Electronically Variable Illumination Filter for Microscopy

摘要

An illumination system for diascopic microscopy comprises a computer (610) with memory (625), a graphics program (605), a display driver (615), and graphical display (600). The display is positioned between a microscope's light source (105, 704) and condenser (110). When activated, the illumination system causes the display to display a predetermined pattern which the light source projects onto the condenser and is then focused by the condenser on a subject (125) to be examined. In conjunction with the microscope's light source, the illumination system emulates the illumination techniques of bright field, dark field, oblique, polarized, monochrome, modulation contrast and phase contrast illuminations.

主权项

1. An electronically controllable optical filter system for use in microscopy, comprising:
a computer, wherein said computer has activatable controls, a memory connected to said computer, a program of instructions operable within said computer and said memory for controlling the operation of said computer, a display driver connected to said computer, a display connected to said display driver, wherein said display displays predetermined graphic images that are selectable by said computer, wherein said computer selects said graphic images from said program or said memory, a microscope having a light source and a condenser for illuminating a subject, means for securing said display between said light source and said condenser of said microscope, whereby when said light source is activated and said display is activated and secured between said light source and said condenser of said microscope, and said controls cause said display to display said predetermined images, said filter causes said subject to be illuminated according to said predetermined graphic images in said display.
