The CVF Trinocular focuser replaces your entire 35mm film or DSLR camera during critical focusing. This precision calibrated device projects a portion of the actual image to be recorded onto a high-resolution cross-hair focusing screen which is then significantly magnified by a 5 element loupe. Once you focus the image on the screen, the CVF is removed from the t-ring and replaced with your camera to take the actual picture. While focusing, the already magnified image you see through your microscope eyepiece will be magnified 10x.
This simple swap-in, swap-out process takes only seconds and guarantees perfect focus every time:
* Why It Works In a nutshell, the existing view screen in your camera, whether DSLR or film, does not provide enough magnification and contrast for your eye to obtain perfect resolution during focusing. Your eye compensates for an out-of-focus image automatically by up to 3%. Consequently, while focus may appear to be perfect to your eye, it is not at the exact focal plane expected by the film or chip in your camera. The result is a blurry image lacking definition. By providing enhanced contrast with the focusing screen along with high magnification, the CVF radically reduces the error of your eye down to around only .2 %. And unlike traditional focusing screens and LCD viewscreens, the CVF completely eliminates interference from extraneous lighting guaranteeing perfect focus even in extremely bright laboratory settings.
