in their current lineup. The Resolution defines the amount of details in your scanned image.Īdditionally you can use the USM (UnSharpening Mask) to sharpen the images software sided.If you've stared at photos of the V800 Photo and the V850 Pro, you've probably noticed they look fairly identical right? This is in fact because other than the identifying name written across the top right front of each device, their physical casing is exactly the same for both. The standard position is indicated by the arrow shaped notch.Īlso make sure that you have selected a sufficiently high resolution. The V800/850 holders have sliders which allow to place the holder in a slightly lower or in three higher positions. This is changed by either inserting the feet so the arrow points towards the normal (0) or the slightly higher (+) position. The V700/750 holders have feet which can be switched to two different settings. You can further control the focus by adjusting the hight of the film holder. This mode offers the maximum resolution and infrared correction. A film holder should always being used while this mode is active. The Filmholder transparency mode places the focus at the hight of the film holder. The maximum resolution in this mode is limited and it can not offer infrared correction. Please note that the transparency area is slightly smaller than the glass plane. The Glass transparency mode also places the focus at the surface of the glass plane and scans the entire width of the transparency unit. The Reflective mode always places the focus at the surface of the glass plane. The focus layer being used is controlled by the scan mode which is in use. It can only switch between two separate focus layers. The EPSON Perfection series has a fix-focus lens system.
